What are you guys getting?

[GoLfMan]

Hi guys,
just filled the polo up for the first time. Dad and i worked it out we got an economy of 5.67L/100km around town and thats on a tight engine.
what are you guys getting economy wise?

[brackie]

TDI: 5.3L/100 on mixed running, 5.0L/100 on highway.
Silver Mk1 GLD: 4.7L/100 on mixed running, 5.0L/100 on highway.
Red Mk1 GLD: 5.0L/100km on mixed running, 5.2L/100 on highway. (Has additional weight of sump guard, aircon and sound proofing.)

[Seano]

2.5 Tdi in a Transporter Dual Cab with syncro.....routinely hitting 8L/100km round the town blowing out to 12L/100km on the open road....it's all about revs for me

[LS1 Cobra]

7.1L so far 1/3 of the way thru it's first tank. Mostly round town stuff. I'll do the sums when I fill up and get an accurate figure.

[GoLfMan]

TDI: 5.3L/100 on mixed running, 5.0L/100 on highway.
Silver Mk1 GLD: 4.7L/100 on mixed running, 5.0L/100 on highway.
Red Mk1 GLD: 5.0L/100km on mixed running, 5.2L/100 on highway. (Has additional weight of sump guard, aircon and sound proofing.)
they are some impressive figures brackie!
did you get my PM mate?

[brackie]

I got your pm and replied. Been distracted a bit by other forum issues. Kinda dampens your enthusiasm :(

Not all diesels are created equal. This is a fact of life and time and time again I have seen cars/vans/trucks that should on paper be returning the same fuel consumption getting different results. Those with in-line (multi-element) injection pumps seem less variable, but distributor-type pumps like the VE are very sensitive in the governor area and must be timed accurately to achieve the best results. Most guys know about the "smoke screw" (so called because if you open it you get more smoke and more performance but use more fuel but really a maximum fuel device) so they have a bit of a twiddle. I don't have access to bench test apparatus anymore so I twiddle too and try to achieve a balance between performance and economy. Last time I went to Hobart in the silver Mk1 GLD I had to change the settings of the screw to cut down the smoke in the Hobart traffic. Didn't want an infringement notice or worse still a work order. When I was at Andrew's workshop I borrowed tools to do the adjustment but the next day on the cruze with the other Hobart crew I found it difficult to keep up with them. Andrew also lent me a dial gauge and probe so that I could set the point of injection accurately.

The biggest variable in diesel fuel consumption is the driver. Drive it like a petrol engined car and you'll get petrol engined fuel consumption. Use the torque band and you'll get there faster and use less fuel.

[brackie]

Had a disappointing run to Launceston and back today. The TDI did 5.2L/100km for the trip. I came back across the Asbestos Range which worked her hard but I expected better now she's loosening up. Worked out @ ~ 54mpg using 1g + 4.45L and 1km = 0.625ml.

[gtimk5]

About 40,000 kms before they really loosen up Brackie, then the things go heaps better and the consumption improves even more. I had a 2l TDI at work today with 15ooo kms on the clock. He achieves 1150 kms to a tank!!:)

[GoLfMan]

wow! awesome Andrew.

Brackie i didnt get your reply mate?

really loving the Polo, ive learnt how to drive it on the torque curve, also i have learnt the boost characteristics :) it calls for a great fun drive. Its hard to stay under the speed limit :(

[gldgti]

with 4-speed box, would get 5.3l/100km moslty mixed

5-speed box is getting me 4.9l/100 km mixed.... must be low 4's on strict highway driving

[LS1 Cobra]

My first tank of fuel in the Jetta got me 671KM and I put in 49.31L when I filled up.

By my calculations that's 7.35L per 100KM.

Most of it was running to and from work and round town so not too bad I guess. I figure it'll have to improve as the engine beds in.

My wifes going for a run up country next week. It'll be interesting to see what economy she gets.

[GoLfMan]

we just filled up again, after about 1400km's we are averagin about 6L/100 around town... not bad but should improve as engine frees up :)

[Moonan]

The economy of these VW TDI's is pretty amazing, and even extends up to the big toys...
My daily drive is Newcastle-Muswellbrook & return, mostly country highway but with a bit of traffic, a few km of freeway, and several small towns along the way. In fact there are around 54 different speed limits on the round trip of around 220km (unless it is school zone time in the afternoon then it is 60).
For a tank-full of diesel, this tends to average 8.6 l/100km in the Touareg (with around 50k on the clock). Remember this thing weighs in at 2.4 tonnes.
Now I've done some tests...
Using Biodiesel (approx B50) this rises to 9.4, but if you add in a DP chip (still on the B50) it improves to 8.4!
With D2 (ordinary) diesel and the chip, that has improved further still to 7.9 this week. Thanks to the nice man at Newcastle TJM for letting me try the chip for a week with no obligation to buy.

[peter_j_g]

I have averaged 4.5 l/100km over the last 15,000km in a 99 passat tdi wagon.

Brackie - interesting the difference in consumption betweeen the silver & red mk1s. I had been adjusting the "smoke screw" too to get the best compromise between emmisions & performance. There is quite a clear sweet spot in the adjustment where any less fuel impacts performance and any more just produces smoke! I used to verfiy the adjustment on a nearby steady steep hill, 2nd gear and note what speed it would hold. I used to average around 5l/100km around Sydney.

Also is there any difference in the tyre sizes between the two cars? I have noticed with the passat that fuel consumption rises by about 0.5l/100km when using studded winter tyres (compulsory here for 5 months of the year), however most of the difference is actually due to the winter tyres being slightly larger in diameter, although they are the same nominal size.

Rgds, Peter

[TDI DSG]

Does anyone have any preference for brands of diesel based on experience with results of performance and or economy ? I was of the opinion that it should all be the same but filled my fourth tank with a different brand and felt there was a perfomance and economy difference...

[neo25x5]

i noticed today that the over fuel consumption on my new jetta fsi is 7.8 p/100km. i thought that was pretty good given the published figure of 8.6. granted i do a fair bit of highway motoring, but i also don't like to thrash her either. :)

[GoLfMan]

we just filled her up again!!!
we are now averaging 800km to a 45L (about 5.6L/100km) tank around town, and thats with varied driving conditions (some full throttle applications ;))
not bad at all.... we have been using BP Diesel the whole time :) just out of convienience really.
isnt BP diesel reccommended by VW?

[brackie]

I got the TDI to 4.7L/100km for a full "trip" the first time last week. It was on a 100km mixed run of hilly country roads and dual carriageway. Haven't been able to do it again (5.1 is the best).

[LS1 Cobra]

Are these the figures you are getting from the display on the dash or from calculating the number of litres filled to the KM traveled?

I'm begining to think the dash display can be a bit optomistic sometimes.

[brackie]

From the Multi Function Display. I reckon mine's OK as I have checked it against actual fuel on a couple of occasions.

[GoLfMan]

The polo doesnt have dash display calcultor, so i just do the calculations myself :)

[gmhendo]

My Mk1 1500cc unmodified consistently runs 4.8 litres/100, 90% highway running , and speeds between 80 & 90 kph. It just seems happy around that speed range. I did change my brakes over to vented and larger rotors after I tired of the original calipers sticking and causing drag. That was costing me around 1 litre per hundred! I have no idea how many miles the car has done, speedo failed at 94K, but that's all fixed now. At a guess, maybe 250K. Does not use oil, starts after a few revolutions, little bit of smoke (after the start puff), then runs clean.
For the time being I would love some bolted vents....anybody got some, with frames?? Actually I would settle for a LHS only... OH yeah and a supercharger for the motor.....j:

[reverb]

Currently heading for 500km on just over half a tank of dealer-supplied diesel in the Polo TDi. Yep - first tank. What an awesome little engine this is!

And this has been shall we say taking liberties at the traffic lights due to the amount of power off the line this thing has. Should settle in to some nice figures by the time it has loosened up.

good to see a fellow Polo TDi member :D they really are a great little car arent they... pretty perky ;)

[Macca]

Just got home (Adelaide) from a trip to Sydney etc. Jetta TDI DSG.

I got to Hay and thought it would be good to top up the tank but the nozzle at the servo would not fit and was told they were all like that in Hay.

A bit p***ed off I got to West Wyalong 928.5 K from home. My biggest concern is the car took 52.85L, (fully loaded 5.7L/100, 49.6mpg @ 110km/h gps, 120km/h car speedo) thats only 2.15L left

What would happen if I let it run dry?? Do you have to bleed injectors or something?

cheers Macca

[brackie]

thats only 2.15L left

Should get you ~80km

Modern diesels don't have to be bled.

[gldgti]

Modern diesels don't have to be bled.

yay for the VE pump!

[GoLfMan]

the economy of the TDi Polo is still improving after many months :) now getting 800km to a tank around town!

[Rod_H]

I am getting about 800-850 out of a tank i am on my 2nd tank from new.
The last tank I got about 540 at halfway mark...
Ive done 1900kms in 2 weeks..

[DubSteve]

Sorryn Guys couldn't resist.

My vr6 13.5 L/ 100kms lol not very fuel economical in the city highway driving to Penrith I got it down to about 8.2L / 100kms wasn't to bad still the dielsels beat it lol ;)

[william]

i wish i had mfa so i would know but roughtly 50dollars a week not bad for a vr6

[ScottH2155]

I've had my 06 Jetta TDI/DSG since November. Getting 800km around town and at Christmas went from Sydney to Brisbane on a tank, avg 5.2l/100 on the way up and 5.3 on the way back. She's got about 8000km on her now.

As my first VW and my first diesel, I'm still impressed and happy with my purchase.



Macca - although the high flow (large) nozzels don't fit, you can dribble in fuel, just watch for it to froth up. You'll take 5 mins for 10-15 litres, but it beats running out.

Smartest thing I've seen - a Brisbane servo - had both hi-flow and regular hoses on the one pump.....should be more of it.

cheers..scott.

[The_Hawk]

This is another of those things on my list of "things to fix", the odometer and trip meter in my Mk1 are busted, they tend to sick on 9/10ths every time round.

But last trip I went on I did Coffs Harbour to Campbelltown which is about 600kms on 30L, so ~5L/100 K's or less.

This is in a 79 GLD with a 5 speed.

my mk1's beutiful to drive.... apart from the noise, the water that comes inside, the barely adequate brakes and rusty 30 year old shell.

it feels like the best thing in the world.

[Trunch]

I picked up my 2.0 DSG Golf Sportline last wednesday and now have about 1100km at 6.6L/100. Needless to say I am very impressed with the economy and the sheer grunt of the Golf. I can't wipe the smile off my face.

[The_Hawk]

what are they like to drive?

It's quite good to drive, although as with every VW in existence, there is always a list of things waiting to be fixed, like the shake it develops at 110+ (even though everything has been aligned and balanced)... The amount of smoke it blows under load...

But really, for a daily driver is a very neat tidy little car :) (Mind you I still miss my Type 3 :( )

[Edison]

Hi Brackie, Can you tell me what is your highway cruising speed(s) ? (or range of speed)

[brackie]

Hi Brackie, Can you tell me what is your highway cruising speed(s) ? (or range of speed)
I have never trusted the speedos and I reckon they're about 8 to 10% optimistic.....but.... I cruise @ 100kph comfortably and she will do 110 all day long....but... there is a significant fuel penalty for that extra 10kph.

[gldgti]

i've been doing a LOT of hyway driving lately....

i cant get worse than 5.6l/100 km, even going 120/130 mostly... but thats with the 5 speed, and my car is quite low as you guys know.

[briseos]

2005 2.0TDi Sportline Golf - love the way you can drive it hard around town and use all that beautiful torque, make screetchy noises off the line in 1st, 2nd and 3rd gears (DSG) and still walk away with less then 6.5l/100k -

BUT

IF you get stuck in trafik, you get 8+l/100k..... might as well do the rat runs and circumnavigate the globe than sit in trafick!!!

Incidentally, my Satnav (Navman N60i) tells me CONSISTENTLY that the speedo is exactly 10% optimistic - and this error corrects the fuel consumption calculations on the trip comp too!! (Have actually verified Satnav speed at 60, 80 and 100kmh via trafick cop mate!

[Rod_H]

My 2.0TDI has about 8500 km's on clock now, my run to and from work is a pain, stop start, 50kmh zones 2nd 3rd gear crapola. It gets around 6.6 to 8.0. I can never get a run long enough for it to get into a good gear...

On the freeway it get's down to 5.0 is the best Ive seen so far.:rolleyes:
But she's a hoot to drive.:D

[Volvo Driver]

Dad's Mk3 tdi used to easily get 5l/100km's when just going to work and back, which is down the monash then down princess highway, and usually it's about 6l/100km's, it's gone down over the years since bought as I'm sure the intercooler isn't running as efficiently as it should be abd the oil changes are too far apart among other things, but if I ever get it, it will be back down to those low economy marks, oh and the 6l/100km figure is with hard launches and stuff like that.

n our N/a 2.4 T4 transporter, we get 10l/100km's out of a tank, and slightly less when towing our hovercraft and other gear, but it revs it's head off in 5th at 3000rpm and when towing it won't go past 100km's, even without towing but with a full van, you can have the foot flat to the floor and barely do 110km's, downhill!

[gldgti]

i've just been naughty...

way back from work on the freeway, thought i'd see how slow the old girl goes.... relatively flat, i had about 400m of road until the next cars - the old 1.5 n/a managed 145, still had plenty of pedal left too!

[Rod_H]

:o :) Very Nice (Borat voice)

thats not bad at all for 33kw's :D

[Volvo Driver]

That is excelent considering my dad's old B1 passat maxed out at 130km downhill and our van maxes out unladen at 135 and 4500rpm, on level ground.

[brackie]

Yeah, but don't forget Ayden's Mk1 has a 5 speed. Is that an overdrive box, Ayden?

My Mk1 gets to 110kph no probs but has a real struggle to hold it once it gets to a hill.

[Transporter]

Hi guys,
just filled the polo up for the first time. Dad and i worked it out we got an economy of 5.67L/100km around town and thats on a tight engine.
what are you guys getting economy wise?

Hi,
I've got Golf V 2.0L Tdi DSG done 1500km and today when I filled up I've got an economy of 6.2L/100km mostly city driving and short trips too. Lowest I saw while driving 65km/h throgh several intersections at night was 4.2L/100km and at the end of that 22km trip computer was saying 4.9L/100km.

I'm also aware that some petrol station cheat and we pay for more fuel than we have in the tank.

[GoLfMan]

Yeah, but don't forget Ayden's Mk1 has a 5 speed. Is that an overdrive box, Ayden?

My Mk1 gets to 110kph no probs but has a real struggle to hold it once it gets to a hill.

it would have to be because the ratios on the GTi 5 speed would be way to short for the diesel powerband...

thats pretty good :) i think my dads Polo is still getting about 5l/100 around town!

[gldgti]

yep i have the 4+e overdrive box.... so i would "guestimate" its doing about 3500rpm at 145km/h

Hi Guys,

I was travelling last weekends on my Passat Wagon 07 TDI from sydney to melbourne. It was able to do 1040km/ full tank (70L) with aircond all the way.

My engine was only 1668km on the clock. It was showing a pretty good fuel
consumption. I am very happy :D:D only cost me $84 dollars for fuel a week in melb (dandenong, st kilda, glen waverly, springvale, richmond, mount martha and boxhill( pickup my jamo before heading home to sydney).:D

I saved big dollars on air ticket..( 4 persons x airticket). I claimed it all through my company.. business expenses...:D

I believed it should do more when my engine lose.. I booked for oil and oil filter
change this saturday at Barlworld..(32xxkm)..

wooowoooo

[njg02]

I've just done my first 1000km tank. Got 1040km with 30km to go. Golf V 1.9.

Also got 1090km out of our transporter. From Brissy to Campbelltown via Anna Bay.

Neil

[Transporter]

Done now 3000km and average fuel consumption 6.4L @ the pump mainly short trips arround Adelaide. Only used BP diesel.

[GermanwithaVdub]

around town i avg 7.5L/100km in my 07 2.0 tdi golf and thats with the powerchip turned off. admittedly i drive it pretty hard but to tell the truth i'm a little disappointed with the fuel consumption... best ive gotten is 830km which included a trip to canberra doing 120km/h (130 speedo) all the way. btw its got 9k on the clock. maybe its time for an oil change? will that help?

[Soundofav6]

Sorryn Guys couldn't resist.

My vr6 13.5 L/ 100kms lol not very fuel economical in the city highway driving to Penrith I got it down to about 8.2L / 100kms wasn't to bad still the dielsels beat it lol ;)

my thoughts are with you dude.
I am happy to get my vr6 to 10/100.
It may sound sad but I play a game with myself driving from uni to home I try to get below 10L/100 in a 12.5km journey. if i get 9.5 I am over the moon.

One time at 2:30 in the morning no traffic, from city to parramatta on epping rd I got 7.3/ 100.

For all you ppl with TDI out there, just curious, how much is it for a tank. over 1000-1500km/ tank is amazing. Those are astronomical numbers how I see it.

[GermanwithaVdub]

60-70$... think its got a 55L

[GermanwithaVdub]

thanks for that reply. when accelerating hard in first or second gear the real-time calculator gets stuck at 99L/100km (i guess it cant go into triple digits) and that was even before the getting hte powerchip in. speaking of noise, i love the sound my tdi makes... sounds like there's a truck stuck in a refined euro shell hehe. i guess i should be driving more like a grandma to get better figures but its a bit hard when living in sydney :( oh but i just thought of something... at 2000rpm, in lower gears (1st to 4th), wouldnt that give significantly more engine resistance. so im thinking that although the burning of the fuel might be the most efficient as you said, it might have to compensate for the resistance of the engine slowing it down? just a thought...

[gldgti]

good advice... but one thing..

engine braking doesn't improve your fuel economy, and using the brakes wont worsen your fuel economy - EXCEPT where you slow unnecessarily and then need to accelerate again. (infact, the most efficient way to stop, fuel consumption wise, would be to turn off the engine competely, but do not do this, its dangerous). you could roll to a stop in neutral.... but dont, its a bad driving habit. the most efficient way to do this safely is to stay in a high gear and disengage the clutch before the revs go below idle.

the slower you accelerate, the better fuel economy you will have.

the most efficient point to drive your engine at is at peak torque (also peak BMEP for those who understand) (anyone wonder why you get crap economy in a revvy engine with peak torque at 5000 rpm?)

[GermanwithaVdub]

dont worry, my car isnt lacking in the firm acceleration department haha... all that torque in such a small car means the redline is so easy to get to. i think what you're saying with the saving of fuel by using the engine to slow down is that if you do it that way, the speed of the car causes the engine to keep the revs up. when you put on the brake and clutch/neutral, the engine has to start burning fuel to keep the revs up. if his GLD is manual then it would be the same. in fact i would argue any manual car uses less fuel if you use engine braking.

oh you mentioned that they use 0.5L/hr idling... mine uses 0.7! and if i have the heating/aircon on it uses anywhere between 0.8 and 1.1L/hr... whats all that about? i think ill mention it to the guys at the dealership when its first service is due... only a few months away now. and at the moment im running on the the stock wheels/tyres, im painting my other ones black this weekend :D but the fuel figures seem to be un-noticeably similar whether ive got the 225/45 tyres or the 195/65 tyres.

a friend of mine who has the identical car to mine also says he hits that 99L mark fairly easily.

[GermanwithaVdub]

never gotten below 0.7 over the life of the car. and i should clarify that my ecu isnt "chipped" (sorry used the wrong word) i should say powerbox instead of powerchip, i only recently got it, didnt want to get it before the engine had some miles on it. i think im going to take it out ive decided i love my car too much. oh well ill mention it to the blokes at the dealership but then again they're more interested in sales than fixing... or maybe i should mention that i might be thinking of buying a passat for the family that should make them jump to it :D thanks for the help guys - michael.

[smithy010]

Well, here are my preliminary (rough) figures for the blue mountains cruise day yesterday, which is basically the first time i've had the diesel out.
It was pretty hard driving up the mountains, and trying to keep up with all the mk3's and 4s, so i expected it to use a bit of juice, (that, and i still have a fuel injector return line leak), but the figures were somewhere around 5.5l/100...

Was going to fill up and find out exactly how much i used today, but i was out supervising some drilling near campbelltown, and the drillers filled me up out of their fuel cart... Can't turn down an offer for 20l of free fuel..

Pretty good figures considering the driving conditions i'd say.
I was also surprised at how well she pulled up the hills.

Cool

We did a 500klm round trip down south in WA starting in Perth 2 days after taking delivery with 150k on the clock and got 5.6l/100k ... cruise control on 110kph...impressive or what?

[mollins]

My '80 passat with a 1.6TDI gets 6L/100k's at 110-130kmph (highway driving) and about 6.5L/100k's around town. Im sure it would do ~5L/100k's if i didnt drive like an idiot and didnt have the max fuel screw turned right up. Still, pretty awesome for an old car thats usually full of stuff and isn't slow like the 1.5's.

where the hell did you find that mate :o
how does the 1.6Tdi go? BOOST IT UP

[mollins]

how does the 1.6Tdi go? BOOST IT UP

found it in brisbane... had to trek up and pick it up..

1.6TDI is unreal.. already got boost up from 7psi to 13. Im gonna intercool it then do some more injector pump mods.. hoping for 20psi before i need a copper head gasket and stronger studs... then onwards to 30.... :D

ill get round to doing a write up with pics and everything one day when uni isnt so insane

Hey JansJetta,

A couple of weekends ago the wife and I did a roundup trip from Melbourne to Victor Harbor of 1,600 km and got 4.7l/100 with cruise on about 105kph.

And for life of car we've got 6.1l/100. That's on 25,000km with mostly wife driviing in the city. We're impressed too!

What car Jetta do you have?

1.6 turbo diesel.... INDIRECT injection, not TDI - Turbocharged Direct Injection...

just for clarification for when someone goes looking for a 1.6TDI and finds that they dont exist....

[sTeeDi]

For the life of the Car I've been getting 6.5L/100km through mainly city driving, I hope it begins to drop now that I've passed the first two stages of the long run in period for TDIs. I envy you guys getting less than 6.0L/100kms, hope it's just because of my running in of the engine (and maybe my heavy foot) that is causing the high fuel consumption.

I'm still running in my MY07 Comfortline DSG Golf. After finally getting the Dealer to flash the ECU because of my starting problems, what i find is after the flash the car drives a little more smoothly (not sure if its coz of the running in done so far), and i don't have problems crankin' the car anymore.

Will be heading down to Canberra this long weekend with the Olds, and it will be the first time for me to use the Cruise control after getting 7,500km on the clock, of course I'll have to be careful flogging the car due to the double demerits :(

Don't hit yourself over the head with your fuel consumption figures. I've notice that you don't have to do much driving in the city to greatly elevate the thirst. I can go to town (46km round trip) on 4.7L/100km driving on our windy, hilly Tassie country roads as long as I don't drive around while in town. If I have to do some shopping or deliveries that involve a lot of stop-start, then the consumption goes way up. Often it gets to the 5.5L/100km mark. And also it isn't consistent. Today I did a "there-and back" and I got 5.0L/100km.

My old Mk1 uses less fuel in town than it does on the highway!!

Don't hit yourself over the head with your fuel consumption figures.

Hi Brackie,

Don't get me wrong, I know that consumption can vary and be quite different between city and urban cycles.
The thing that really amazes me is how low the consumption can be especially when compared to my other vehicle (2003 Camry V6) that doesn't have the same level of performance. 4.7l/100 for the Jetta vs 8.9l/100 for the Camry on the same round trip to SA and back.
I only use the MFD display as a guide and rely on actual litres at fill against odometer reading. This is done on an EXCEL spreadsheet (Yeah, I know I'm anally retentive!):)
I find that the MFD display can be optimistic by up to 0.5l/100 when compared to my spreadsheet.
Around Melbourne the last fortnight the wife got 5.8 on a tank for 864 k but typically she gets about 6.2 l/100. I get 13.8 from the Camry to and from work.
All the figures I quote are from my you beaut spreadsheet. I use this also to keep the leasing company hones with fuel charges and manage my mileage for FBT purposes so that don't go under 25,000k pa and have to pay extra FBT.

Cheers!

2.0 TDi DSG
Currently on the 5th tank. It has been a mixture of freeway and urban driving. The Jetta now 350k on trip & computer says 680k to go. Have 3500k on clock and comsumption seems to be getting better with each fill.

City driving

Don't hit yourself over the head with your fuel consumption figures.

I also noticed that the road surface makes quite a difference. The smooth bitumen gives a 1L/100klm better return than the rougher blue metal surface (approx 6 v 5), but that would go without saying as the rougher surface would enable better grip and stopping ability.

[dammfool]

Ive got 23thou on my polo,Recently i did a country trip and did 690ks on 31 litres

[Macca]

I was listening to the radio the other day and Will Hagen said that when the fuel usage readout is 0.0 it really is zero. I always thought it would be pretty low - just enough to keep the engine alive while it was engine braking ie less than idle.

When at idle my 2.0TDI ranges between 0.5 to 0.7 L/100k

What do you guys think? Is the fuel usage really zero when engine braking - I always thought some of the "idle" fuel would still be required.

cheers Macca

A friend has been keeping stats since day 1 - May 2006 - when he bought his Polo TDi. Note: consumption really improves after 30,000klm. The first line is the overall average for the 51849 klm to date. The blank lines is where a service was done. Sorry about the allignment. Hope you can work it out.

Just thought I would bump this back to the top to see if someone can answer this.

[gldgti]

Just thought I would bump this back to the top to see if someone can answer this.

and you shall have your answer - albeit an engineering educated diesel head guess.

there is no need for a diesel engine to use any fuel during an engine braking scenario whatsoever. i used to have a manual switch for the fuel solenoid on my old mk1 gld which cut off fuel completely, and not surprisingly, the engine works just the same without any fuel in that situation as if it has idle fuel.

it is very likely that the ecu mappings on the new tdi's allow no fuel though during no load operation/above idle speed because this is a sensible way to reduce fuel consumption. there is no engineering reason why this could not be done.

You made it sound so simple. Thanks.

Have a round trip to work of 40km.@ mostly 100km/h.
Oneway is part down hill. Been getting 5.5 and the other 5.1 :D:D

[smithy010]

Adding to this- if you are saying your engine is doing 0.5-0.7l/100km at idle- is this while stopped?

This would be infite litres/100km if you are doing 0 km/h while it is telling you that...

[Macca]

You're right Smithy.

The readout at standstill is actually L/hr not as I quoted originally

cheers Macca

[homie100968]

I havent let my tank run almost empty till today and the tripmeter indicated 777Km, I filled till it was almost running out the filler neck , 47 liters used so gives an average of 6.04L/100km although the trip #2 indicated 6.7L/100km?? Go figure.. I also noted my GPS tells me the speedo is indicating 106Km/hr at an actual 100Km/hr. I run the aircon 100% of the time set to 22Deg as the 30 something outside is somewhat uncomfortable.
Fuel consumption at standstill is around 1.2L/hr, AC running and 0.9L/hr with it off. Car has 2000Km on the clock. Tinted windows yesterday.. Towbar last week ( Did it my self ) wiring for towbar yet to be completed ( see the thread on the towbar wiring hassles ) So far so good.

[neil]

Filled up for first time today.
954km on one tank, put in 53.1 litres.
I think the tank from memory is 55.

Trip from central coast to Bowral 230km averaged 5.3 and return trip 4.2
(MFD)
Return trip is down hill. no air con and traveling at speeds of 90-110 for
run in period.
Filled up with BP. I suspect the dealer did not use bp as I have not seen
any around there service centre. So will be interesting to see if I can
improve on economy with bp.

[gldgti]

nice numbers - 4.2... hehe

my mk3 economy keeps improving - i've tinkered so that the turbo is always operational (electronic wastegating) and the low rpm timing retard is disabled...

that change alone (after 3 tanks) ahs improved the economy from averaging 6.4l/100km to 5.75l/100km.

[Big Al the Butchers' Pal]

My Golf V 1.6 is used only for travel from Sydney to Hartley, and some occasional running around in Sydney traffic.

I normally get 950km to a tank and 980 on the odd occasion if I travel too far beyond the fuel light turning on.

According to my glovebox manual my tank is 60 litres capacity which equates to 6.3 litres per 100km. I use regular unleaded fuel.

The trick is to keep the revs below 3000 RPM and short shift where possible. The only exception is when screaming up Mt Victoria in 2nd Gear at redline, whilst praying that I do not break a connecting rod in the process.

P.S My car only has a 77mm piston stroke and a stupidly long rod ratio, so revving the freaking bananas out of the engine would not be that bad (I hope).

[GermanwithaVdub]

on the new gt tdi so far - 8L per 100. something tells me that this n umber isnt going to improve much :D

My gues is that your oil consumption will be not noticable - up to 0.75L in 7,500km in just right time for the first oil change.:)
Your fuel consumption is showing that you must enjoy driving it as i do: i can't resist to accelerate fast at every oportunity within the safe speed limits.j:

ah yes... enjoying driving for me is an understatement :) speaking of speed limits, got flashed from the new speed camera at the bottom of mowbray road after swinging round the corner :( took all of what? 4 days to get a speeding fine with the new car j:

[gldgti]

haha - speeding,

after driving mk1's forever, going into my mk3 td, i've really had to train myself not to speed on the f3 between hornsby and gosford every day. its so easy with those ratio's to cruise at 130-140...

they dont... neither do they have 60L fuel tanks

[Big Al the Butchers' Pal]

My car is petrol. In response to your query, I rechecked my technical information as is stated in my car manual (located in the glovebox).

My car seems to be the only model contained within that has a 60 litre capacity fuel tank. The rest have 55 litres. Only the 75kW Petrol Engine has a 60 litre tank according to that technical data sub booklet (part of a number of books contained within the overall black folder).

I re-checked some of my petrol receipts and I have filled more than 55 litres on a number of occasions.

I will ask the Bug_Racer as he is due to do some maintenance checks on my Golf in the near future, but my manual states 60 litres. If my car is in fact 55 litres, then I will correct my consumption calculations accordingly.

For what its worth one of my non VW car's hand book says it has a 68 litre usable tank but on occasions I have been known to put 75 litres in it!

The whole subject of fuel tanks and gauges and their accuracy can be an emotional one. The only way to put it all to rest is drive until the car konks out and refuel to capacity (that's how I found out about the 75 litres above). This is not too good or recommended becuase of the crap picked from the bottom of the tank though.

Sometimes when the low fuel warning on our Jetta comes on I can fill up and only get 47 lt in and other times 53 lt (taking note to fill up asap when the light 1st came on). In the handbook the guide is that the light comes on at about 48 lt. So give or take it's within limits.

Cheers to you all.

[GermanwithaVdub]

thats ok if the book says 60 then its 60 :)

[gregozedobe]

If you are interested in fuel economy (or consumption) there is only one way to calculate it with any accuracy (don't believe your VW MFD, they can be more than 15% out) :

Fill tank to brim, record current odo reading (or set trip meter to zero).
Drive at least 200 km (any less reduces accuracy).
Fill tank to brim. Record how far you have driven it and how many litres you put in.
Divide litres by kms X 100 = fuel consumption in litres per 100km

Some factors that can affect how much (or little) fuel you use are:
City driving uses more, hwy driving uses less (usually).
Faster driving uses more, slower uses less.
Hard acceleration uses more, gentle uses less.
Cold engine uses more, warm engine uses less.
Aircon "on" uses more.
Roof racks with stuff on uses more (wind drag).
Towing uses more (wind drag and weight).
Anticipating lights and stoppages uses less.
Properly inflated tyres use less (as do narrower tyres).
Diesels use less than petrol engines (usually).

I strongly advise against "drafting" (following closely behind another vehicle - too dangerous) or "coasting" (particularly with your engine switched off - that's just plain suicidal).

[neil]

Just done my fuel consumption figures manually.
1st tank. 949km average 5.5/100
2nd 948km average 5.3/100
3rd 1216km average 4.7/100
3rd tank consisted of added 6.5litres $10.00 of fuel from Young servo to get me back to Sydney.
Most of travelling done on Fwy. use of BP fuel and mostly no aircon.
Trip to young is down hill returning to Sydney from the Southern highlands.
My MFD on setting 2 is showing Average of 4.9 which has not been reset
from day 1 of ownership.

[OilBurna]

best 4.9l/100km on a run down to geelong. average mid 7's around town mostly peak hour driving some freeway. hoping to get down to the mid 4's on a longer drive, try that in your prius..

[Preen59]

I'm getting about 5.4l/100km out of the big bad caddy on trips.

It's a little higher around town, depends how you drive it :).

It's got 21 thou on it now, i found it loosened up around 10 thou.

[SteelHand]

My MFD on setting 2 is showing Average of 4.9 which has not been reset

Quick question as I am at work and not near my car manual. How do you reset MFD setting 2 back to zero L/100? - I filled up this morning and couldn't work out how to reset it and as I was running late for work, I couldn't sit at the petrol station reading through the manual :)

It's for a MY08 GTI

Heh, just realised this is in the diesel section - I just did a quick search to get to this thread, hope you don't mind.

[gldgti]

no probs mate, someone here may help you anyway...

...however i can't. anyone with a mk5 able to help?

ey pal welcome. just view in the mfd whatever you wanna reset and then hold the ok button. i like to leave setting 2 alone though so i can get an huge average whenever i look at it and then if im bored ill calculate the fuel usage manually from filling up.
