Injector clean

[thejack72]

Evening all,

Just a question about injector cleaning duration... had the 45,000 done on the Golf the other day and the dealer suggested I get an injector service done.

I know with petrol engines it's not a bad idea around now but have no idea about diesels.

The dealer was great on the 45,000 service, had a few niggly things which were all taken care of under warranty. It has to go back in a few weeks to fit a gasket that they didn't have in stock & I said I would consider the injector suggestion & might get it done then.

Am I being taken for a bit of a ride, is it too soon? Any thoughts?

Cheers, Jack.

[Buller_Scott]

what kind of ''injector clean'' service? and how much are they charging?

my mechanic (volkspower) simple dumps a bottle of diesel injector cleaner in the tank at every 15k service.. it's $20 bucks.

i'll also put a couple of bottles in between services.

this, and giving it the beans every now and then, should be enough to keep the injectors clean.

[thejack72]

Not really sure what type of clean they are planning... or what is required for a diesel - hence the question here.

Thanks for the reply, Jack.

I use Interject equipment with Interject chemicals to clean the fuel systems it takes 45-60 minutes on TDI and at the same time the fuel filter is replaced. Your dealer would most likely use something similar, basically the engine idles when prescribed amount of chemicals is used.

I don't do it on our diesel cars, since I use additive in the fuel tank 100% of the time.

Hey Transporter .... in anticipation of my 1st VW diesel, what do you add to the tank so I know to get it as well. Did not care about my only other diesel ever, but I do care about the VW ....

[Greg Roles]

I use fuel doctor from supercheap and run bp ultimate with supposed inbuilt cleaners anyhow, if they don't pull them out and ultrasonic them I can't see that it would be any better than routine additives.

Out of curiosity I'm interested in which one you use...

I agree and I'm assuming they ultrasonic clean them as during the conversation he said the injectors are removed from the car. I have used additives but not religiously, I'm going to try and be more diligent from here on.

Thanks to both of you for your replies, Jack.

I use Interject Interjectron (415Y) for petrol engines, I have Interject diagnostic and cleaning equipment (does petrol and diesel, it demagnetize injectors, like it more than ultrasonic).

For diesel engines I use few different additives. My main one for PD engines and without the DPF is Moreys Diesel engine smoke killer, every 6 months I put bottle of WURTH Diesel additive or LiquiMoly SpeedTec Diesel in the tank. In CRD with the DPF I use only WURTH CRD Additive or LM SpeedTec Diesel.

Now, why I don't use Interject as my main additive for CR (or PD) Diesel with the DPF? Interject doesn't state that their diesel additive is safe for DPF, WURTH confirmed to me that their CRD additive is safe to use in CRD with DPF and European dealers across Australia and dealers in Europe are using the WURTH additives, and what is more important; their formula doesn't change in Australia (Made in Germany).

I know in the past there was a need, especially from an agricultural perspective, to use a diesel additive with an anti-algae\fungal property in it every now and then. We used to add it to the 2000L tank every time it was filled on the farm.

But with "ultimate" and "vortex" diesel, is there still a need for this? If using a diesel additive, should it include a biocide?

I can't find enough info on the WURTH Diesel Additive CR to confirm/deny a biocide. But there are a few which include it, but they don't say whether they are safe for DPF use....

You still need to use the diesel additive (even more than before)
I stock the WURTH products (some of them) and WURTH rep. confirmed me that CRD Additive is safe for DPF and they supply majority of the dealers in EU and dealers in OZ that sell European cars. It contains: no sulphur, phosphorus, metals or acids.
I use it in our Touareg from new and have no problems, indeed my daughter that drives it 100% of the time never reported anything unusual that would indicate the DPF regenerating. (I use 2 bottles in tank every oil chnage - 7,500km)

Transporter,

What are your thoughts on "fuel dr" product in comparison with wurth and what advice would you offer to new TDI golf owner about diesel fuel additives.

Where I live we only have caltex vortex diesel. Many thanks

[Transporter]

Fuel Doctor is heaps cheaper compared to Wurth CRD Additive.
I didn't try the Fuel Doctor yet. From what I see in the video they have on their website; it looks and most likely it is a good product. Backed by Castrol, it should be safe to use in CRD with the DPF, Greg is using it in his Golf GT and has no problems with the DPF, it could be worthwhile to try.

[deek]

Sorry to be ignorant, but what does DPF & CRD mean?

CRD - Common Rail Diesel
DPF - Diesel Particulate Filter

IFAIK - As far as I know ;)

I took my GTI in for it's 45k service and had the same line about the injector clean. They wanted an extra $199 !

The best way to void the need for the injector clean service is to use fuel system additive on regular basis, right from the start when the car is new. In case of TSI or any petrol engine I suggest Inter-Ject fuel system cleaner into every 3rd tankful. With the diesels, every time you buy fuel.

My brother is a member of a large Motor Home Club and they buy in bulk a product called MainLube, and they all use it in their Diesel motors homes and im using it in my Navara Diesel and my Golf V gt Diesel ,I was given a 1ltr bottle and ive nearly used half in 6 months and i do notice a more smoother idle in both vehicles. They also make other additives.

I've tried Lucas Fuel Additive; filled up 6 days ago.
Lucas Fuel Treatment : Lucas Oil (http://www.lucasoil.com/products/display_products.sd?catid=2&iid=26)

As per instructions, I put 330ml in the T5’s fuel tank and filled up. I have to admit that the blue smoke from the exhaust on first start up in the morning is completely gone.

The word of caution!
If your diesel has DPF box, I wouldn't use it, since I don't see any note on the product label that it is suitable for vehicles equipped with the DPF. But that's only me, you make your own decision.

I have also just tried a bottle of the Liqui Moly SPEED TEC Diesel whilst I wait for the Wurth products.
I must say it is pretty good! Sells for $20 - $25 at various Supercheap / autObarn retailers.
LIQUI-MOLY Fuel and Oil Treatments & Additives (http://www.liqui-moly.com.au/product3.htm)

Out of interest, has anyone tried the Liqui Moly TOP TEC 4200 5W-30 engine oil?
It has the following approval VW 504.00/507.00.

I am interested in trying it...

Yes, I know they don't have the best website and that link in pdf The assembly professionals is changing every month, so it's hard to quote their specific information. As for Liqui Moly oil, if it has MOS2 in it, it would be probably the best oil for TDI's.

Transporter, as for the Liqui Moly oil and your question around MoS2, here you go; LIQUI-MOLY Fuel and Oil Treatments & Additives (http://www.liqui-moly.com.au/about.htm)

[Transporter]

Yes I know, it is great stuff I'm already using LM Engine Protect (Mos2) in all our rides except Tiguan (still too soon). :)

[ope126]

Did a little more research and contacted Liqui Moly Australia today.

They have advised that they no longer import the Speed Tec Diesel. Only what is available in retail outlets.
After speaking with a rep, they sent me an email with the Technical specs of the Liqui Moly Diesel Anti-Knock Plus. FUEL ADDITIVES (http://www.liqui-moly.com.au/products/fuel-additives/)

According to the spec sheet it is safe to use with DPF's.
This looks more like a cleaner than just a booster of the Speed Tec.

What are your thoughts on the Diesel Anti-Knock Plus?

PM me if you want me to send you the PDF Spec Sheet.
Unfortunatley I am unable to add to this thread.

[ope126]

I have used the Liqui Moly Diesel Anti-Knock Plus; seems all good so far!

[Transporter]

There is LM SpeedTec Diesel (is compatible with DPF) at Super Cheap Auto for $10 per can, normally $20, cause it is discontinued product. :(

Hi Guys,

I just recently put in 70mL of Chemtech "Diesel Power" (instructions say 1mL of fuel additive to every litre of diesel fuel) in with my last Shell diesel fill since we're going to be going for a long trip. Although only had the Passat TDI for just under 3 months (4,000km), has anyone else used this product and are they basically all the same (770g/L liquid hydrocarbons)?

Also, is it a good idea to put some additive into your diesel tank every 3 or 6 months to keep the injectors clean as I used to do this regularly with all my previous petrol cars?

IMO, the Fuel Doctor from Super Cheap is a better product than Chemtech. I use fuel additive every time I buy fuel and recommend the same to my customers with the diesels.

[m3103]

sorry if this has already been answered but my brains mush after work today and all these additives and cleaners being thrown around have done nothing but go in and straight out.
Can someone please tell me a good fuel additive (i.e. to add to every tank) for my mk6 TDI? and where i could get it?
Thanks in advance

[Transporter]

Here is the link, http://www.vwwatercooled.org.au/f28/diesel-city-driving-anyone-54394-2.html#post619836

Just remember that additive must be made for Common rail and also that the majority of the additives coud be used all the time you just use less of it.

[T5Pete]

If I was going to add $20 worth of additive to my tank every fill up or make a claim that a product like this is really good I'd want some pretty conclusive proof that it even did anything. How are you guys noticing the difference? seat of the pants bum dyno? I'd want to see a before and after dyno run and fuel consumption figures to see that this stuff does anything at all.

[FarQ]

Ok, so whilst being a little confused, I have worked out my 06 Polo TDI does not have a DPF. So what is a recommended injector cleaner additive for my car? I change my oil every 7500km.

Try Lucas Upper Cylinder Lubricant and Injector Cleaner or Morey's Diesel Engine Smoke Killer. I use both.

at the same time? what sort of intervals?

[Transporter]

at the same time? what sort of intervals?

No, randomly and always when refueling. It means, I never bought the fuel without adding the additive in my T5.

[FarQ]

So I can go to supercheap auto to buy this stuff? Also since i don't have a DPF, is this still economically viable per tank fill? Does this have an effect on the EGR (I assume my polo tdi has this). Sorry for n00b questions :)

Motormate would be probably cheaper to buy it from, at least here in SA. It is economical to use but I recommend that you start with Lucas and read the instructions first use 1/3 of the bottle for initial clean and than as the label suggest.

Yes, it is good for the EGR.

What about flashlube?

I've never tried it. Does it say on the label that it is the injector cleaner for the diesel?

FlashLube Diesel Fuel Conditioner (http://www.flashlube.com/en/products/diesel-fuel-conditioner.html) Australian Made & Owned! :) Dunno about whether it has any effect on DPF's and other diesel what nots....

[FarQ]

sent an email to FlashLube about whether their product is safe for CRD and DPF.

[monkeysrus]

Anyone ever use Redline 85 diesel fuel additive?

[TDI DSG]

A question for those using fuel doctor - did you do the shock treatment ?

If so how many klm's did you have up before starting to use it ?

[Greg Roles]

Yep, every 7000kms or so. Not much point till say 15000k, need some dirt to move!

[poyta]

A question for those using fuel doctor - did you do the shock treatment ?

If so how many klm's did you have up before starting to use it ?

I had about 40,000kms on mine when I first used fuelDoctor - did the shock treatment, now its 25ml every tank.

[TDI DSG]

Thanks for the feedback guys !

Did you use the full 250 mls( think that was the amount - dont have the bottle in front of me now) in your VW tanks being that they are mostly around the 50 ltr capacity ?

I want to use it in my CRD Rodeo first. This has around 50K on it currently. Not sure about using it in the new 103 TDI we have just picked up - it isnt through it's second tank of diesel yet. I've not found anything to say if fuel doctor is safe for use with DPF's yet.

[Greg Roles]

I throw a whole bottle in approx every 7000kms. The idea is to "shock" the system and prevent any algae forming - unlikely in BP ultimate fuel, but you never know.

Fuel doctor will be a lot less of a problem to your DPF than the stock amount of oil blowby it ingests on a daily basis.
