Diesel fuel additives

[Jaymz]

Guys i have read a few threads on tdiclub and it is common for those guys to use additives in the fuel for different reasons. Most would appear to be for better economy, but there is also some there using them for power.

Has anyone used anything here?
Please post up what brand and what results you got.

Cheers,
Jamie

[Jaymz]

Has no one ever used anything?

[Greg Roles]

I was looking at some yesterday at the servo too mate, what with the dyno upcoming and all :D

Seems to just clean out dirty motors, thus restoring power to standard.

I don't think we have a K104 additive option!:D

[neil]

Been reading the tdiclub as well.
Have plenty of threads regarding improving fuel efficiency and additives.
Have not come across any additives over here like they have, but still searching.
The best improvement still seems to be... to take the foot off accelerator.

[Jaymz]

Dam shame, might have to give her a squirt of propane:Dj:

[tezza]

Yes I too have been looking these additives and have come accross the following;

BiTron

Flashlube
http://www.flashlube.com.au/en/dieselfuelconditioner/index.html

Also considering....
http://www.morison.com.au/

My problem is, OK I would def use the Morison fuel filter but do I also use both the Bitron and the Flashlube ????? :?

Try Moreys "Diesel fuel smoke killer".

AMSOIL Cetane Booster

You can get these in AU.
Cheers.

Thanks guys, that's awesome. How cheap is that Flashlube $3.25 per tank and claims economy gains up to 6.5%. 6.5% in our late models diesels is hard to believe but at that price any gain is dam cheap.

I suppose you would have to weigh it up, would you get further on $3 worth of fuel?
I really wonder if there is any performance gains:confused: might be worth a shot though at that price

Of those I understand only Amsoil and Morey's make cetane improvment claims. Performance benefits from them all arise presumably because of injector cleaning capacity. Cetane improvement should reduce engine noise.

Morey's contains a biocide, which sounds like a good idea to use periodically at least.

Given that VW brochures specify 51CN diesel for newer engines and tha standard diesel does not always meet 51CN (since it is made to minimum 46CN per the diesel fuel standard), perhaps more people should be routinely using cetane improvers.

Perhaps someone running an engine where 51CN is recommended should ask VW for an official response.

Gday.
Diesel fuel additives like Chemtec diesel power or the diesel doctor are great for killing algae and dispersing water in the fuel and it also acts as an upper cylinder lubricant when used in low sulphur fuel. I have used them in my truck and my Nissan patrol and I never had an issue with blocked filters or water in the fuel. Cheers.

I've used many different diesel fuel additives and only one lived to its name,
"Diesel Engine Smoke Killer" by Moreys.

Here is another one I forgot to mention I've used it for long time in my MB Vito 108 CDI and 112 CDI. I never saw any smoke behind me in the mirror. May be that’s why I noticed it when I swapped for VW T5. It was embarrassing to accelerate a bit faster from traffic lights. I didn't use anything in the fuel at the beginning. Old friend of mine reminded me the product, which is Pro-Ma DT5plus. Link to their site:

http://www.pro-masystems.com.au/proma_ProductMoreInfo/tabid/103/ID/407/MenuID/84/Default.aspx?returnURL=http%3a//www.pro-masystems.com.au/Default.aspx%3fTabId%3d86

If it happens that you would look at their other performance product I've a good experience with DT5 Plus, MBL8, MBL3, Puncture sealant, Waterless car wash Maxi clean and their grease, which I'm still using. I wouldn't use their PT5 plus (judging from my customers feed back which is 4 years old when I stopped using their products except the grease.
I will try their DT5 Plus diesl additive again in VW diesels and post a comment.

Apparently those in tank fuel thingos make a difference. They stop the engine blacking the oil too from what i've seen, so they obviously improve the charge burn....


I've got some 100% CH3NO2 if anyone's game enough to try that as an additive.. :biggrin:

Bloody hell Preeny, first you're into Racism now it's Terrorism, what are you up to ! :biggrin:

[Greg Roles]

Ready to go, anytime you want to sell me a few litres. Could be interesting at the post office. I will come bail you out though mate, never fear.

An energy drink for your diesel engine.
These could be worthwhile to test, so I bought them at Supercheap Auto today on sale with 20% off strore wide.

http://www.liqui-moly.com.au/product3.htm

Could also be used for fast Vans.

Curious to know how you go. I have been watching smoke out the back in headlights behind at night using BP Ultimate. (Now I have to go back to standard + Morey's smoke killer to see if there is a difference.)

I understand LiquiMoly has an very good reputation. Looking at the ingredients in MSDS (MSDS is a good place to look for clues when the packaging is sometimes bare of ingredients lists.) I also recall a high price per tank when I was looking at them on the shelf months ago...

Speed Tec Diesel ("more than a cetane booster") has:
Naphtha (petroleum), hydrodesulfurized heavy 60 - 100%
Solvent naphtha (petroleum), heavy arom. 10 - 30%
Polyolefin polyamine succinimide 1 - 10%
Fatty acid alkanolamine, polyol 1 - 5%
Benzene, mono-C4-9-alkyl derivs. 1 - 5%

Other diesel products http://www.liqui-moly.com.au/product3.htm below.

Anti-Knock Plus (reduces clatter and increases cetane - how it does the first other than by the second is unclear; has nitrate cetane improver)
Naphtha (petroleum), hydrodesulfurized heavy 60 - 100%
2-Ethylhexyl Nitrate 10 - 30%
Solvent naphtha (petroleum), heavy arom. 1 - 3%

Diesel Purge plus:
Naphtha (petroleum), hydrodesulfurized heavy 60 - 100%
2-Ethylhexyl Nitrate 3 - 10%
Benzene, mono-c4-9-alkyl derivs. 0.1 - 1%

anybody with a phd in chemistry can tell us what they do lol?

Sweet! PM me your address. Haha.

Ohh come on, Russ.. We haven't set fire to anything so far! :biggrin:





I'm tempted to try that additive. Hmmm. Would like to know a bit more about it first though.

I use Moreys Diesel Smoke Killer every time I fill up. It works for me.
I bought:
Moly Speed Tec Diesel to see if it really improves acceleration and improves consumption.
Anti-Knock Plus to see, if it does anything better than Moreys Diesel smoke killer. I will put the Anti-Knock Plus in the fuel next week and post the comment when I use the tank.:)

The Speed Tec Diesel seems to improve diesel economy and cut back visible smoke. I refueled today with BP Ultimate from a bit over a 1/2 tank - 9.35L/100km.

[Greg Roles]

Blah, blah, blah, what about the POWER???:biggrin:

[Transporter]

Blah, blah, blah, what about the POWER???:biggrin:

:biggrin: Better than the ECU re-flash. :biggrin:
It feels a little bit quicker of the marks I would say. Also can drive in 6th gear at the lower speed and feels more torque in 5th gear.
It needs to be taken to racetrack as the instruction on the bottle suggests. I have no time for that.

Just a word of caution guys,

Your diesel is the only thing that lubricates your fuel injection system. If I were you I'd be checking the lubricity (oiliness) of any product I put in my tank. Rub some on your fingers. If it is like petrol or thinners then you may be prematurely wearing out your fuel pump / injectors as it will offer very little in the way of lubrication.

Personally, I think there is no substitute for 100% good quality diesel. The only time I'd be putting anything else in my tank would be if I had algae in there.

Just my 2 cents worth.

Any diesel smoke will show up 10 times worse when you look in the mirror at night and have someone else's headlights shining at you. What does it look like in the daytime? That's the true test.

That would be too late mate.:biggrin:
