Thread: 2 stroke oil added to fuel tank(diesel)

Ok.....

First up, it wasn't sulphur that gave diesel it's lubricity, it was certain aromatic compounds that tend to be removed in the process that removes the sulphur.
Sulphur's a nasty substance in the form it's in diesel fuel.

Secondly, lubricant is added to Oz spec diesel so that it at least has the lubricity of the old fuel.
It's measured by scar test, as stated in the Oz fuel standard.

If you want to add some two stroke, i'd advise to use a really good synthetic one that meets the JASO FC specification.
At least then you'll know that it burns cleanly.

People often claim performance improvements with adding two stroke.
I strongly feel that's a placebo effect.
I've used it, recorded mileage and done hill tests and couldn't note any differences.

I also trialed it using good synthetic 2 stroke that I use in my bikes and did not notice any effect at all.

This has been covered a few times here before.

Likewise, I tried it for about 12 months, and noticed no difference what-so-ever.

I am hesitant to call it a placebo effect for those people that do actually see a measureable difference. I tend to think that it maybe the difference in each engine.

Some people swear by it, others less so. In short, if you want to try it, use a good quality oil, add it at the servo before you fill up, and give it a go. From memory, I used to add 300ml to a tankfull.

I add approx 300ml per tank of non synth 2 stroke per 100 litres diesel, have been doing for about 5 years.

It made a huge difference to my 1979 BJ40 3 litre diesel Toyota , both at reducing smoke & generally running smoother & starting easier, Also noticeably smoother in my 80 series & made to over 540,000klm & still ran like new.

I still use it in my TD5 but I don't notice any difference with or without it, but knowing how good it was in the Toyotas I still use it in the Landy.

Thanks for the feedback everyone.

Think I'll give it a miss,have just turned over 340 thou and its still running nicely.

cheers

Its nice to see another overstressed undersize Tdi clocking up big miles without an issue. Pat

make sure you mix it at 32-1 and adjust your high and low speed jets to suit......it should still 4 stroke at WOT

given enough time and luck, you will eventually find a needle in a hay stack...........
