Adding 2 stroke oil to fuel - Interesting reading!!

[Greg Roles]

OK guys, have done a stack of research, and it seems 2 stroke is great in helping older diesels cope with the lower sulphur diesel of today. If you run some bio, there's no benefit. Seems to be too many people warning against using it in cars designed for ULSD, and those reporting more smoke, hence DPF cars are out of the question in my mind.

If it gave a measurable power hike, I'd risk it, but it doesn't, so I won't.

I did learn a lot about cetane in the process, and the waste of time cetane improvers are, especially in summer, when they just help diesels preignite even more, and LOWER power outputs. You want higher cetane in winter, lower in summer. Interesting!

Also got to see a lot of yankie dyno charts with various diesel additives, and most of them also lowered power outputs, when a dyno was done in a car with dual fuel tanks, and switched across for consecutive runs, one with the additive.

I won't be buying any for anything other than the odd flush.

But that's my point. If MB uses the technique to turn crap fuel into good fuel (ie, hugely beneficial), how can the technique be harmful?

And if it's demonstrably beneficial, how does that make it harmful?

Many of the naysayers above might like to think about why MB would use this technique and find it rewarding, when they say things like "I'm not an engineer, but......" and refute the findings of engineers.

That's where I don't quite believe what Ms Y? was saying. All her references were heresay or commercial in confidence or unfinished university studies. It started to wear thing after a while.

I don't believe they did.

They organised there own fuel tankers for the relibility run & supposedly/secretly added 2 stroke.

What do you reckon about YFs claims that it actually lowers the amount of soot in the exhaust? As far as I can see, she's the only one advocating it's use in DPF cars for this reason. And she claims to have had her car measured and it produced less soot than expected...

I saw some of that stuff about cetane too, very interesting. Particularly as people seem to regards it like octane and that bigger is better.

sp preeny, how'd the caddy go?

Poked a rod out on the Hume....


NAAAHHHH haha.


Went well. I'd say the 3-5% increase in fuel economy is plausible. I got 5.2 on the way down and 5.3 coming home. Last time i got around 5.4-5.5. This was sitting on 110/100 depending on the speed limit for most of the way, too. I Didn't speed, but i didn't muck around, either.

It's quieter. Slightly smoother. Idles quieter i think. Seems to have a little bit more go in the mid/top end, nothing earth shattering though. Don't know about the soot thing because i can't really see it.

Definitely no worse. The Yamalube worked quite well. I used a bit too much, but i can't see the harm in using more than required..

well there ya go... cant hurt

[GoLfMan]

might give it a crack then

Yeah. Considering that diesels effectively burn high grade heating oil, I figured it couldn't do and serious damage. Especially having experience with the properties of 2 stroke oils. I say give it a go for sure.
