i'm going to try it.... i wonder if it makes much difference if you add it to biodiesel

What do you reckon peeps?

I'd be be a bit cautious if your TDI has a DPF - they are very expensive to replace. VW go to all the trouble of only approving special low-SAPS engine oil in case burnt engine oils contaminate the DPF.

I read as far as page 6, and there was not one single flame post - that's amazing when it can be regrded as a "contentious" issue.

There is no doubting the lubricity and combustibility of 2 stroke oil - the Rotaxs on our karts pulled 14,000rpm all year on a 50:1 mixture, and the wear was negligible as was the soot inside the combustion chamber.

I have no doubts that it can replace the lubricity of sulphur in diesel fuel.

YF's observations about the cleanliness of turbos, etc, makes me idly ponder if adding maybe a 1:500 or 1:1000 mix into the GTI's fuel would keep the air inlets cleaner - they do gather plenty of oil and clog the insides of head ports much faster than a port injected engine.

I don't think I'll try it, since it's hard to measure any effectiveness in the GTI engine, but if I had a diesel I would definitely check it out.

There was plenty of commentary about that issue in the small amount I read. YF is specific about the ash content of the 2-T oil recommended, and specifically says not to use fully synthetic in a DPF vehicle because it does what you are fearing.

Yeah I'm a bit leery of doing anything to upset the DPF. Although the woman (!!!!) who started the thread and recommends adding the oil, is firmly of the opinion that it won't harm the DPF and is in fact protective of it - a cleaner burn leading to less soot in the exhaust.

F'ing great find, I'm excited about the idea. Bit of research needed, as indeed oil ash clogs that damn DPF, but as soon as I can find a low ash 2 stroke mix, it's in.

I'm going to Melbourne tomorrow. Got litres and litres of Castrol R30 at the workshop. I'll throw 300mls in before i leave and see how it goes. I'll also take the bottle with me and fill up on the way home.

I usually get mid 5's there and back. It'll be interesting to see what difference it makes.

Report on Monday night.

Edit: I'm going to use Yamalube as we've got a stack that we'll never use. We tried in in the Karts and there was a definite performance gain in it initially, but the longer you used it, the slower the engine became. This turned out to be because it was actually de-carboning the engine. Removing it from the piston crown and down the sides. This caused more heat soak in the engine and gave less piston seal, which equated to a hotter, slower engine. (Talking air cooleds here...)

For this application, it should be perfect. The idea is to lubricate and clean, which this stuff does an amazing job of. Anyways, like i said.. I'll get back to you.
