Just had a chap in the shop who runs a vw transporter 2.5 PD and he says theres a 'thing' going around on VW forums about people using cheap 2 stroke oil as a additive too lubricate the pump and help reduce smoke etc etc, must admit just looked at his from 'start up' and didnt give any smoke out at all! its not something ive heard before but have any of you guys?

I vaguely remember reading something along these lines a while ago. The oil is added in very small quantities - not at the level you would use in a 2 stroke engine.

I can see how it would lubricate the system but reduced smoke? 2 Stroke engines are all but unobtainable now because of the particulate (ie smoke) emissions. Certainly when I had 2 stroke bikes, the exhaust insides got pretty oily and they smoked a bit when I gave 'em plenty of throttle. Can't bear to think what it could do to a DPF even in small quantities!

just found a couple of threads odd google - http://www.seatcupra.net/forums/showthread.php?t=230426

must admit havent read the latter yet but could be good reading! not sure im convinced though........

This was discussed in great detail a few years back. The theory is that with low sulphur diesel some of the lubrication properties are lost. Some of the claims made about it's effectiveness were laughable, but some made sense. If you do use it, it has to be low ash 2 stroke oil. Skoda will void the engine warranty if they detect it in a car under warranty.

I've had my '54 plate vRS for a little bit short of 3 years. For most of that time, I've been running 220ml of JASO FD two stroke oil per tank. As Moggy says, some of the claims made for it are laughable, but I've been pleased with the results. At one stage I was unable to get the 2T that I normally use, and ended up not using it for 3 or 4 tanks (wasn't prepared to pay the Halfords price for inferior oil). I notieced an imediate improvement in smoothness and a decrease in smoke (not that mine smokes much anyway...) once I got a new supply of 2T.

From my point of view, the improved response and decrease in smoke levels make it worth the trouble and expense.

Since your VW PD engine doesn't even have a pump to lubricate I fail to see what difference it can possibly make.

Most of the references refer to purported benefits for older tech diesels after all.

Have read it quietens down the injectors.

Just goes to show you can NEVER have too much lube!

Not exactly. The original claim was that high sulphur diesel provides a good deal of top end lubrication, which is missing with the low emission, low sulphur diesel. The 2T helps lubricate the top end of the engine. As to older tech diesels, thats not exactly the case either - there were a number of reported failures in modern diesels due to lack of top end lubrication. The only reported problems with 2T were on cars with DPFs, which doesn't apply to Fabia 1s. For those cases, an ultra low ash 2T is recommended.

2T also improves the cetane rating of the fuel, or so its claimed. Also claimed to help keep the injectors/turbo free of crud - don't know if that has ever been verified either.

Never noticed any real difference in fuel economy (changing front tires from Michelin to Kumos did more to damange my fuel economy than running 3 or 4 tanks without 2T), but the difference in smothness and noise is certainly there....

What exactly is 'top end lubrication' please?

100 miles in

1. Less smoke

2. Quieter

3. Feels more refined

Can tell on the MPG as yet due to crap weather conditions.

which 2stroke are u using?

so far I've found oil which is 'JASON FB' spec - is that ok to use?

will have to look tmr its castrol 2t thou

A very good spec 2 stroke is available from screw fix made by ryobi for there chainsaws. Ive used it in our scooter for years. Its very good value and I emailed ryobi to ask for the spec at first, they rang me back and told me they buy it from shell and it meets the highest spec available as they dont want their tools coming back for repair.

As usual because its for agricultural use ie. chainsaws, strimmers etc. its cheap.

I put 200ml of Motul 710 in and the car run's Very Very well, i use a fair bit in my trials bike and swear by Motul, However it's not cheap so I'm going to get 1l of Repsol from sxs (£7) and give it a proper test.
