The TDI's don't have the sludge problem, that's why you can go 10k. The 1.8T's develop a lot more heat, that's a large part of their problem. Yes, a synthetic will be more resistant to coking, and that's part of the solution. Proper cooldwon is also key. As for cooldown, you can always get a turbo timer. Ironically, while writing this email, I got a call from a guy traveling with oil pressure issues in his A4 1.8T. Go figure!! Tony ----- Original Message ----- Subject: Re: [Vwdiesel] vw turbo recall? 1.8T Thanks for the correction about water cooling. I don't want to start an argument, but 10k changes on a TDI with proper oil don't seem to be an issue. Oil analyses after 10k typically come back as OK for continued service. And of course some people would disagree that the factory "synthetic" is really synthetic at all... it makes me wonder if a run exclusively on a true group IV synth (or whatever it's called) would still have the sludging issue. It certainly should be more resistant to coking due to heat. I sure am glad to not have to worry about turbo cooldown on my TDI - I used to have a Mitsu Galant VR4 and worrying about cooldown all the time was a PITA.
