Your owners manual will tell you the = minimum oil required by the TDI. The Mobil 1 15-50 will work fine. That engine = had something else wrong. Extreme oil thickening can also be caused by = antifreeze contamination. There should not be enough soot getting = into the oil to begin with to thicken the oil. Also, what was the filter = doing? Clogging and bypassing dirty oil? Also how hot was the oil = getting? Even with water temps kept normal, oil temp can run away, particularly = with miss-applied engines.

Subject: Diesel Oil again!

Here we go again,

I agree that Delvac 1 is the best synthetic for = my Passat TDI. Unfortunately, it is too expensive and hard to get, so I = use Mobil 1. Now, I am starting to hear that Mobil 1 15W-50 full = synthetic is also not good enough because of soot removal properties! I = know that CF is not as high as CH, but I thought it was still good enough = for a TDI! Even Shell Rotella T dino oil is only CF, right? So = what's the real story here? (I change every 5K miles).

Thanks,

Michael Townsend

P.S. I have put Rotella T in my gas 2.1L = Waterboxer before, because it is SJ or something like that. I wonder if = there is any huge reason to not do that?

Dear Karl,

Mobil = 1 is NOT rated for use with modern Diesels. For that I believe you = need an oil rated CH-4 or better. Mobil Delvac 1 is the way to go (also = good is Amsoil). You can find a lot of info about this on the TDI forums = at:

http://www.ufies.org/~fred/forums.html

also = try another excellent Diesel forum = at:
