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:

    also try another excellent Diesel forum at:

    Cheers,
