I've been surfing this site for over 10yrs but finally joined to as some questions. I have a Passat TDI and looking for alternatives to the special oil they recommend. The last two oil changes I've used Rotella T5 and seems to run fine. I went the first 50k miles by the book, but now I don't feel comfortable running 10,000 miles on 4qts of any oil. So I'm going to now do 5k oil changes with the T5.
Anyone have experience with VW Spec alternatives?
