I was considering rotella t6, Mobil 1 0w-40 euro, and German castrol 0w-40. I want something I can get locally and easily and these 3 fit the bill from what I see on the shelves at Walmart and auto parts stores. Any info would be great! As well as opinions! Thanks everyone!
I used many of usual suspects, Mobil 1 0W40, Castrol 0W30 (while it was GC), Castrol 0W40, Pennzoil Ultra 5W40. Now trying Pentosin 5W40 (for different reasons that does not affect your Audi 2.7).
Of all oil, I will still say Castrol 0W30 is best oil for Euro cars, BUT it's price does not justify benefits considering price of Mobil 1 0W40 and Castrol 0W40.
I did UOA of Mobil 1 0W40. It was simply stellar! You cannot go wrong with that oil.
I used once Castrol 0W40, and I think I will go back to that one. It has better start in cold, and engine revs happier then with any other oil I used except 0W30.
Now you said your Audi used 1/2qt in 750 miles. How many miles you have? You might need heavier oil due to mileage. Maybe you should try T6 then.
