i know this probably has been discussed a few times, i search and couldn't find any relevant topics.

im having a friend do the oil change at his shop, he carries motul.

i was putting the castrol syntec but i don't trust the dealer with the car, they are idiots. should i stick with the syntec, or is motul a little better?

also, how many quarts it usually takes?
thanks

I like castrol since I can get it almost anywhere I travel.

i usually keep a few quarts of castrol in the trunk.. just figured since that is what he stocks and also heard it's audi certified oil.

i may go to walmart and get a few cases of castrol. oil is oil i guess and i feel like floating my boat.. hit 65 degrees today

I have no idea how you could search this forum on oil and not find anything.

Castrol Syntex is NOT a friend of the RS4 DI engine. That oil is completely exhausted by the 3000-mile mark as documented by oil chemistry analysis of countless data points from all over the country. Castrol is susceptible to fuel dilution which greatly accelerates ring, cylinder wall, and bearing wear. Or perhaps you lease the car, in which case it doesn't matter! At least to you...

Now for the kicker: What you want to use, believe it or not, is vegetable oil!
