Engine oil Kendall or OEM Audi

I use full synthetic kendall and it runs beautifully.

I don’t drive my car enough to hit any of the reasonable mileage points. I change my oil yearly, roughly around the time it gets inspected. Might be overkill (last year the car moved 2k miles, the year before was 2.4k), but I figure the $80-85 I pay is worth it. My wife’s Q7 will be getting its oil changed every 5k miles. It’s a 3.0T supercharged and they love to eat oil, I’d probably add half the oil back just to make it to 10k.

I do every 5k (2013 S4)

Over here in Germany changing your oil every 3k miles in a normal A4 absolutely tanks your resale value. The only reason to do this frequent oil changes is to hide problems. Personally my car did 30 000km(~20k miles) until 91 000km and then every 15 000km(~10k miles). It's a diesel and almost all longish distance highway trips.

I do 5k/3 months. 3 months usually comes first.

In Canada Audi recommends oil changes ever 15,000km. I always do 10-12,000km because I do city driving. My buddy did every 25,000km on his Mercedes Benz and the thing lasted to 400,000km.

5-6k. It depends on how much you push the car. Hard acceleration and high revs will require more frequent oil changes.

I just change it every 3k as a maintenance think no one told me to. I'm just afraid of messing up my turbo if I waited to long.

2012 3.0tfsi turned out to be a mild hybrid as it burns 1l/5k km.

Why do Audi’s burn through so much oil? One thing I don’t miss about my 2019 Q7 is the constant adding quarters of oil throughout the year.
