Engine oil Mobil or OEM Audi

I own a 2019 N and have used mobile 1 synthetic 0W-30, subs i bought it. this will be my 5th oil change as i change mine every 8000 miles. So far no problems.

I used mobile 1 for the rav 4. Factory fill on the evo was mobile 1

i used the original oil (0w20) but here in mexico is a little expensive. change the oil to mobil 10w30 full synthetic and works great on my fit 2010.

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 have an 07 Rabbit with the same 2.5L. I tried Mobil 0W40 one winter. It was OK for about the first 6000 KM, then the engine began to sound like a diesel.
