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.
Owner reviews for engine oil
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.
Used this for years in my 4 strokes. Quality oil.
As long as you’re not mixing fuel with it you’ll be fine. All of my stuff runs on basic and cheap T4 Rotella 15w-40. Have never had a single issue
Any 0w-20 from a reputable brand will work. I use Liqui Moly, 0 issues.
I’ve used Castro Euro 5w-40 in my ‘15 MK6… got too expensive and switched to STP 5w-40 Euro. Working just fine so far
I've been using liqui moly and never had any issues. The oil itself remains cleaner for longer
Liqui Molly by far every other oil causes ticking noise
