Engine oil LIQUI MOLY or OEM Audi

Liqui-Moly dropped my oil temp about 15F on the Accessport, but I have never seen sub-200 on a turbo car.

I switched to LiquiMoly 5 years ago. I use Leichtlauf in my MKIII. LiquiMoly is awesome! And it's made in Germany.

I've been using Leichtlauf High Tech and its been working great, Just make sure it has the right approval and change it every 5k miles.

I run liqui moly 2040 in my m97 engine. According to my indie shop it performa better than the mobile 1 oem oil at high temps.

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.
