Engine oil Mannol or OEM Audi

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 run the 5w-40 in my 2004 Audi A8 and both of my power strokes just because it's handy and the diesel grade oil is overall better than the other synthetic I was running in a 0w-40 weight.

Genuinely speaking, it's actually not bad oil at all. Apparently manufactured in Germany, meets or exceeds the OEM spec for my cars. In my 350Z which likes to drink oil, I change it using Fuchs Titan Race Pro S 5W-40 but I keep a bottle of this (also 5W-40) in the boot for top ups.

I run Mannol 5w30 for Japanese brands on my 202k km d16

Works fine but I might change to a slightly thicker one

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

Von der Marke Mannol würde ich Abstand halten, da gab es gerade in letzter Zeit [Ungereimtheiten](https://oil-club.de/index.php?thread/3702-mannol-hersteller-thread/&pageNo=19)
