I have an 2007 A4 2.0T base. I bought the car with 120k miles on it in 02/19. Yesterday I hit the 224k miles on it. She's my daily driver, over the years I have changed/did the engine oil every 4k miles, car filters all over, wheel alignment, tires, brake pads, rotors, and the battery. Nock on the wood, my baby have been taking car of me. I'm actually surprised that this model is solid af.

Pros: model is solid af

Vehicle: Audi A4

Mileage: 360000 km

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

Pros: more power, better mileage

Cons: car did not like gears

Vehicle: Volkswagen Scirocco

Ran Redline 5w40 when it became purely a summer car in ~2013. ... Not seals are leaking, no issues of any form. Car has been Cobb stage 2 91oct tuned (OTS, not pro-tuned) almost 14 years, with a Crawford v2 AOS, Killer B oil pickup + windage tray being the only reliability mods, and it doesn't burn a single molecule of oil.

Pros: no leaks, no issues, no oil consumption

Vehicle: Subaru
