Engine oil PENNZOIL or OEM Audi

Use Penzoil Ultra Plat. Can probably stretch it to 5k miles with no issues.

I switched to 5w30 Pennzoil Ultra Platinum a long time ago on my 2.0T. 140k miles and running strong. FK8 CTR Turbo added around 133k, too. FBO PRL mods!

I run Pennzoil or Motul depending on if I grab filters locally (Walmart for Pennz) or buy an oil change kit online (most use Motul). I would have no quarrels running Toyota's oil (Mobil 1), Subaru's Oil (Idemitsu), Valvoline, or any of the other reputable brands in my car

have run penzz plat 5-30 for the entire life of the car almost, recently switched to the high mileage version as im pushing almost 150k miles on it.

i use pennzoil plat every 3k seems to be fine for the past 57k miles

I go every 5k using Pennzoil Platinum 5w-30, though it's just a stock engine/tune and more than half are highway miles

The engine itself runs great with the 48K I put on it in the past 2.5 years with biannual oil changes (Pennzoil Ultra Platinum). Averaging 27 MPGs on 91 Octane hwy miles, 24-25 mpg in the city.

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.

I have a C7 3.0T A6. I put about 2 quarts of oil in it in between oil changes depending on how hard i drive. I don't have a check engine light. The engine doesn't knock, it runs fine.

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
