Engine oil OEM BMW or OEM Audi

i drive a g21 330D xdrive, I've been researching warm up procedures and people recommend letting the oil circulate for 30+ seconds then cruising in eco pro as the torque band is toned down and it changes gears as early as possible.

Depend on the oil grade that is in the engine.

In proper units that’s -15°C which is very close to the limit of a 10W- oil. I would let such car warm for 5 minutes easily.

If your car is running a 5w or 0w it will be fine to start driving in less than a minute. Which is just the time you need to remove the snow and ice from the windows, how convenient :P

I do in my BMW. Oil is cheap compared to a re and re on a diesel no longer sold in country.

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.

bmw oem 5w30. n ai cum sa dai gres.

I always buy OEM oil from dealer and then get it done at the shop or do it my self sometimes. Just prefer that way cuz I care way too much.

Ive been using 5w40 for 100k miles and my engine is happy as can be. It actually is noticeably smoother with thicker weight

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.

I do this on my Q5, I started using like half a quart of cheap new sacrificial oil to mix up the bottom of the pan and extract as much black oil as possible. I almost had an issue with the extractor tube getting stuck in the engine l, but I was able to get it out with a bit of force

Had a Q5 and it was a money pit. Oil Consumption got so bad I was putting in a quart every 400 miles.
