Engine oil Shell or OEM BMW

I run rotella T6 5w-40. Have for 120k miles and will for the next 120k

I've been running cheap Rotella T6 for 20 years with modified STIs, zero issues.

I use Rotella T4 on my 2.5L and have been for years because high ZDDP helps with the valve tapping I have going on. It has actually gotten quieter over time and feel the engine is running smoother than ever.

A lot of people are essentially saying "don't beat on it until that gauge reads warm," which is incorrect. BMW, in the G series, switched to showing *coolant* temperature on the speedo and not oil temperature. That is NOT the oil temperature gauge, and oil takes a lot longer to heat up than coolant. When that gauge shows operating temperature, give the car another 10 minutes or so to get the *oil* up to temp.

Just drive it. With these 0w20 oil is circulated immediately. My G20 330e does a cold start when accelerating the highway. The RPM limit is protecting your engine so even with a kickdown it won't go above 4k RPM and will shift very early.

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.

I’m using the 0w16 from Renault that probably is a Shell RN17, I have about 25.000km now and I will do the third change on the beginning of next year… but in the sandero that I also own I changed to 5w30 (from 0w20) both RN17 and the engine feels way softer and silent…

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

Rotella T6 5w40 in my EJ255, its helped a tad with the leaking until I can get everything apart to seal it all up again.

Oil leak. Thats my G20, had to fill like 3 times oil myself during 30 000 km. Went to service and apparently they found two separate oil leaks
