Owner reviews for engine oil

I use Shell Rotella T6 5w-40. Available at Walmart lol.

I've been using Mobil1 in my car for three years because the garage I worked at had a contract with their local distributor, and that's what I got at a steep discount. Last year I put Total's equivalent oil in it, absolutely no discernible diffrence between the two.

On my M135i F21 LCI, I always let the initial cold-start finish until the idle drops and then start driving while not going above 4.000 for the first ca. 5km and not giving full gas until the engine oil temperature is 72c or more.

Been doing that and till now no issues or leaks, the engine is running sweet.

I do a 5K oil change interval. I let it warm up for 5+ minutes every morning. Not necessarily because I'm intending to warm it up to operating temp but because that's just how my morning routine goes. I drive moderately and keep the RPM's below 3K and try to keep below 50% load on the engine, aka drive moderately.

Any oil that carries the BMW LL-01 approval should do the trick.

I’ve used German Castrol(aka Castrol Syntec 0W-40 made in Germany) or Liqui-Moly Leichtlauf 5W-40 in my old 650i with no issues.

My Honda CR-Z manual says to use 0W20 oil for best performance and longevity so I follow that advice.

When it comes to oil, Ravenol is really good and is also Made in Germany, some even recommend it over VW or BorgWarner, as it is full synthetic and does not break down/sludge up as fast.

my switched his n55 to liqui from bmw dealer oil and he said it runs wayyy better and quieter.

Currently using Castrol Edge 5w-40 fully synthetic, previously was using Estremo Heatpro 5w-40 FS, differences is so minimal to the point where you just neglect and forget about it....

Smoothness the same, silky smooth.

Car feels slightly like just slightly lighter on pickup with Castrol.

I used the middle one on an old 200,000KM Porsche Cayman S that was burning oil. It made it worse, smoke started coming out of the engine when the oil cap was off and I felt like the engine would soon die.
