Engine oil Mobil or OEM BMW

For my Z with 210k miles i switched to the one your holding and it burns less. I get an extra 150 to 200 extra miles compared to mobile 1.

I always use full synthetic Mobil 1 5W-30

There was a dude on YouTube that did a test. Mobil 1 performed the best, followed very closely by Amazon basics

Man, just changed out the oil in my 2000 Crown Victoria Police interceptor yesterday with this. I HAVE USED THIS VERY OIL for close to 20 years. My shit runs as good as it has since I first drove it out of the Orange count sheriff's dept, Parole dept. auction lot. Never use anything else.

When it comes to brands most good brands work fine like Mobil 1, Castrol, Valvoline and so on. All these oils even including the cheaper amazon brand oils have been tested by the American petroleum institute and they have a stamp on every bottle.

Since then, I've changed my oil to a low SAPS VW 504 Mobil 1 5w30 ESP X3 which according to lubrizol has superior resistance to deposit and sludge formation. At this point, I've got consumption down to around 1qt/1400 mi which is a great improvement from where it was before. Hoping for further improvements with time but pleased with progress.

I’m slowly switching to Mobil1 since I started doing oil analysis.

It has no sodium and therefore a good way to see if there is a coolant leak.

I've used Mobil 1 in my 2011 Mazda Speed3 for 8 years. My 2019 Bullitt gets Mobil 1 as well. Mobil 1 is reasonably priced and meets the spec required by both cars.

I have ran mobil 1 0w-40 for a long time without issue but am thinking of switching to thicker this change as it's starting to leak out one of the oil seals into compressor housing.

I tried Mobil 1 15w-50 for about 15 minutes (literally!) in my 2.0 one time. The valve noise at startup was so bad I drained it immediately.
