F95 BMW 2021 X5M Best Oil

[G80_Rob]

How long are you running it so far?
My cars are tuned and compared to some test I've seen of Pennzoil under stress it didn't stay as strong as the Amsoil.
I monitor my cars oil temperature in the dashboard but also in my datalogger, my F90 M5 oil temp was pegged at 230F

My 2020 X4M 750hp only saw 190-200F max oil temp with Amsoil

Not sure. My oil temp sensor on the dash stays right in the middle. Only put on about 1000 miles since I changed the oil a few months ago.

You can post a picture here of the dashboard i'll tell you around where it is.
2021 X5M has the same motor as my 2018 F90 M5 I had

I had bad experience with Pennzoil Euro 5w40 in my 2018 F90 M5, it also ran very hot back in 2019 maybe it was a bad batch or who knows.

If it was me, I would prob run Amsoil Euro 5w40 FS (i ran this for 4yrs straight in my 2020 X4M with 750hp)
Looks HPL Euro 5w40 is a good option as well.

There would have to be some quite massive failure or problem with the oil to overwhelm the temperature control like that. I’m guessing some other failure or anomaly was at fault. I can’t conceive of any oil brand having that sort of problem, you had something else going on.

I believe the previous owner or the cheaper 0w30 bmw oil didn't help either.

230? Why is that concern?
Also, those are two different engines, hence, two different set ups.

BMW's are known not to be so reliable with high oil temps long term or when being pushed so there's a fearmongering on the oil temps maybe not related to temp itself but maybe due to how the oils that most have used tend to lose their strength at high temps.

Man, I track my BMW and had oil temperatures reaching 300f. What in the world are you talking about? I still take kids to daycare, go ski etc. in the same car.
230f is temperature you will see in any vehicle.
I mean, how about this for regular mountain excursion with family:

What bmw you had running 300F? the 2011 328?
Maybe those run like that but the Fxx series generation like 335, 340, etc do not last with a 300F lol

Yes they do.
N55 in F30 335 is actually cut off at 340f, SAME as N55 in E90 335, as are S55, B58 and S58 in F and G series. The cooling system in F series BMW's is far more efficient and effective than in E series, but oil regularly shoots over 260 to 280f. I drove them on track.
The problem was with N/S63 engines. You are confusing N5X series engines (N51,52,53,54,55), which were extremely stout (short of N54 CBU issues and some N55 having sensitive rod bearings) and junk, which were first reiterations of N/S63. Those were not oil temperature-related issues, but hot V and poor material chosen to make valve stems, return lines, etc.
BMW circumvented that with extremely low oil temperatures (around 190f) in some later models prior to F90.
F90 and later have improved N/S63 engines.

You do NOT want oil temperature below 212f in regular driving. There needs to be higher temperature to get rid of contaminants in timely manner and allow additives to work properly. 220-230f oil temperature in regular driving is what you actually want.

Absolutely. Unless someone filled Pennzoil bottles with some good ole Lucas oil treatment
