What Specific Engine Oil Are You Using And Why?

[Kashbringer]

Where did you find this oil???

I ordered it here. Never heard of the website before but it arrived on time.

5w30 on my 2021 has been awesome. 0 oil consumption, including a (rather fast…) trip from PDX to SFO and back and multiple autocross events between oil changes.

Ughhh I’m conflicted on this. On one hand i want to use the 0w-20 because it is the manufacturer recommended and don’t want any trouble, they know better than me, and i can see newer cars having tighter tolerances. but on the other hand it seems too thin although I’ve only owned older cars…i worry they recommend thin oil for better gas mileage and by the time the watery oil catches up with wearing the engine out it won’t be Toyota’s problem anymore since it will be out of warranty.

anyone have thoughts on this / anyone used 0w-20 into the 100k + range? I wonder if going to 5w-30 will have any adverse effects

My manual is aaaaalllllllllllll the way out in the car, and I can't be bothered to open another tab in Chrome, but I'm fairly confident 5w30 is identified in the manual as an acceptable weight oil to run in the B58.

The USA is the only country with 0w-20 as the spec for the B58TU. Most countries specify 5w-30.

I'm going to change over to some Motul Sport 5w40 soon.

I have a 22 with no consumption issues. I did my second oil change with the Supra oil, but I think for the next one I’ll switch over to 5w-30 because of the non US spec recommendation that zrk mentioned. Although as a daily I can’t imagine I’m pushing it that hard

0w20 is used to eek out every last drop of potential MPG. I can literally feel and hear the difference revving the car out on that oily water versus 5w30. The engine is much smoother and happier. Your mileage may vary, however. Ha.

Did my usual "break in " oil change after the road trip back from Bend Oregon @850 miles
OEM BMW filter + 5w30 LiqiMoly Ceratec
The car is a semi daily and likely will see the track maybe once a year.
We'll see what the UOA Blackstone report comes back as after this oil change in about 6 months

How was the Blackstone report?

How was the Blackstone report?

it was normal for the most part , it was not a lot of miles
Lead, copper all within normal spec
Water and contaminants minimal
I have since switched to Castrol Edge European formula 5W30
LMoly is not LL01 certified anymore
It is BMW LL01 certified and has good KV and HTHS characteristics
For a mostly street car it's the best oil IMHO

I'm looking to do my first oil change after my breaking in period on my A91 and have been debating if I should stick with the recommended 0w-20 or go with a 5w-30. My car is a weekend driver and Street car. I will never visit the track and maybe later this year I will tune it. What do you think about switching to 5w-30 so soon?

The factory oil weight is for fuel economy and is fine for a street car
The bmw engineers says it's ok , then I'd trust them
In my experience with bmw turbo engines, this being my 4th one, the factory 1yr/10k miles OCI is a bit long
I'd recommend 6mos/5k OCI and do an annual UOA just to see how your particular engine is doing
For a street car switching to 5W30 is perfectly fine, especially with a good C3 based oil with good HTHS , as it'll protect the engine better in the upper rev ranges
I just want some extra piece of mind that if I wanted to hoon around a back road that my oil gets a bit hot, it'll be better if it was a 30W vs a 20W, as oils do thin out over time

What are your thoughts on brands like Castrol Edge or Mobil 1 European spec?

What are your thoughts on brands like Castrol Edge or Mobil 1 European spec?

I'm currently using Castrol edge euro formula 5W30 and it's been great
Used the same oil in a 5w40 weight on the previous S55 F80 and the UOA came back squeaky clean
Haven't had any experience with mobil 1
If you want an alt the penzoil platinum european is also a very good street oil in the 5W30W
