You do you. Just don't spread misinformation. No where in the manual does it state 0w-30 is the ONLY viscosity approved or is what they want. What BMW wants for this engine and their other current turbo engines is a LL01 oil.
In the manual it doesn't mention any specific viscosities at all. It only states BMW Long Life 01 FE or BMW Long Life 01 approved oils should be use. You keep bringing up the 50k mile warranty which makes me believe you're not going to keep it past the 50k for very long. Others might and would want to protect their engines for the long haul in the event they use it in "severe conditions". I along with many others as shown in this thread and other oil threads switch to a 40 weight oil especially if tracking the vehicle due to the higher protection that 40 weight will provide in those "severe conditions" aka higher engine temps. I live in So Cal, all the tracks here are in the desert. I'm going to protect my engine with a 40 weight oil. My last free oil change the dealer put in 5w-30, going to switch that out before my next track day. |
I think you're being inaccurate about misinformation. The sticker under the hood of my vehicle reads 0W-30. This is due to the car being sold in different markets and may support different fuel formulations. The LL01 is the required adequate standard for a long life, extended drain oil. That is the reason it does not say in the manual like it used to.
If you want to use heavier oil, that's your opinion. You're addressing a problem that doesn't exist and it's opinion-driven.
