I know there is a lot of talk regarding what oil to use in BMWs if you aren't using their brand synthetic oil? I have searched through many online forums. My car just went out of warranty since it I just drove it over the 50,000 miles (currently at 54000) I live in South Florida so it does get in the 90s in the summer. I am planning on changing my oil every 7500 miles.
I know the below oils are approved with BMW Long-Life rating, but does it matter which one I pick? OR should I just buy whichever one below I can get the best deal on?
BMW Long-life rating LL-01 Approved Synthetic Oils for the US Market:
* Castrol Syntec European Formula SAE 0W-30
* Mobil 1 SAE 0W-40
* Pennzoil Platinum European Formula Ultra SAE 5W-30
* Valvoline SynPower SAE 5W-30
Any help would be much appreciated. Thank you!
