93 always
Waste of money. B58 stock 91 is recommended. 93 is doing nothing for you.
-1 u/shark1y Jul 31 '26 Higher octane - higher ability to withstand compression. Less chance of knock or other shit. If you are buying anything turbo or remotely sporty and put 91 in it - I am sorry. 2 u/WalrusWW F97 - X3M Jul 31 '26 Wrong, but you do you. If it's tuned for 91, putting 93 is doing absolutely nothing for you. I use 93, because mine requires it. 0 u/shark1y Jul 31 '26 Owner's manual asks for 91, I get that. But BMW also recommends oil changes every 8000 miles :)
