I have a new 2024 BMW X4 M40i and want to do my own oil changes. I believe it is the B58 B58B30O1. The manual recommends oils that meet BMW spec Longlife 17-FE+ 0W-20 or whatever BMW qualified service provider recommends. I called the local parts department and asked if there alternative weights I could use and he said that LL-01FE 0W-30 and LL-01 5W-30 specs are both technically suitable. I called 2 other BMW parts departments to try and confirm and one wouldn't tell me if there were any other technically suitable options and the other said there were but he wouldn't use the 5w30 because it doesn't get cold enough. He didn't know what he was talking about because it's the first number, being 5, that is the winter rating, would make it more suitable for warmer climates.
Anyway, can anyone confirm alternative oil weightings I could use in my new car. I'd prefer to be able to print something from TIS.
