To start, I posted this in the main oil section here: https://www.bobistheoilguy.com/foru...
However, since this is a BMW engine I thought I may get more specific recommendations for what oil to use here. The available for oil for both the Supra and z4 seems scarcely available at mainstream retailers. My main driving habits are pretty hard on the street, especially here in florida so 0w-20 seems a bit thin but also concerned about warranty issues. My initial thought was LM 6600 but still seems a little too thin for my liking. 0w-40 was my thought but again, warranty. Any other thoughts?
