Why go half way? So go full synthetic oil but only half way on the octane? Why not go all the way and use 93? But you can use 89, then you can also use semi synthetic. Let’s open this can o worms…. Oh… to hell with it, I’m tired! 🥱89 octane. 93 is a scam if there ever was one IMO. Definitely full synthetic. Why go half way with the most important maintenance item. My son needed a valve cover replacement on his 3 series at about 250K miles. The cams/shaft looked new. Full synthetic always!
