My buddies '92 MX-6 takes premium, or it tells him to anyway. It's the 6cyl. and he knows nothing about cars, but I'm not gonna tell him to not use premium, I say if the owners manual reccommends it, use it. Whatev, I try to give him advice on his car all the time (don't take it to a shop to have the oil changed, most of them around here try to peddle the BS: "You don't need your oil filter changed this time." instead, buy the stuff and let me do it) but his dad is overbearing and won't let me do something as simple as change his oil, yet he asks me what I think the cause of noises/problems with his car are.
