Nothing other than Premium has touched my new Mini's big red lips, but I do find myself looking longingly at the Regular. Since I am leasing this wonderful car and don't want to break any rules, I will play it straight. But a friend did ask me why I was paying for Premium when Regular would do. She said, "Oh dealers always tell you to use Premium. It doesn't matter at all." Has anyone ever used Regular here and lived to tell about it?

 

It matters...use premium. The engines are designed for the stuff and get better fuel economy if you use premium. Your MINI will thank you.

 

It's been discussed a lot.
