How necessary is it to use premium grade gas in a MINI Cooper base model (not an ‘S’ or larger model)? What are the potential problems from using regular gas? Thanks.

Pretty sure all the Mini’s specify premium fuel. Look in your manual or it probably says premium only on or near the gas cap. Potential problem of not using premium would be detonation that could put a hole in a piston or otherwise destroy your engine. The difference in gas price certainly isn’t …

The difference as others here will no doubt tell you is whether premium gasoline is “recommended” or “required” by your Cooper’s manual. If premium gasoline is required, it means just what it says. An attempt to save money at the gas pump will cost you much more in the long run. On the other hand…

I just bought a 2007 Mini Cooper base model. The following is direct from the manual regarding fuel. What appears to be a requirement at first, really turns out to be a recommendation. Someday when the “honeymoon’s” over, I may experiment with regular to see if I notice a difference. The car’s p…

Just to amplfy, you will save $64 for every 10,000 miles you drive. I think the savings are insignificant. No one knows your Mini beter than BMW. If they require premium, then use it.
