Fuel for non-S 2007 Cooper
 

Purchased the Cooper yesterday. Saw that the Manuel recommends fuel 87 octane or above. Has anyone noticed problems using regular unleaded in the non-S model?

run away from the car
 

Hi, sell the thing. Truly run from it. I have put so much money into my 07. Google around. We are not alone.

I wouldn't put any lesser of an octane in the car than what is recommended from factory. The higher the octane the better it is for the vehicle. Here is a thread about 87 vs. 91. Might help give you some insight.

I run 91 octane

I run 91 too. If I were you though I'd sell it cause I put over 10k in my 06 cooper haha
