Thanx.Makes sense.

 

WhenI got my mini the dealer had filled it with regular gas and not premium. I noticed it was jerking when you rolled up to a stop sign or when you were in reverse. I read these forums and filled the tank with premium. Wow what a noticeable difference. More power and no more jerky stops. The car runs much better.

 

If you look on the fuel door, it says "Premium Fuel Only"
