How to open fuel cap on MINI Cooper?

Your gas door on Your MINI Cooper is locked when the car is locked. So make sure the car is unlocked first then push on the door and it will open allowing You to remove the cap underneath. Rotate the gas cap counterclockwise to remove. MINI Coopers can ger up to 28 city / 37 highway mpg. Driving at slower speeds, going easy on the gas and brake pedals, and properly using cruise control are all strategies for achieving better fuel efficiency. A well-maintained vehicle with properly inflated tires and good alignment can also stretch the gas tank further. It is strongly suggested to use 91 octane for all MINIs, but they do allow the use of 89 octane in the "S" and the JCW, and 87 octane in the MINI standard.
