Don't know where you're getting these Fit gas mileage estimates from. Spec is:
Manual: 28/34
Auto: 27/34
There is a lot of confusion about the octane requirements of the Smart. You may be looking at Euro-based RON octane with the 95 number. There are two methods of measuring octane - research and motor and they can be as much as 10 points difference. US pump octane is based on the average of RON and MON and is typically about five points lower. So 95 RON and 91 pump are about the same.
