Mileage Calculation #8 - Shell gasoline (Premium)

(3143 - 3092 )/0.733 gallons = 70mpg

Hmmm, is Premium giving me less gas mileage? Not sure. the 3mpg difference from last time falls within my margin of error so I have no clue if there's really a difference. Hard to tell with less than a gallon of fuel.







I swear the Premium gasoline really is giving me a bit better pull of the line, but I can't say for sure. It could be in my head but I'm almost 70% sure that there's a difference. The cost difference is about $0.07-0.15 so it's pretty much negligible. I'm just concerned with performance and how good or bad it may be for the scooter that specifies Regular Unleaded, meaning 87 octane fuel is just fine.
