I think there is a little more math to it than that.....


Edit: I would use...http://www.rims-n-tires.com/rt_specs.jsp take the % figure and times it by your miles. The % is found in the speedometer box after the inputs are selected. If this holds true I just banked 18.138 mpg.

Re-edit: Or here http://www.miata.net/garage/tirecalcold.html.....I got 10.7% on the first site and 18.9% difference on the second site due to my larger tires. Which new quote equals 19.52mpg.

But remember I am in the middle of the acetone trials. I just filled up today with 4oz of the juice.
