About a week ago I lost my only close access to "pure" 92 fuel.....I then added about 10 gallons of an ETOH 91 to fill it up. A few days later I found a 93 BP station which I'm pretty sure also has ETOH in it & filled to the brim & reset the trip meter. MPG looked great based upon the trip meter & where the fuel gauge was indicating....sure enough after 206 miles it was still way above the half way mark....I filled it up to the brim....& WOW....7.3 gallons was all I could stuff in the tank = 28.2 MPG !!!! Was not babying it either.

I've driven this '07 stick about 58,000 miles since new in Dec. of '07......usually runs 24-25 mpg....never calculated anything close to 28.2 mpg before. Is it possible this first tank of 93 with ETOH could get that much better than the 92 pure I was using for the last 2 years???? I always assumed the pure should get 3%-4% better than a 10% ETOH blend?????
