The Nissan Path

Anyone know if Ethanol free gas is really better than the 10%-15% generally found in gas at pumps? Any Pros/Cons?

you get more miles per gallon on pure gasoline than you do with ethanol. for example the path can get maybe with feathering the gas 23-24 mpg highway with pure gas and 18 with ethanol mix.

I'd love to get 23-24 mpg.

From personal experience (my wife's Mariner is flex fuel), I've noticed we get 30.3 mpg highway with pure gasoline, 29.2 mpg with a 10% ethanol blend, and 27.2 with E85. 3 miles a gallon doesn't seem like much, but we are only dealing with a 4 cylinder (which I HATE getting into right after driving the Pathfinder... the lack of acceleration drives me nuts!). Basically, in order to be cost effective, I need E85 to be more than 10% less than the cost of regular gas...
