[QUOTE=Ecky;518643]I've read that adding ethanol negatively impacts this car more than most (though haven't experimented myself), probably because it's so carefully designed for pure gasoline. I would bet that trying to burn anything else would be suboptimal.

Why build an engine that would be better at burning something other than gasoline, when you're going to be putting gasoline in it? I could see some poorly designed engines benefiting from a small addition of hydrogen by accident...[/Q[QUOTE]

Jan 15, 2009 - Honda's 2010 Insight gasoline-electric hybrid isn't the substantial ... Regular (87- octane) gas specified.

The epa require 10%Ethanol in reg. And mid grade fuel hear in Montana premium is alowed 0%Ethanol.
In Oregon and Washington only Boat /marine, and 100 Octane is alowed 0% at a higher than premium price and Boat /marine is considered non-road use. This is what I used in my 72cc chain saw, because Ethanol absorbes watter ,and has a veary short shelf life sub 1 month (more like 2weeks) and can ruin a saw over the winter All grades are 10% aka E-90, or E-85 is of course 15% Ethanol.
By the Westcoast standards and your statement the Insight is poorly designed ... it is designed to use a fuel that is not available... at 90%of gas stations or the rong grade 87Vs 91 or 100 What is the programming set to do when the "rong octane"is used to get rid of the Ethanol my very limited knowledge the computer compensates for the out of tolerance fuel by remapping...too much =detune , too little = more detune in a different way..with the short shelf life of to days fuel the computer has to be able to compensate for " sour fuel"(1-3weeks old.)

Im not picken... just pointing out some read between the lines factoids...
