Ethanol gas is terrible, I went down to Texas for a couple months and that's all they sold. Had a 2011 Accord and you could tell the engine was not happy at all.

I thought ethanol increased octane? My insight loves 6 gallons of regular bp and 4 gallons of e85.

While the ethanol increases the octane RATING it lowers the BTU's of the gasoline, so you have to burn more to get same amount of work done.

In my old testing:
E10 = 48 mpg
E0 (boat gas) = 53 mpg

Not to get too far off topic of the thread, but as Mista Bone said. Straight ethanol has about 66% the energy content per volume of straight gasoline, so to get the same energy you need to buy 50% more ethanol than gasoline. (A direct effect of this is the fuel injectors and fuel pump on an E85 engine need to have higher output to produce the same power.)

Consequently, an engine needs to be much more efficient running on ethanol than an equivalent engine running on gasoline to get the same price per mile, unless the ethanol is much cheaper... which (for corn ethanol) only comes about through subsidies that we pay for with our taxes.

ethanol burns slower than gas. .. thats how it cleans and warms your engine.. remember when it was "winter gas". now its "clean burning" because it heats the cat hotter to burn the carbon.. that means the ethanol is burning in the pipes and cat area and your not getting the energy out of it for your propulsion

The gen 2 insight has the dual ignition system and 10.8 to 1 compression. It seems to like the mix of e85 better than 93 octane in regards to performance, throttle response and timing used.

If enough ethanol is used, then the corn market will do its thing and be self support cs having to be supplemented by the government.

If that happens then world wide food prices will continue to increase.

Make more fuel but starve the world with higher food costs.
