I'd like to again say thanks to everyone for their info on Ethanol enhanced fuel. I will be mixing my own as soon as I can - to see for myself, and the nearest station that sells E85 is still 40 miles from here.

I posted earlier about the horrible effects 10% ethanol had on my 86 EFI Toyota 4x4. I forgot to mention that this engine already had a number of mods to get some HP out of an archaic 2.4L 4 cylinder.
A huge number, actually including a custom cylinder head (not a Toyota casting), camshaft, header, injectors, a decked block and milled head to increase compression, custom pistons, flywheel, K&N filter element, 2.5" exhaust system, etc. And while all this means I have enough power to move the truck well, it gets horrible mpg and won't run on anything that isn't good ole' full oil unleaded. Maybe I'll try testing it again someday soon - I kinda broke the rear axle awhile back LOL.

So readers - please don't think that your stock 22RE equipped 4 cylinder Toyota truck won't run on ethanol blends - they probably will. I think we owe it to ourselves to try this, even by guess-timating a mix level at the pump. Maybe sometime soon we'll be able to push an E30 or E40 button on the pump and help our economy and our air quality. I'd buy it today if it was 5 bucks a gallon .
