I see an awful lot of "fear and loathing" about the "new" alcohol-blended gasoline on various internet forums.
I've been using 10% ethanol-blended gasoline (now called "E-10", but sold for years around here as "Gasohol") as my fuel of choice since about 1981 or so. For a very short time (I'm thinking about six months) the fuel was blended with (5%, I think) methanol; the ethanol blend replaced methanol.
I have had Z-E-R-O problems that I could attribute to the ethanol/methanol. I've used this fuel in everything from lawn mowers, Rochester Q-Jets, Holley Tri-Powers and 4-barrels, Mikuni carbs, Kehin carbs, TBI, Port FI,--you name it.
Install fresh rubber hoses; a "blue" accelerator pump cup and maybe a touch of additional richness (jetting) and you're pretty much good-to-go. I did have some problems with Holley needle 'n' seat assemblies--the O-ring around the outside went bad a couple of times. Replacing those O-rings with Viton 'rings instead of the cheap Chinese bulk "parts store" O-rings absolutely solved that problem--which may not have been alcohol-related in the first place.
There were a lot of problems in the early years, the alcohol content would "clean out" all the crap and water in the underground tanks at the service station. Of course, it cleaned out the underground tank by transferring that crap to the VEHICLE gas tank, the vehicle then (repeatedly) plugged the fuel filter and ran terrible because of all the water in the gasoline. The EPA has required that those old, rusty, leaky underground tanks be replaced--that is now a very rare problem. (I've seen ONE case in the last ~ten years--and that happened to a relative of mine in Colorado.)
Ethanol isn't the AntiChrist like some folks make it out to be.
It's terrible Farm, Food, and Energy POLICY, (I hate Corporate Subsidies) but it's fine fuel.
