The sky ain't fall'n just yet.
Actually GM did a lot of analysis on "corn-fuel" and found that most cars and trucks can run up to about 40% ethanol in NON-flex fuel machines before performance started dropping off. Ford studies show the same thing.
I run 10% in everything I own, (because it's the law in Michigan to sell anything with any less) and have yet to have any issues. I also run it in my 1973 sleds and it works fine. Weed wackers, generators, lawn mowers, a 1949 ford 8N tractor...everything. NO issues.
While there might be some washing machine motors out there that have non-solvent based gaskets and o-rings, not too many machines will fail because of the corn fuel.
Octane goes up with the use of it, but the performance drops off...which equates to gas mileage losses for most.
There is a huge resistance against corn fuel use by the petroleum companies and lots of disinformation being pumped around about this stuff. So be sure you take what you hear about this....from taking away food from babies mouths, to engine failure, to costing more to produce than it is sold for....btw...most farmers in the grain belts belong to cooperatives that use this stuff nearly exclusively and those big John Deer pieces run on it just fine.
One more thing...everytime you drop some fuel line cleaner or octane booster in your tank...guess what the main ingredient of that stuff is?
Standard Oil Company put de-icer in their gas way back in the 1950's and it didn't kill very many motors, did it?
