Re: $20 a gallon gas proposed.....
Ethanol itself is not corrosive to metal. What it is is hygroscopic, meaning it will absorb and hold water in solution- rust on steel parts will result. Also, some rubbers and plastics will swell and get gummy or harden with alcohol use.
That being said, many Ford cars and trucks and almost all GM vehicles can run on up to 85% ethanol now- no problem. They could use 100% alcohol with additional programming. The right plastics, rubbers and alloys solve these issues.
Little Briggs engines have been converted for alcohol use for years with serious power improvements...serious consumption increases too, but you can't have everything.
