Ethanol is in itself an anti-knoc compound. Straight methanol when used by
itself as a motor fuel will support a compression ratio of 15.0 to 1. But
it takes a whole bunch of it to yield the same number of BTU'S as gasoline.
The real down side of methanol blended fuel is the poor fuel mileage.
If you blend in 10% methanol to gasoline, you get 10% worse mileage.
The only benefit is to the taxing agencies. Cities, States, Feds. The
greater volume of fuel that is pumped into your tanks is a direct boon to
their coffers.
They are presently looking at "per mile traveled" fees in order to
snag all these electric vehicles that don't use gasoline. But, that "per
mile fee" is going to effect every vehicle, not just electrics and hybrids.
It's just another tax, hidden by calling it a "fee". They ought to be
calling it a "fleece".
