Removing Ethanol from Gas?

It's is like the guy who spent $25,000 on tools to build
furniture for his house, to save 25% on the furniture.
During WWII the Army published flight manuals for fighters
(and bombers) for different grades of fuel, 80/87, 91-96,
100/130 and 115/145 being refined. But some battlefields
did not have supplies of all grades. So you might have a 54
In Hg. MAP with 115/145 and only 40 inches with 100/130.

But what octane do you get from home refined mogas?

| There is also the issue of performance. As I understand
