Yes, but none in California. Plus, the gas in CA leaves the refineries
already containing alcohol, so the ideas about using gas meant for
farm
equipment, etc., are non starters.

Grumble.

That sucks.

So move!

Why should I move? I can get alcohol free mogas. I taxi up and they fill
my tanks. Price is only a couple of cents higher than the local filling
stations.

Actually, it's about 10% less than that of gasoline IIRC. For automotive
uses, the compression ratio of the engine can be increased to get some of that back,
since the alcohol has a higher octane rating.

: to stay, at least in California.

From what I've read, it's more than just seals in the fuel system. The
alcohol can attack aluminum fuel tanks, IIRC.

Anybody had mogas issues with fiberglass wing tanks?

I've got fiberglass tip tanks.

No problems.

I looked into it briefly again today and feel the need to correct myself.
Apparently, the specific energy density of pure ethanol is about 60-70% that of
gasoline. Raising the CR to compensate yields the 10% less range I've heard quoted.

What state, and what airport?

I take it you're not in Kalifornia.

In which case, a move would be unnecessary.
