a stretch of cold for here weather coming up----mid teens to 20's----and it

Part of the regimen has always been to toss in a jug of fuel system water
remover/anti-freeze. HEET or whatever is on sale.
Recently the powers that be mandated that we run a gas/ethanol blend year
round. Makes the corn farmers happy I guess. If I'm running 10% ethanol,
the fuel system anti-freeze is redundant--correct? AFAIK all the stuff is
is ethanol? Or is there something here that I'm not seeing?

I don't know, but the gas-line anti-freeze stuff we get here is said
to be Methyl Hydrate. Is that Ethanol?

Most gas-line antifreeze is methyl alcohol (methanol).

Some is isopropyl alcohol.

I've never seen ethyl alcohol (ethanol) used, but it would work.

The poison warning usually tells which it is.
