Gasoline "Snow"?

Really?

I guess this throws out my concerns about finding alcohol in my mogas!

Jay, if you have any sense, you're looking for (and trying to avoid) *ethanol*
in your gas, not isoproply.

Given that the chunk of ice was white instead of 100LL blue (or you use
red gasoline, don't you?) I suspect that it is water that merely smells
like
gasoline.


Well, minimum octane for a '74 Cherokee 235 was 80/87, but I'll bet he uses
far more blue gas than red.

Mogas is my fuel of choice. It does leave kind of a red stain -- not as red
as 80 octane used to, but still reddish.

Aren't they *both* unapproved for use in aircraft engines?

By "small amount" of isopropyl alcohol (in a yellow container if you
use the illegal automotive stuff) I mean only a couple tablespoons to a
tank full. Not a 10 percent slug of ethanol like the gasohol crud.

Check your STC. IIRC, the one I had for my C-150 forbad ethanol.

You have to do some digging, but you can find an instruction from TCM
specifying the usage of alcohol to prevent the formation of ice
crystals in aviation gasoline. Have never found a similiar statement
from Lycoming.

However, Lo-Flo Prist is approved for both. If I'm not mistaken it is
not alcohol based, but is also intended for use in aviation fuels to
prevent the formation of ice crystals.

Looks like Prist is "diethylene glycol monomethyl ether".

Different type of alcohol. The stuff in gasoline is usually ethanol.
Isopropyl alcohol (IPA) is better at pulling water into solution in a gas
tank.

Car antifreeze?
