Gasoline "Snow"?

Remember that your fuel that morning was probably colder than it had

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.

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

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".

Car antifreeze?

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.
