Gas Line Antifreeze..

With all the super cold outside temperatures lately...
Have you been adding any Heet with a water remover to fuel, or similar product?

Nope. I haven't. FWIW though, here's a couple videos testing a few different products.

I usually do one a winter, but I find I don't need it as much since I use ethanol free gas

Got to -40F here, no fuel issues. Steering started getting hard and cold after an hour drive at 70 mph in those temps!

Interesting.. -40 & windchill burr...ya the steering rack sits low & is fairly exposed.
If I lived in that kind of winter climate, I'd be tempted to find a way to insulate the main body of the rack somehow. Polyurethane spray it?

Which is odd, because the Heet and Iso-Heet products are just alcohol blends... an alcohol chemically bonds to water and allows it to be ran through the fuel system and burned as would normal gasoline...

Ethanol is also an alcohol... so the 10% ethanol blends we have just about everywhere now... ought to do the same as adding in Heet to the E0 (0% ethanol) fuel.

Like I said.. odd.. and "ought to"... but meh.. you know how reality appears sometimes. Whatever works I suppose.

It seems to me that ethanol just evaporates and replaced itself with water. Engine doesn't run as well, poorer mpg. More noticable in small engines. (Lawn mowers and vw)

Strictly speaking, ethanol should not and typically does not evaporate in a mostly sealed container (like the gas tank/fuel system) much, and certainly not any differently than isopropyl alcohol does.

The regular "Heet" is methyl alcohol, the premium stuff in the red bottle, "Iso-Heet", is IPA, isopropyl alcohol.

IPA has an extra Carbon-Hydrogen pair bond. Little different structure.. All alcohols are similar and just hydrocarbon chains. But evaporation of alcohols is dependent on their molecular weight, and ethanol and IPA are not very far apart.

Your experience is quite perplexing, based on how chemicals are supposed to act (in our universe).

Personally, I hate having any alcohol added to my fuel, period.. in small engines, like you mentioned, it can really degrade performance. It reduces the amount of energy int he fuel too, fewer BTU's means less fuel mileage in the vehicle.

I hear you, and you can't argue facts, but my air cooled VW and lawnmower won't hardly run on the stuff

Don't doubt that one bit... small engines especially.. I bet you probably have to put lead additive into the fuel for the old vdub since leaded gas isn't a thing anymore too.

My dad used to have to do that with his Type 2 and Thing.

It actually ran fine on ethanol free, I crashed it last year and had to let it go
