Question for folks that live where you get real winter (The question on fuel injector cleaner made me think about this one): There was a time where I was sure that using gas line antifreeze/water remover was useful in the winter. Sold as small bottles that contain a few ounces of methyl or propyl alcohol. Now that most of the gas I buy has ethyl alcohol already in it does that eliminate the problem of water condensation and accumulation in the gas system?

Google phase separation to see what happens when ethanol in gasoline absorbs water.

Lived my first 40 years in in Northern PA and upstate NY I started in October and ran it in every tank full till March since it is a simple and cheap form of insurance.

I remember a cold February day riding to a construction job with my older brother, we passed 7 cars dead along the 118 in central PA. Turns out they had all gotten gas a the same station earlier that morning....

Diesels too, My buddy here in CA never heard of using it in his GMC diesel but when we hunted late season Colorado elk this past January he found out the hard way....

First rule - never let our tank go below half empty... That's when it will freeze - why I don't frigg'n know but the rules works.

I'm from Buffalo originally.. So I pretty much know.

they used to make gas line anti-freeze, that was basically alcohol you put in your tank every once and a while...

If you do use it, HEET in the yellow bottle is for 4 stroke gas engines only. For 2-stroke engines with mixed oil and diesels, only use the Iso-HEET in the red bottles. It's not the same stuff.

This really hasn't been all that much a problem since under ground gas station tanks have been replaced by plastic which doesn't leak like the old metal ones.
