For those of us that are at the intersection of the Venn Diagram of Circle One being up where it freezes, and Circle Two, where ethanol gasoline is the standard, I have a question.
In many years past, we almost always carried a yellow plastic pint sized container of HEET or something brand similar. If you had or suspected gasline freeze, you dumped this in and hoped it would clear any crystals or blockage and the car would start and run again. Whether or not it worked, is anyone's guess. The other thing would be to take this relatively cheap bottle and put it in to a tank of gas to 'absorb' the water in your gas and burn it up, thus avoiding the dreaded gasline freeze up.
Now that most of our regular gas is 10% ethanol, does this provide the same or better function as putting in a bottle of HEET? Can a vehicle running on 10% ethanolated gas have gas line freeze?
Oh, did HEET ever work or was it all a figment of advertiser's imagination?
