PS

I never had an issue with gasoline at -40F when I was in Grand Forks, North Dakota. Can't say the same for the diesel folks or airplanes but that was not because it was freezing. It was because the temprature was below the flashpoint, like E85 hence the E70 blends during winter.

Thanks for the tip and links. I don't have much money to throw around right now but when I do i may look into that. Maybe i can even get it through the university

huh??

water is denser than gasoline, therefore, gasoline floats on water.

methyl hydrate is gasline antifreeze. it acts to lower the freezing point of the water within the line/tank.

The problem with diesels is not that the fuel "freezes" per se, but certain components within the fuel turn to wax at what is called the "cloud point". Refineries adjust the cloud point with the ambient temperature, so a summer blend of diesel may cloud up in winter, preventing starting.

Glad someone said it, gas is a petrol, you dont see water floating on oil do you?

In diesel fuel the parafin waxes harden(The real "power" maker), and gel the system, espicially the fuel filter. In the cold climates they take out "some" of the parafin waxes and raise the cetane level for easy starting and running, but reduced power and fuel milage.

The Oilsands, Ft. Mcmurray, Alberta. The only place in the world where heavy equipment gets better fuel enconomy in the winter...riddle me that:icon_surp
