The right fuels to use. Don't be foolish
Everybody really needs to check your gas mileage on the cheaper gases like Walmart, Sheetz, Giant foods, etc. I think that if you do this you will see that the 2 or 3 cent savings in cost is not worth...

But the fact is, gasoline with 10% ethanol in it (E10) can hold 0.05% water at 60 degrees (1 gal of water for every 2,000 gals of gas (E10)). After that it goes into Phase Separation and the gasoline now has 0% ethanol in it and 0% water in it.
Ethanol is capable holding more than 20 times the water that straight gasoline can.
Even more problematic is an effect called 'phase separation', this when the water in suspension in a gas / ethanol blend reaches the saturation point of the gasoline part of the mixture. At that point the ethanol, which aggressively absorbs and holds onto water, starts to drop out of the gasoline.
When this happens you end up with a tank of mostly gasoline with a layer of very water-laden ethanol at the bottom.
