Right now, where I live in Alabama, gas is nearly or right at $3.00 or more a gallon. I heard on the radio that by the time it's Spring Break, gas is expected to be about $3.50-$3.75 a gallon and in some places $4 a gallon. Any tips that can help people save money on gas or that can help them get more use from their gas, I'm sure will be welcomed knowledge! :)
I found out through both an article I read many years ago and also a show that I watched that if you purchase your gasoline at night time and in cooler weather, you will actually get more fuel for your money. Heat and sunlight causes evaporation. While you are pumping your gas in the daytime, the sunlight is actually already working to evaporate your gasoline before it ever hits your tank. It may say that you just bought 10 gallons of gas, but in reality, evaporation may have made you lose a gallon!
Also, do not use the gas pumps at a gas station when they have fuel tank trucks present and pumping fuel into their systems. If you use the gas pumps while they are being filled, you are going to get air in your tank and lose out on the fuel that you think you are buying. Plus, air in your tank is not good on your car.
