Improve My Gas Mileage - Buy your gas in the morning or evening

Gasoline becomes denser in colder temperatures. Gas pumps are set to measure the volume of the fuel that you pump and not the density.

This means that if you fill up your gas tank in the cooler morning temperatures, or in the colder evening hours, that you’ll be getting better gas price economy. Try to fill up your gas tank later in the evening to avoid the rush of day hours.

This doesn’t quite fit to your daily schedule? How about turn your car into one of the Hydro Fuel Cars?
