(May 11, 2009) – Here’s a tip for buying gas – buy early in the morning. As the temperature rises, the gasoline in the pump (yeah, I know it’s actually in a tank in the ground) expands. The pump thinks it’s giving you more gas than you are actually getting, and the error increases as the temperature gets hotter.
Only folks in Hawaii don’t have to worry about this. State law requires their pumps to take temperature into consideration.
So, buy your gas early in the morning or late at night when the temperatures are lower and the pump more accurate. Get what you pay for.
