Make Sure That Gas Cap is Tight
Gasoline can escape from your tank if the cap isn’t screwed on as tightly as possible. Double check the cap after you fill up.
Check Your Tire’s Alignment
Improperly aligned tires can drag down your fuel economy by putting unneeded work on your engine.
Quit Your Idling
Waiting for someone in your car? Turn it off in the meantime. Idling can use up more gas than you might think. A good rule of thumb is to turn off the engine when you’re not going to be driving for more than 30 seconds.
