How to Save Money on Gas: Check your Tire Pressure
One easy way to save money on gas is to keep your tire pressure at the appropriate level. You can find this out by looking at your car manual.
You can lose 1% on your gas mileage for every two PSI that all of your tires are below the recommended level. Most cars have tires that are about 5-10 times below!
Ask at your local gas station if they have a tire guage you can borrow (or buy one for about $5) and then if needed, head to the air pump.
