Tip #1. Checking your tire pressure will lead to savings
Under inflated tires are arguably one of the most common reasons for not getting the best gas mileage. Go out and buy a reliable tire gauge. You should check your tires when they are cold as driving the car warms up the tires and the air inside them, thereby increasing the pressure. Keeping your tires properly inflated is an effective way to save gasoline. Use the inflation pressures as reflected in the owner's manual. Keeping your tires inflated will improve your cars fuel efficiency, save gasoline, and is a simple way to save.
