Everyone is looking for ways to save gas these days. You could invest in a hybrid or hydrogen fuel car, but if you don’t have the money for that here are some other suggestions. Turn your car off rather than let it idle. Idling uses more gas, contrary to previous belief. Fill up your tank in the morning or evening when the air is cooler. Use your cruise control to maintain a steady pace. Avoid heavy traffic and traffic lights. If you have a bicycle rack or ski rack on top of your car, remove it. These racks increase the wind resistance and in turn cause you to use more gas. Make sure you’re using the correct grade of motor oil, and change your oil filter frequently.
