Save gas by changing your air filterChanging your air filter will improve fuel economy and save gas. A clean air filter allows more air to flow into the engine, improving performance and saving money on fuel. You can also improve gas mileage by changing your oil to Amsoil synthetic oil, which allows you to have easier cold weather starts and better lubrication protection during the hot summer. Amsoil pours down to about -60 degrees below zero, and reduces drag in your engine. You can run your car for a full year with Amsoil, only having to change the oil filter at 6 months or 1/2 the allowed mileage.
