You can easily take care of a few items without going to a service station. One of them is the air filter. A clogged air filter leaves your engine gasping for breath and means you’re probably running with a “rich” mixture, that is, more gas and less air. Many department and auto stores carry air filters, and they are simple to change. A clogged air filter can cost you 1 mpg. Replace your air filter regularly.
