Step 2: Keep it in tune

Keep your engine tuned properly. Nowadays, most cars on the road have electronic ignitions that are simpler to maintain than they used to be, but there are still a few items that need attention.

  • The air filter should be replaced when you can't easily see light through it.
  • The timing should be properly adjusted.
  • The spark plugs should be clean, gapped correctly and firing properly.
  • Older cars and trucks may need the points replaced as well.

Keep your exhaust system in good shape. A hole in your muffler or along your exhaust pipe will reduce your gas mileage as well as making noise and a bad smell.
