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.
