How often should I bring my car in for a tune-up? |
|
 |
Cars made since the early 1980s only need tune-ups every 30,000 miles. If your car was built before then, you may want to tune it up every 15,000 miles, and your tune-up will be more complicated than the tune-ups done on modern cars. If you own a brand new car, it may not need a tune-up for 100,000 miles. New-fangled "tune-ups" are named in honor of the old ritual, but don't resemble it very much because advances such as electronic ignitions systems, engines running on unleaded fuel, and computer-controlled systems have made the old adjustments less frequent or even obsolete. The new tune-ups usually cover new spark plugs, a new fuel filter, a new air filter, a new PCV valve, and--only if needed--a new rotor, a new distributor cap, ignition wires, and a carburetor adjustment. Some mechanics also test the computer system and do an engine analysis. Sometimes an oil change is included, but oil changes are part of a more regular maintenance schedule and should take place every 3,000 miles.
