Tune-ups

In the past, cars maintenance was required every 15,000 miles or so, checking and adjusting the points and ignition timing needed to be done often, and spark plugs and fuel filters never lasted much more than 15,000 miles (thanks to leaded gas). Today, point ignitions and leaded gas are a thing of the past. Tune-ups on today's new cars are only necessary every 50,000 miles or so and involve replacing the spark plugs, wire set, possibly the fuel filter, the air filter, and hooking the car up to an engine diagnostic system to diagnose problems before they become critical.
