Car engines tend to deteriorate over time with constant use, so many car owners need to have their vehicles maintained so they keep working efficiently. This maintenance is called a tune-up, but the term can be unclear.
A typical tune-up will replace items like air filters, distributor points, the distributor cap and the spark plugs. The mechanic working on the car will also make specific adjustments to elements such as ignition timing.
The term "tune-up" was common with cars made before onboard computers. These computers can automatically make the required adjustments to the engine. Thus, there is less need for mechanics to adjust the engine by hand.
Because the term fell out of common usage, at most shops a car owner won't get all he wants by asking for a general tune-up. The shop will ask what specific items need to be checked, and it's up to the car owner to know which parts need to be looked at or replaced. The vehicle manual will usually have replacement recommendations based on the miles the car has put on since the part was installed.
Regular maintenance of a car engine not only helps the car work efficiently, but should also prevent potential problems.
