The term "tune-up" usually denotes the routine servicing of the engine to meet the manufacturer's specifications. Tune-ups are needed periodically according to the manufacturer's recommendations to ensure the vehicle runs as expected. Modern automobile engines typically require a small number of tune-ups over the course of an approximate {{convert|250000|km|adj=on}} or a 10-year, lifespan. This can be attributed to improvements in the production process in which imperfections and errors reduced by computer automation, and significant improvement in the quality of consumables such as the availability of [[synthetic engine oil]].

Tune-ups may include the following:
* Adjustment of the carburetor [[idle speed]] and the [[air-fuel mixture]],
* Inspection and possible replacement of ignition system components like [[spark plugs]], [[contact breaker]] points, [[distributor]] cap and distributor [[rotor (distributor)|rotor]],
* Replacement of the [[air filter]] and other filters,
* Inspection of [[Vehicle emissions control|emission controls]],
* [[Poppet valve|Valvetrain]] adjustment.

The term  "[[Italian tuneup]]" denotes the driving of a performance car, such as a [[Ferrari]], by mechanics finishing the tune-up to burn out any built-up carbon.
