In order to extract the full measure of performance and economy from your engine it is essential that it is properly tuned at regular intervals. A regular tune-up will keep your Datsun's engine running smoothly and will prevent the annoying breakdowns and poor performance often associated with an unmaintained engine.

All 1973-77 models use the conventional breaker point ignition system except for 1975-77 California cars and 1977 810's which use an electronic system. All models made in 1978 and later (except diesels) utilize this system also.

On 1979 and earlier cars, a complete tune-up should be performed at least every 15,000 miles (24,000 km) or twelve months, whichever comes first.

On 1980 and later models the interval is 30,000 miles (48,000 km).

This interval should be halved if the car is operated under severe conditions such as trailer towing, prolonged idling, start-and-stop driving, or if starting or running problems are noticed. It is assumed that the routine maintenance described in has been kept up, as this will have a decided effect on the results of a tune-up. All of the applicable steps of a tune-up should be followed in order, as the result is a cumulative one.

If the specifications on the underhood tune-up sticker in the engine compartment of your car disagree with the Tune-Up Specifications chart in this section, the figures on the sticker must be used. The sticker often reflects changes made during the production run.

Other than the periodic changing of oil, air and fuel filters as outlined in , diesel engines do not require a tune-up, as there is no ignition system.
