How often does my Lancer need to be serviced?

For the earlier Lancers, that’s the 1800’s and Evos 1-3, the service interval is 10.000 kilometers (or 6 months) with a recommended intermediate oil change every 5.000 kilometers. The major cam belt service comes around at 60.000 kilometers. The Evo 4 onwards should be serviced every 7.000 kilometers (or 6 months) with more major service intervals every 15.000 kilometers, 27.500 and 70.000 kilometers (cam belt). Each 7.000 service should include the changing of the AYC fluid (GSR) as well as the normal oil and filter change however, the interval for changing the AYC fluids maybe extended to 30.000 kilometers at a later date.

Depending on the use of the car it maybe wise to service the car sooner than the manufacturers recommendations, for example if you do a lot of trackdays, then increasing the servicing accordingly with recommended oil changes (engine and drivetrain) after each event.
