Q: How often do Lancers have to be serviced? A: For the earlier Lancers, that's the 1800's and Evos 1-3, the service interval is 6,000 miles (or 6 months) with a recommended intermediate oil change every 3,000 miles. The major cam belt service comes around at 40,000 miles. The Evo 4 onwards should be serviced every 4,500 miles (or 6 months) with more major service intervals every 9,000, 18,000 and 45,000 miles (cam belt). Each 4,500 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 18,000 miles 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.
