Scheduled Maintenance
(Gasoline Engine)
When the CHANGE ENGINE OIL message comes on, it means that service is required for your vheicle. Have your vehicle serviced as soon as possible within the next 600 miles. Your engine oil and filter must be changed at least once a year and at this time the oil life system must be reset.
When the CHANGE ENGINE OIL message appears, certain services, checks and inspections are required. When you bring your GM vehicle to Goodwrench for regular maintenance, we will likely perform one of two service packages – conveniently called Maintenance I and Maintenance II. We perform only the services that you need, depending on your current mileage and what services we did on your previous visit.
The first service should be Maintenance I; the second should be Maintenance II. Alternate between the two schedules
thereafter. Depending upon your driving habits, Maintenance II may be required more often.
