Adding Engine Oil, Changing the Oil and Filter Synthetic Oil You may use a synthetic motor oil if it meets the same requirements given for a conventional motor oil: it displays the API Certification Seal, and it is the proper weight. You must follow the oil and filter change intervals given on the maintenance schedule. Engine Oil Additives Your vehicle does not require any oil additives. Additives may adversely affect your engine's or transmission's performance and durability. Changing the Oil and Filter Always change the oil and filter according to the recommendations in the maintenance schedule. The oil and filter collect contaminants that can damage your engine if they are not removed regularly. Changing the oil and filter requires special tools and access from underneath the vehicle. The vehicle should be raised on a service stationtype hydraulic lift for this service. Unless you have the knowledge and proper equipment, you should have this maintenance done by a skilled mechanic. 1. Run the engine until it reaches normal operating temperature, then shut it off.
