Main Menu Table Of Contents Adding Engine Oil 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 shown on the multiinformation display. Ambient Temperature API CERTIFICATION SEAL Make sure the API Certification Seal says ''For Gasoline Engines.'' An oil with a viscosity of 5W-30 is preferred for improved fuel economy and year-round protection in your vehicle. You may use a 10W-30 oil if the temperature in your area never goes below 0°F ( 20°C). Engine Oil Additives Your vehicle does not require any oil additives. Additives may adversely affect the engine or transmission performance and durability. 292 2008 TSX
