Engine Oil Make sure the API Certification Seal says ''For Gasoline Engines.'' API CERTIFICATION SEAL The oil's viscosity or weight is provided on the container's label. Select the oil for your vehicle according to this chart. 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 as shown on the chart. When using synthetic oil, you must follow the oil and filter change intervals given in the maintenance schedule. Ambient Temperature 5W-20 oil is formulated for yearround protection of your Honda, to improve cold weather starting, and to help your engine use less fuel. If 5W-20 oil is not available, a 5W-30 oil may be used. However, it should be replaced with 5W-20 at the next oil change. Maintenance 251
