v API CERTIFICATION MARK API SERVICE LABEL Maintenance Main Menu Table of Contents Engine Oil You can determine an oil's SAE viscosity and Service Classification from the API Service label on the oil container. A fuel-efficient oil is recommended for your Honda. This is shown on the API Service label by the words "Energy Conserving". This oil is formulated to help your engine use less fuel. The API Service label also tells you the service classification of the oil. Always use an oil that is labeled "API Service SJ". This service rating may include other classifications, such as CD. These additional classifications are not a problem, as long as the label also carries the SJ classification. The oil container may also display the API Certification mark. Make sure it says "For Gasoline Engines." CONTINUED w
