Main Menu Table Of Contents Adding Engine Oil ENGINE OIL FILL CAP Recommended Engine Oil Oil is a major contributor to your engine's performance and longevity. Always use a premium-grade 5W-20 detergent oil displaying the API Certification Seal. This seal indicates the oil is energy conserving, and that it meets the American Petroleum Institute's latest requirements. Honda Motor Oil is the preferred 5W-20 lubricant for your vehicle. It is highly recommended that you use Honda Motor Oil in your vehicle for optimum engine protection. Make sure the API Certification Seal says ''For Gasoline Engines.'' The oil viscosity or weight is provided on the container's label. 5W-20 oil is formulated for yearround protection of your vehicle to improve cold weather starting and fuel economy. Unscrew and remove the engine oil fill cap on the valve cover. Pour in the oil slowly and carefully so you do not spill any. Clean up any spills immediately. Spilled oil could damage components in the engine compartment. Reinstall the engine oil fill cap, and tighten it securely. Wait a few minutes, and recheck the oil level on the engine oil dipstick. Do not fill above the upper mark; you could damage the engine. API CERTIFICATION SEAL Ambient Temperature 326 2009 Ridgeline
