Main Menu Table Of Contents Adding Engine Oil 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. ENGINE OIL FILL CAP 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 top of the valve cover. Pour in the oil slowly and carefully so you do not spill. Clean up any spills immediately. Spilled oil could damage components in the engine compartment. Install the engine oil fill cap, and tighten it securely. Wait a few minutes, and recheck the oil level (see page 240 ). Do not fill above the upper mark; you could damage the engine. Maintenance API CERTIFICATION SEAL Ambient Temperature 287 2008 TL
