Adding Engine Oil Recommended Engine Oil Oil is major contributor to your engine's performance and longevity. Always use a premium-grade 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. It is highly recommended that you use Honda motor oil in your vehicle for as long as you own it. 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. Do not fill above the upper mark; you could damage the engine. Make sure the API Certification Seal says ''For Gasoline Engines.'' API CERTIFICATION SEAL Maintenance CONTINUED 143
