Adding Engine Oil ENGINE OIL FILL CAP 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. Recommended Engine Oil API CERTIFICATION SEAL 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. Oil is a major contributor to your engine's performance and longevity. Always use a premium-grade 0W-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. 614 2011 Odyssey
