To be absolutely certain:
* Consult your owner's manual: If you have the owner's manual, it will show you exactly where the oil filler cap is located.
* Look for the oil can symbol: The oil can symbol is the universal indicator for the oil filler location.
* Pop the hood and carefully examine the engine: Look for a black, round cap with the oil can symbol.
* Check near the valve covers: The oil filler neck is often near the valve covers on top of the engine.
Be careful when checking or adding oil. The engine will be hot after running. Allow it to cool down before attempting this.
