* Open the hood: Locate the hood release lever (usually inside the car, near the steering wheel or under the dash). Open the hood and prop it up securely.
* Look for the biggest cap: The engine is a fairly large component with multiple caps. The oil filler cap is usually one of the largest, often yellow or black plastic and easily visible.
* Check for the oil can symbol: The cap will usually have an oil can symbol imprinted on it, making it easy to identify.
