* Your owner's manual: This is the definitive source. It will specify the recommended oil type (weight and specification, such as 5W-30 or 10W-30, and API certifications like SN or SM).
* The sticker on your oil filler cap: Sometimes, the recommended oil type is printed on a sticker under the hood.
* The engine itself: The engine code (often found on a plate on the engine block) will help identify the engine type and allow you to search online for the recommended oil.
Without knowing your engine size (e.g., 2.3L, 2.5L, 3.0L, 4.0L), it's impossible to give you a precise recommendation. Using the wrong oil can damage your engine.
