The owner's manual will specify the recommended weight (e.g., 5W-30, 10W-30, 15W-40) and type (conventional, synthetic blend, or full synthetic) of motor oil. Using the incorrect oil can damage your engine.
If you don't have the owner's manual, you can:
* Check the oil fill cap: Sometimes the recommended oil type is printed on the oil fill cap.
* Look for a sticker under the hood: Many vehicles have stickers under the hood that specify maintenance information, including oil type.
* Use a vehicle identification number (VIN) lookup: Websites and repair shops can use your VIN to identify your vehicle's specifications, including the recommended oil type.
Don't guess – finding the correct oil information is crucial for the longevity of your engine.
