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 cap.
* Look for a sticker under the hood: Many vehicles have a sticker detailing recommended fluids.
* Use the VIN number: You can use your vehicle's VIN number to look up the specifications on a Ford parts website or a trusted online automotive resource.
Using the wrong oil can damage your engine. Always refer to your owner's manual or a reliable source for the correct oil type and specifications before changing your oil.
