* Consult your owner's manual: This is the best resource for the precise location and oil change instructions specific to your car's engine.
* Look for a cylindrical canister: The oil filter is usually a fairly large, cylindrical canister. Look closely around the engine block on the passenger side.
* Use online resources: Search for "1987 Pontiac Grand Am oil filter location" along with your specific engine size on YouTube or a car repair website. Many videos show the location clearly.
Remember to always use caution when working under the hood of a car. Make sure the engine is cool and the vehicle is parked on a level surface.
