How to Change the Oil in a Mercury Cougar

If the owner of a Mercury Cougar is mechanically inclined, changing the oil at home can save some money. It is not difficult to change the oil; however, the owner will need a pair of jack stands in order to safely do the job. Parking the car in a garage is the best way to change the oil, or in a driveway if the owner does not have access to a garage.

1. Buy a pair of jack stands from an auto supply store so you can change the oil in your Mercury Cougar. You also need an oil drip pan and a bottle of replacement oil. Ask a store clerk to help you choose the right oil, or check your car owner’s manual to find the information.


2. Park the Cougar in your garage or driveway. Do not attempt to change the oil if you have to park in the street; use a friend’s garage or driveway instead. Place some pieces of cardboard under the vehicle in case any excess oil leaks from under the Cougar during the oil change.


3. Retrieve the car jack from the trunk and lift the front end of the Cougar. Slide the jack stands under the front end and then pop open the hood. Unscrew the oil cap and take out the dipstick.


4. Slide under the Cougar with the oil drip pan and wrench. Put the oil drip pan under the drainage plug and remove the plug with the wrench. The old oil will then start to drain into the pan. Once the oil stops draining, tighten the drainage plug and climb from under the vehicle.


5. Pour in the new oil and use the dipstick to determine the proper amount to add. Put the dipstick in and screw the oil cap back on. Shut the hood and lift the front end of the Cougar with the jack to slide out the jack stands. Lower the car all the way down to finish the job. Empty the oil in the drip pan into a disposable container, to take to a gas station or recycling center.
