This process is fairly easy to do, and not many tools are needed.
-Open end wrench or ratchet
-Oil filter wrench
-NEW oil filter
First, place your car on a solid, level ground so that you are able to safely jack up the car. Place some cardboard underneath to car to catch oil spills.
*Warning* Oil burns are VERY dangerous. Allow two hours for your car and oil to cool down before you begin the oil change.
The first step is to drain the old oil from the oil pan. Unscrew the drain plug in the oil pan and let the old oil drain into the oil catch (make sure you have the oil catch placed directly underneath the oil pan, or you could have a huge mess on your hands). Also, you can recycle your used oil; most full service gas stations accept used oil.
Next, you need to remove the old oil filter. You will need an oil filter wrench for this. Turn the filter (using the wrench) counterclockwise until the filter breaks free (use caution, the filter is still filled with oil and can spill easily).
Now it’s time to install the new oil filter. Before installation, you must lubricate the rubber gasket on the end of the filter using some of the new oil you purchased. (To purchase new oil, simply go to an AutoZone or comparable establishment, tell them your make and model and they will show you exactly what kind of oil to get). Fill the new filter about two-thirds of the way to the top.
Installing the new filter is easy. Simply (and carefully) screw the new filter in a clockwise motion into place using one hand (no oil filter wrench required). Over-tightening or not tightening the filter enough will both cause leaks, so just screw it on as far as it will go using one hand.
Now that the new filter is installed, it is time to refill the engine oil. Unscrew the engine oil fill cap and insert your funnel. Put a little bit less than the fill amount of your car (for example, if your car holds 4 quarts of oil, put 3.5 quarts of oil into the engine.) It is safer to add less than the full amount of oil in case there is still oil in the engine that we cannot account for. Check your owner’s manual for the oil amount for your car.
Now, check your oil level using your dipstick and add more oil until you are at the desired amount.
Screw back on the oil cap, and you are finished! (Oil spray from oil caps incorrectly screwed on can cause engine fires).
