One of the most common tasks to perform is replacing your engine oil. Frequent oil changes are perhaps the most important procedure you can do to maintain and prolong the life of your engine. With the better oils that are available today, the requirement for frequent changes is diminishing. Even though Porsche recommends oil change intervals that are much further apart than in the past, I usually recommend that you keep the changes under 5,000-miles. If you don't drive your car too often, you should change the oil at least once a year to keep things fresh.

Make sure to properly dispose of your used motor oil. Most oil change shops will accept your used motor oil at no charge.

The first thing you need to do is to make sure that you have everything that is required for the job. Nothing is more frustrating than emptying your oil, only to find out that you don't have a replacement filter or enough oil. You will need an oil filter and gasket, a 19mm wrench, an oil filter removal tool, a new drain plug washer, a roll of paper towels, a very large oil pan or bucket, and six liters of oil. Start by driving the car around and let it heat up to operating temperature. You'll want to empty your oil when it's hot, because the heat makes the oil flow a lot easier. More particles of metal and dirt will come out when the oil is emptied.

You will need to safely raise and support the vehicle. Please see our article on safely jacking up and supporting your Porsche 944

Place a large catch pan or bucket below the drain plug on the lower right side of the motor.
Figure 1

Place a large catch pan or bucket below the drain plug on the lower right side of the motor. Use a 15mm socket or wrench and remove the drain plug (red arrow). This plug should not be on overly tight, the specs are 37 ft-lbs but for some reason people like to really crank these on.

Use care as the flow of oil out from the pan will change as the level gets lower (red arrow).
Figure 2

Use care as the flow of oil out from the pan will change as the level gets lower (red arrow). Do not just remove the plug and place a bucket under it and walk away, or you may come back to a big mess.

There is a magnet on the end of the drain plug to collect any metal shavings or pieces in the oil.
Figure 3

There is a magnet on the end of the drain plug to collect any metal shavings or pieces in the oil. A small amount of fine metal or sludge is completely normal (red arrow).

Clean the plug (red arrow) and always install a new washer (yellow arrow).
Figure 4

Clean the plug (red arrow) and always install a new washer (yellow arrow). I always like to reinstall the drain plug before I move to the top of the motor to work on the filter. This helps to not forget to install it later.

The oil filter is located on the front right side of the motor.
Figure 5

The oil filter is located on the front right side of the motor. It is hidden down below the distributer cap by the power steering reservoir (red arrow).

I have removed a bunch of components so you can see the filter better but you do not need to do this to perform the work.
Figure 6

I have removed a bunch of components so you can see the filter better but you do not need to do this to perform the work. Place a type J oil filter removal cap (red arrow) on a long extension and make sure it is seated well on top of the filter. Remove the filter. Again the filter only needs to be snug on the housing but for some reason people like to really torque these down

Remove the old filter.
Figure 7

Remove the old filter. No matter what you do you are going to spill some oil, so be prepared to catch it under the car as well as clean up around the housing. Make sure to inspect the old filter for any metal. Before installing the new filter, use your finger and put some clean oil on the rubber gasket around the base of the filter (red arrow).

Check the condition of the housing for any dirt or debris and clean up any spilt oil (red arrow).
Figure 8

Check the condition of the housing for any dirt or debris and clean up any spilt oil (red arrow). Install the new filter and torque to spec, being sure not to over tighten. If you do not have a torque wrench hand tighten it then give it a 1/4 turn with the wrench.

Remove the oil filler cap (red arrow) located just behind the intake manifold and add the appropriate oil.
Figure 9

Remove the oil filler cap (red arrow) located just behind the intake manifold and add the appropriate oil. Start by adding 5 liters until it reaches the max mark on the dip stick. Start the motor, which will pump oil into the filter and let the vehicle run for a few minutes. Turn the motor off and let it sit for 5 minutes and then check the level and add oil accordingly.
