Symptoms and effects of unchanged oil

Lubricating your vehicle is important for the health and functionality of every moving part. Oil has an essential role in this process because it acts as a protective barrier between metal surfaces.

Over time, that oil breaks down and becomes contaminated with dust, dirt, and debris from the engine and its environment. When this happens to your vehicle’s motor oils ability is compromised, which leads directly to speeding up wear on parts essential for function such as bearings or bushings within mechanisms like timing chains.

Proactively changing a vehicle’s oil and filter will help the engine continue to work at its best, as well as prevent costly repairs for drivers down the road. Changing it with higher quality brands like LIQUI MOLY will help to improve the overall health of your engine with the added benefits of having longer intervals than normal synthetic oils and better performance and fuel economy.

Changing the oil in your car is also a great way to spend your time with the car, and address little issues that can build up. In the long run, you’ll be more than glad you did it!

Steps required to complete a Porsche Boxster 981 MA1.22 oil change

Tools required for an oil change on a Porsche Boxster 981 MA1.22

  • 8mm Socket
  • 13mm Socket
  • 74mm or 76mm Filter Wrench
  • Torque Wrench
  • Floor Jacks
  • Jack Stands

Step 1 (optional): Clean the engine

Open the engine cover and pour one bottle of LIQUI MOLY Oil Sludge Flush into your car. Close the oil cap before you start, then turn on the key and let it idle for 10-15 minutes. We always clean up the engine with Engine Flush because it will significantly help the new oil and also enhances the engine compression.

Step 2: Change the oil filter

The oil filter housing sits in the back. Use the 27mm socket to remove the cap and filter.

Pull the old filter off of the cap and clean the cap with some parts cleaner. Then, remove the o-rings from the cap and exchange them with new ones.

Dress the new o-rings with some new oil and install them onto the oil filter cap. Slide the new filter onto the cap and then reinstall it into the engine.

Start to thread the cap into the housing by hand to prevent any cross-threading. Then, use the 27mm socket to torque the cap to 24Nm.

Step 3: Drain the oil

To avoid a vacuum during draining, open the oil fill cap and close the engine cover. Place it securely onto jack stands so you can lift up on both sides of the car without worrying about falling down. Use an 8mm socket for removing fasteners that hold splash shield in place (holds water away from internal components).

When removing the splash shield, don’t look up as it will be surrounded by dirt and debris. Place a drain pan under the drain plug. Position it farther toward the driver’s side as the oil will shoot out in that direction. Then use a 13mm socket to remove the plug.

After all the oil has drained make sure to clean off the drain plug and place the new copper crush washer onto it. Then, thread in the drain plug by hand to prevent cross-threading and then use the 13mm socket to torque the plug to 30Nm.

Reinstall the splash shield using the 8mm socket.

Step 4 (optional): Fill the ceramic coating additive

Shake the ceramic coating additive LIQUI MOLY Cera Tec

Open the engine cover and remove the oil filler cap. Then pour the additive into the engine oil tank. This coating will greatly enhance the overall performance of your car and ensure that all seals are solid and all parts are well protected.

Step 5: Refill the car with oil

Head into the engine bay and remove the oil filler cap. Then, pour in 7 liters of LIQUI MOLY Leichtlauf High Tech 5W40 oil. It takes some time for the oil to move into the system before you can check the oil level. Wait 5 minutes and check the oil level on the dipstick. In the case you did Step 4 and added the LIQUI MOLY Cera Tec, please keep in mind that the 300ml can be counted and deducted from the 7,5 L engine oil volume. Also, another option is to add the LIQUI MOLY Oil Saver which helps to increase the overall performance of your engine and the oil effectiveness. Simply add this to your engine oil by pouring it after adding the initial 7 litres.

Depending on the result of the dipstick add in small increments of around 200ml until the engine oil is at the MAX level of the dipstick. Don’t overfill the engine oil! This can cause smoke and other negative side effects. Use a workshop paper towel to clean up any spills you may have made.

Step 6: Reset the service indicator

Sit in the driver’s seat and put the key into position one. Then, hold down the two center buttons on the steering wheel.

Select “Assist Plus” from the menu that appears on the center instrument cluster screen. Confirm that you’ve completed a full service and then hit “OK” twice. The service interval is now reset.
