The Porsche 911's flat-6 engine is a terrific piece of engineering that will last a long time if it is properly maintained. Part of that maintenance is, of course, the oil change. By following the steps below, changing the oil on 1998 and newer 911s is an easy task that can be performed in about an hour and save you a trip to the dealer.
Jack up the car using a floor jack and place the car securely on jack stands at all four corners using the factory jacking points.
Place an oil container under the oil drain plug of the motor.
Using an 8-mm allen socket, remove the drain plug at the bottom of the oil pan.
Let the oil drain thoroughly--this will take about 20 to 25 minutes.
Once all the oil is drained from the engine, install a new drain plug along with a new aluminum sealing washer. Tighten the drain plug to 37 lbs using a torque wrench.
The oil filter cartridge is located in front of the oil pan on the right side. With an oil filter removal wrench, unscrew and remove the cartridge. Be careful of spilling oil.
Install a new oil filter cartridge and O-ring. Before installation, run a bead of oil around the O-ring to lubricate it. Torque the oil filter cartridge to 19 lbs.
Pour new oil into the oil filler neck located in the engine bay. 1998 to 2001 911s (996) take 8.5 quarts, and 2004 and up take 8.25 quarts. Newer 911s (997) take 9 quarts. When filling the engine with oil, pour in 8 quarts and then use the dipstick to get the amount of oil exact.
Lower the car off the jackstands.
