Follow these steps carefully
The 2003-2010 Cayenne V8 (4.5L and 4.8L) takes about 9 US quarts (8.5 liters) of full-synthetic 0W-40 or 5W-40 meeting the Porsche A40 specification - the A40 approval on the bottle is what matters, not just the viscosity. Buy 10 quarts so you are not short. The filter is a cartridge element in a housing on TOP of the engine, on the driver's side.
Idle the engine for two to three minutes so the large oil volume warms and drains completely, then shut it off. Pop the hood and locate the cartridge filter housing on the driver's side top of the V8.
Now the critical Cayenne detail: remove BOTH drain plugs, not just one. The V8's pan has two drain points, and draining only one leaves roughly a quart of dirty oil behind - which is exactly what the old version of this guide got wrong.
Lift the loosened filter housing cap off from the top of the engine and pull out the old cartridge element, noting its orientation. Wipe the housing and cap clean and inspect the housing for cracks. Fit the new cartridge element into the housing.
Do yourself a favor like I do: I wipe the housing and cap clean and inspect for cracks — the plastic gets brittle with heat cycles on these V8s.
Reinstall BOTH drain plugs, each with a NEW crush washer - never reuse the old washers on this engine. Tighten each plug to 37 ft-lbs (50 Nm), the Porsche specification; the old 30 Nm figure some guides cite is incorrect and will leave the plugs under-torqued. Double-check that both plugs are in and tight, then count them once more before refitting the panel - it is embarrassingly easy to reinstall one and forget the second.
Trust me on this one: Reinstall BOTH drain plugs, each with a NEW crush washer - never reuse the old washers on this engine.
Set a funnel in the filler neck and pour in 8 quarts of A40-spec 0W-40 or 5W-40 to start. Reinstall the filler cap.
Wait three to five minutes for the oil to settle, then check the dipstick twice: pull, wipe, fully reinsert, read. The level should sit at the full mark, never above. Top up in small amounts until the level sits at the full mark. Start the engine and idle for a full minute, watching the oil-pressure warning go out and looking underneath for drips at BOTH drain plugs and around the filter housing. If you do not have a Porsche-capable scan tool, many independent Euro shops will reset the service reminder for a small fee.
I've done this job enough times to say it plain: If you do not have a Porsche-capable scan tool, many independent Euro shops will reset the service reminder for a small fee.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
