Had the Fister Sport Exhaust modification added to my 997.2 Cab. Love the new sound!

So what's the consensus? Oil overfilled at 8.5 quarts? Siphon out one qt?

Q 997.2 C4S

Bought gas. I always let the pump tell me when the tank is full with the auto-shut-off. Got exactly 9.97 gallons.


9.97 gallons exactly!

I'd remove the qt then make sure the car was level and check everything carefully.

If your going to do your own changes in the future and don't have a lift, I recommend two jackpoint stands and two esco stands. I've been using them for a little while now and changing the oil is quick and easy without any hassles.

Thanks Jacu

Ok tried but it doesn't seem possible to siphon out oil through the fill tube unless the plastic tubing I tried to use was too stiff. I pushed in gently until it ceased but never reached oil.

Took the car out for a spin after applying ceramic coating, trying a new rim color, replacing brake pads, spark plugs, coils, and pressure testing.

Yep, that's it. Worked like a charm. No leaks now!

I use two 2x12's under each wheel when I change the oil (last night).
Easier than jack stands. Plenty of room to access the drain plug and oil filter.
If it were me, I would remove the oil filter canister and pour out (or save) that oil.
Might have to do it three times or so to get half quart.
Could loosen the drain plug and drain it also. But then you risk having a crush washer that leaks some.
Keep us posted on your results.

Dude. Awesome video! Any chance you're in Houston?

Great news. Want to sell the RMS install and clutch alignment tool or are you keeping them for future projects?

OK, found this on page 335 of Porsche owners manual , Capacities:
911 Carrera, 911 Carrera 4, 911 Targa 4: Oil change quantity without oil filter approx. 8.5 quarts / 8.0 liters
911 Carrera, 911 Carrera 4, 911 Targa 4: Oil change quantity with oil filter approx. 8.7 quarts / 8.25 liters
911 Carrera S, 911 Carrera 4S, 911 Targa 4S: Oil change quantity without oil filter approx. 8.7 quarts / 8.25 liters
911 Carrera S, 911 Carrera 4S, 911 Targa 4S: Oil change quantity with oil filter approx. 9.0 quarts / 8.5 liters

I have a 2009 4S so now I will stop worrying and consider this the definitive answer. So all those who were hanging their hat on 7.5 quarts with no documentation please take note

Odd that the same motor has different fill quantities.

I would still advise that you measure your oil level first. Measure the oil removed. Add the same amount removed plus or minus a bit to adjust for the measured amount before the drain (more of the measured was low, less of it was high).

What you DO NOT want to do is over fill. If you need 8.5 or 8.7 or 9 fine. But I would still advise that you measure first, measure the removed, and go from there.

I've found a consistent 7.5 quarts over an 85K mile stewardship using my method (18 changes).

We went out for a 450 mile spirited drive today and changed the oil in one of the cars upon our return ... 7.5 quarts. Same as several previous changes on his car.

Both of the cars mentioned above are 2010 C4Ss.

If you can point out a methodology flaw in the above please let me know.

BTW, dry system fill quantity is 10 liters. When you drain the oil you are draining only about 3/4 of the old oil. There will be oil remaining in the heat exchanger, pipes, internal sump, heads, galleys, pan, etc. Anyone stating that there is a specific amount to add without measuring the removed may have problems.
