Default Motor oil

Did i read it right the 991 has more than ten liter of motor oil? Why the increase? Thought the 997.2 engines were generally carried over tomthe current year?

Quoted from the 2012 Tecknik Introduction for the 991, pg 7

"The engine is filled with approx. 10.6 qts (10 liters) of engine oil, the change quantity is approx. 7.9 qts (7.5 liters)."

This is about the same for the change quantity for the 997.2 3.6 liter engine. Looks like there is oil that doesn't come out for both engines when you drain the pan and change the filter. This probably varies which is why a lot of the members recommend measuring what comes out and putting that amount back in.

If I find more references, I will post it to this thread.

Maybe they mean change quantity without changing the oil filter?

Wow. That would seem to be pretty important especially for the independents a lot of people use to service their cars.
