My father-in-law gave me his old 1983 Porsche 911 SC. I am interested in learning how to work on cars, my only car experience is changing oil on my daily driver, but I am already confused by the oil change on this car. Please help with these questions:

1) I drained the oil out and there didn't seem to be as much oil as I expected (the owner's manual says 10 liters) - there was a fair amount of oil, but it didn't seem like 10 liters. I let the oil drain out for over an hour and warmed the car up beforehand.

2) I went to add the 10 liters of oil back into the car that the owner's manual says the car takes and after 6 liters, the oil seemed to be going in more slowly and I used the dipstick and it seemed to say that it was overfull with oil (although the car wasn't warm or started at this point, which the owner's manual says you should do).

Why would it seem that the car is already overfull of oil? Does starting the car make the level on the dipstick go down? (I know the owner's manual says the best test is with the engine running....but I was afraid I had screwed up and was afraid to start the car).

A second question is, it seems to be hard to get the oil filter out...does that hose that is in the way have to come off first?

I am embarrassed I am such a newbie, but you have to start somewhere!

Thanks for your help.
