From the 06 service manual:

Note that while they disagree, neither says 6 quarts. The owner's manual says 6.5 quarts, and the service manual says 6.9 quarts. My own experience is that 6.9 is right, because 7 quarts brings both of mine to the max fill line.
A few points here:
Max fill is better than min fill because the oil level can only go down, not up. (If it's going up, you have far more serious problems than a high oil level.)
It should take more than 8 quarts for there to be any chance of the crankshaft hitting the oil, and then only at an incline.
There are baffles above the oil pan so that even if the crank did hit some oil, it wouldn't be able foam up the oil down in the pan.
I always thought that the problem with foaming the oil was that the oil pump couldn't make pressure trying to pump foam.
