I've searched for this and can't seem to find what I'm looking for. What is the difference in oil volume between the min and max notches on the dipstick? I notice that when my oil level gets down to about halfway or a little below halfway between the notches, I can start to hear a little valvetrain noise. Is that a half quart low, a full quart? When topped up my engine is quiet and smooth.

The owners manual on my 944 S2 says its 1.6 qt from the min to max notches.

So a little under halfway would be about a quart low then. Can anybody confirm from their owners manuals that this is the same for the turbo cars? Don't 951s have a slightly higher oil capacity than the S2 cars?
