time it being overfilled by approx a quart, I have carefully measured and found that
3.2 qts is the perfect amount to not go over the full mark on the dipstick.
This is after draining out the old oil to the point it is dripping very slowly into a catch pan.
Also remember that some oil remains up in the valve areas and never drains out completely.
The motor is completely stock with factory oil pan and dipstick.
I read another post where a person found that 3.3 qts of oil was just right for his 2.4 Altima.

I also forgot to mention that in addition to the 3.2 quarts you need to add approx
another 1/8 quart for the oil filter capacity.
It cannot be 4.3 quarts as per the post below as the 4qts for the 2.4 is noting the
motor is COMPLETELY void of oil.
