I take 10'-12' of cheap 3/8" OD white poly tubing and run one end down the dipstick tube(fits perfect). I push the poly tube down until it touches the bottom of the pan and pull back ~1/4" and siphon 95% of the fluid out into milk jugs. This does 2 things; it makes pulling the pan MUCH more pleasant and I know the exact volume of what I took out. Therefore if the fluid level was correct before draining and I put the same amount back in, bingo...my level it right on the money without dinking around checking and adding all afternoon.
