I use an extractor every other oil change. This is because I change the oil at 3,750 mile intervals or so and the oil AND filter every 7500.

The capacity is just over 5 quarts with filter and I get about 4.8 - 4.9 quarts out with the extractor. If you factor in the oil in the filter, I am only missing a small amount of oil from the pan. The key is to make sure you've inserted the tube down the dipstick to the appropriate depth. You have to play around and feel for when it starts to bend upwards. Near the end of the extraction - move the tube up and down a bit to see if it starts to drain out a little more. Do this from different depths until you are sure that the tube has reached everywhere that it could.

I have one of the cheap $45 ones that i found on ebay - it is powered by connecting to the car battery.
