sick of draining the oil in my argo into the tub and having to let it run out the water drain at the rear, and too cheap to buy a marine extractor, i came up with this simple tool. i took a piece of tubing that would fit down my dipstick tube, crammed it into a chunk of 1/4 fuel line, then drilled a hole in a hard plastic water bottle and stuck the other end of the fuel line in the hole. make sure it's a tight fit or use silicone adhesive to seal it up. ( i put the fuel line in just far enough for it to be angled down, so i can see the oil running into the bottle). just put the tube down the dipstick hole till it hits bottom, and put a shop vac over the top hole in the water bottle... oil is sucked out, but doesn't run into the shop vac. i first tried it with a soft plastic bottle, and it worked, but tried to suck the bottle shut. hard plastic is the ticket. takes it a few minutes to suck an engine empty, but still faster than cleaning out the tub. i only used the fuel line because i didn't have enough of the small tube... it should work with just the small stuff if it gets sealed to the bottle well. just thought i'd share
