I changed my oil & filter over the weekend. The oil I drained pretty much filled half of a gallon jug as normal. After I replaced the filter I filled it back up. I didn't even get a full quart in & it overfilled & ran down the frame. After cleaning everything up, I ran it up & down the road figuring the oil would get sucked wherever it needed to be. When I checked, it was still full. I'm not the smartest duck on the pond but I know this thing takes twice as much oil as I was able to put in. Any ideas?
