Yesterday at Pep Boys I ran across Fram's Sure Drain mechanism for changing oil for $9.95. Seems like it would make things a lot less messy during oil change, but wondered if there was any down side that any of you might have discovered? In essence, it is a permanent replacement for the oil drain bolt, with a twist mechanism which opens the bolt to open the channel and drain the oil, and a small hose which goes on at the time of the oil change. Once you put the hose on and point it into the proper receptacle, you turn the new oil drain bolt to the open position which starts the oil pouring through the hose. Once drained, twist the new oil drain bolt again to shut it off, take off the hose and you are done. Seems almost too good to be true! Any experience or comments?
