Have any of you guys used this Fumoto Engine Oil Drain Valve, and what do you think about this product? I've been told it is a lot better than the Fram Sure Drain, I guess it does a good job of dispensing the majortiy of the old oil. I like the idea of changing your oil without getting messy, all you have to do open the spring activated lever, that's it. How reliable is the spring activated lever, like off-roading etc.? They also make one with a nipple, so you can install a hose to drain the oil into a milk jug, does this nipple stick out much to where it would hit anything? Any opinions and advise would greatly be appreciated. Thankyou!
