Review on Fumoto F107SX M12-1.75 SX Series Engine Oil Drain Valve by Daniel Jackson

I thought it would be great if my frequent oil changes could be made easier and less messy. I hadn't planned that the oil change would take all day. On a 60°F day with an oil temp of 70°F, it took over an hour just to drain the oil. The valve size is MUCH small to allow oil to pass through at ambient temperature in a reasonable amount of time. Heck, even 15 minutes would be acceptable. I don't like the idea of starting the engine hot to drain the oil in 15 minutes - oil at 220F removes a lot of wonderful layers of skin.
