I have had one on my truck for years and it has been great.
Unlike any other engine I have owned, the oil plug required a washer every oil change or it would leak.
The Fumoto stopped the need for a washer and made an oil change that much easier/faster.
The drain also makes it easier to take an oil sample without making a mess.
Even though it would be almost impossible to have the drain value opened by hitting road debris, I use a wire tie to lock the value in place.
