The Fumoto Valve allows you to change your engine oil without any tools…provided you don’t do like me and install your oil filters to twice the required Ugga Duggas…. I’ve had them on many engines and have never had any issues. There is always a minute chance that the valve could be broken off by road debris and it may not be a good decision for every application. But the valve has always been adequately protected by skid plates or chassis components on my vehicles, so I’ve never had any concern
