If your oil plug faces down at the very bottom of the pan like mine, I would not recommend this at all. The short version: It doesn't drain all of the oil. At first, this seemed like a great idea to me. I was a little nervous about the valve accidentally opening but convinced myself they had thought of this themselves when they designed this thing, so I went ahead and installed on on my car. I like that I can attach a hose before I open the valve and don't get any splash or get my hand drenched with hot oil. I figured this was a really great idea but I always wondered why manufacturers didn't use this from the factory. It made me a little nervous that it is hanging down there just asking to get nocked off but in reality, this would probably never happen except in an accident or something and I would know about it before the engine was damaged. A few months later, I went to replace the oil pan gasket so I drained the oil using this valve and removed the bolts around the pan. I noticed that when I tilted the pan, more oil drained even though the drain is located at the very lowest point in the pan. Then when the pan was removed, I saw why this was happening. It did not drain all of the oil. The valve extends into the pan. The drain valve threads into the hole in the bottom of the pan, but it also extends through the hole, in my case by about 3/16". So when you open the valve, all but the last 3/16" of oil is drained, not ALL of the oil. Also, any thing heavy (carbon chips, metal chips) stays in the pan instead of draining out with the oil. I could modify this by cutting the threaded part shorter but it's brass and I'm afraid there might not be enough threads to insure it stays tight. In short, I'm going back to a drain plug. The drain plug drains about 3 - 4 times faster than this valve and I'm sure that all of the oil gets drained.
