On the shopping list - oil sump valve

Bio users change their engine oil at a regular 5-6k miles. For me this means getting the car up the ramps, removing the splash guard etc. I found a website called "quickvalve" and they make sump valves to replace the plug. All you do is turn the tap, drain the oil and refill - perfect! I think you can make something from standard plumping/gas parts. The local hydraulics shop is on the case!
