One of our clients, P.Chuddy, sent over a great suggestion that adds another level of safety to our gPAN - but could be used on most of the oil pans. He adds a carplug over the drainplug fitting and secures it with a hose clamp(not shown in pic). This is a simple way to ensure that your drain plug does not vibrate out of the bung - which is not something we have seen. Better safe than sorry. Thanks Paul for your suggestion!
