Yes I believe it is an inside job. I kind stood afar (to give then their "space") but saw the stream of oil stop. that's when I started to walk over. next time I will not be more than 10 feet away. what shocked me was it took less than a minute to refill it. that must be some high pressure oil coming thru or a very small amount of it.
It shouldnt take more that 20 seconds
I'm lucky it didn't just fall out on the highway.
just my .02
