Another Fumoto fan here.
And another tip. When using the Fumoto valve (nipple version) with a hose, you can drain it directly back into the jugs it was in when new. No need for a pan, except for the filter.
If one was so inclined, they could measure how much oil comes out with a pretty high degree of accuracy. People HAVE discovered problems early that way, without sending the oil out to a lab.
As for the Fumoto security issue... I don't worry about it. The drain plug doesn't have a lock on it either. I figure that if someone is going to slide under my truck with the intention of draining my oil.... He will likely have the wrench he thinks he will need to do it.
