I have a small propane heater, Mr Buddy, or something like that. I takes
a 1lb propane bottle.

I have made a long hose to connect it to my 5gal tank which is outside.

After only a few months the thing stopped working, pilot would not light.
I disconnected the gas line and then removed the regulator.
When I disconnected the low pressure side of the regulator
a reddish light grade oil came out. Lots of it.


Any idea what is happening and why?

My guess is somebody tipped over your outdoor bottle. If the red oil stinks like
ethyl mercaptan (skunk) that would be a tipoff. If the bottle tipped, then some
of that oil (which seems to be present in all propane, maybe it's a byproduct of
the way propane is refined) might have gotten into the regulator.
