The only issue I had with refilling is that the upside down positioning allows 'oil' to transfer to the smaller tank. This led to fouling in my Buddy heater.
there should be absolutely no OIL in a propane tank if it has been filled properly. Propane has no oil added to it.
They don't purposely add it, but it's there. The oily residue, called "heavy ends", is a byproduct of the refining process, and it's been fouling LP regulators forever. Mr. Heater makes a small inline filter for use with their heaters to avoid the issue.
