And a spare regulator is a good thing to have.

It isn't expensive or difficult to install - and a lot of essential appliances in your RV rely on it.

Be aware that there can be a excess flow valve in the pigtail that connects to the tanks..

HERE

"Marshall Excelsior MER401-12 Excess Flow Pigtail 12 in Excess Flow Male POL, 7/8" Nut and 1/4" Male Inverted Flare connections. 12" HOSE Flexible thermoplastic UL and CGA approved hose. These hoses are rated up to 350 psig working pressure with a 400 pound pull test rating. Warning: An excess flow valve will not activate if there is a break or leak downstream of the valve that does not equal or exceed the closing flow of the valve or if the excess flow valve installed exceeds the flow capacity of the system. Each hose comes with two ends and fully crimped brass ferrules"

If if equipped with the valve it may have tripped or failed.. I don't know it is self resetting.. May have failed on both pigtails.

I use my Rv a lot. And I have had so many regulator failures that I always carry a spare.
I started doing this after one failed in camp on the North Rim. Temps were in the teens, and everything that runs on propane wouldn't work. I had to drive to Flagstaff and pay an inflated price for one.
Cost me 1.5 tanks of fuel and a day of hunting as well.

I've never heard of the oil issue. Interesting.

I know I installed new pigtails when I replaced both my tanks around the time of the regulator. My trailer still had the old style tanks, and I ran out of fuel. Had to get two of the new style tanks and switch out the pigtails. I'll check them out.

That doesn't sound like fun!

Propane since it is a "byproduct" of refining/cracking crude oil and natural gas into other products (at one time, propane, Naptha (cousin to gasoline were considered worthless byproducts and was flared off at the well head in the early days of crude oil production) which can contain small amounts of oil. Generally very harmless but since the actual content can vary some depending on how much processing has been done may be enough to make it out of the cylinder as you consume the gas (liquid form in the cylinder converts to gas as you draw it out of the cylinder).

I don't think so. Or, at least not all of what you said. What they were burning off at the well head was Natural Gas . That is not the same as propane ( Also known as liquefied petroleum gas (LPG) ) which is made during the oil refining process.
