I have a TC that has been sitting for about 2 years. I have it sold and am trying to make sure everything works before the new owner picks it up. I tried to start the Onan propane powered generator and it would not start. I acted like it was not getting fuel. I tried to light the stove inside and nothing came out with the burner control turned on. I finally disconnected the low pressure side of the regulator, I had gas coming out of the regulator. From the line I disconnected from the regulator I had about 3 tablespoons of oil run out. I have no idea where it came from, or what it is.

Help!! Ideas of what it is and what to do to get things running again.

Thanks

There is oil in propane. If you can heat the lines any oil should come out or try blowing them out with compressed air. Just watch for low spots and have a hose into a container by the generator and someone holding it. On our Big Buddy heater that I run off a 20# tank I have a oil filter so it does not plug everything up and they recommended it in the instructions.

Propane sitting in the lines can create the sludge.
It is possible all the orifices of your propane appliances are clogged with the stuff and may need to be cleaned out.
You might need to purge and clean the tanks.

Oil is often added to LP gas to prevent freeze ups.

WHERE did you get that incorrect info?????? NOTHING is ever added to LP except the ODOR (mercaptan) agent. Think about it. HOW would OIL prevent freeze ups??? Doug

I had an issue with an oil type sludge in my propane a few years back. Plugged off my camping stove and had to strip everything down to clean it out. Got home disconnected the tanks then ran wood alcohol with compressed air through all the lines and cleaned everything out. Never had an issue since.

Oil is indeed in propane and is usually the cause of eventual regulator failure.

Oil is a byproduct of the process of making LP from OIL, but OIL is not added to LP. LP is made from crude oil. Doug

As a commercial balloon pilot, I have burned more propane in one year than most of you have in a lifetime. Yes, propane does have a " lubricant" in it in the form of either propylene or butylene. The smelley portion is either ethanethiol or thiophene

The smelley is actually emitted by flies when they are looking to mate. That is the reason flies like to hang out around fueling stations and whenever you have a leak.

It's a toss up which is the more potent bear attractant: LPG or frying bacon. Want to cause panic? Soak a rag with the oil and stick it in the middle of a camp of boon docking RV's.
