Yeah, I've had oil in propane tanks before. It was some kinda thin pitch black lookin stuff. Maybe it was some genuine crude oil. I never knew where it came from, and still don't it seems.

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.
You may be a commercial Ballon pilot, but you don't know JACK about LP. Your comment makes about as much sense as a commercial Truck driver that uses more Diesel in a year than a pick up diesel driver and then claiming to know more about Diesel than the pick up driver. For YOUR info. It is NOT added as a lubricant but added to let you know if it is leaking and present as the LP has no odor. Doug
ethyl mercaptan
A colorless organic liquid that has a very strong odor. It is added to odorless fuel, such as natural/LP gas, and fuel systems as a warning agent in the event of leakage or spills.
Plasticizers are manmade organic
chemicals such as phthalates and
fatty acid esters that are added to
materials to increase flexibility,
durability, and ease of use.
Plasticizers leached from propane
hose are yellow oily deposits that
are heavier than propane. They
could accumulate in vaporizers,
regulators, and in the bottom of
storage containers, and may
eventually compromise equipment
performance. In engine
applications, plasticizers may
contribute significantly to the
deposits in the vaporizer/converter.
I forgot to mention, to prevent an accumilation of any oily deposits in LP systems it is necessary to NOT mave any dips or loops in the low pressure LP lines whether they have copper or rubber hoses. The p trap dips or loops allow the oily residue to accumilate. So, if you look at your LP system reroute any hoses that have any such dip and remove any loops. Loops are usually found on motorhome ASME tank systems because they use a too long hose out of the regulator that attaches to the metal piping to the motorhome system and the Factory loops the hose rather than using the correct length or routing to prevent loops.

Same thing cowboy. Read below
Ethanethiol
Other names
Ethanethiol (EtSH), commonly known as ethyl mercaptan, is an organic compound with the formula CH3CH2SH. It consists of an ethyl group, CH3CH2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with S instead of O. The presence of S leads to many different properties, most notably the infamous odor of EtSH. Ethanethiol is also more volatile than ethanol due to a diminished ability to engage in hydrogen bonding. Ethanethiol is toxic. It occurs naturally as a minor component of petroleum, and may be added to otherwise odorless gaseous products such as liquefied petroleum gas (LPG) to help warn of gas leaks. At these concentrations, ethanethiol is not harmful.
