The mercaptan odor has been added specifically to assist in the detection of leaks.
If odor from the gas is noticed, the implication is that you have a leak. Attend to it promptly.
Varieties of LPG bought and sold include mixes that are primarily propane (C3H8), primarily butane (C4H10) and, most commonly, mixes including both propane and butane, depending on the season - in winter more propane, in summer more butane. So that people can smell the gas (for safety) chemicals that smell are added - ethanethiol, thiophene and amyl mercaptan.
When was mercaptan first added to gas in the U.S.?
Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season---in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN 589
The natural gas supplied by your utility company is almost pure methane. This is a chemical compound of one carbon atom and four hydrogen atoms.The stuff that comes out of a natural gas well is a mixture of hydrocarbons (mainly methane, ethane, propane, and butane) and impurities. All of the stuff besides methane is separated out (and something smelly like mercaptan added in) before the natural gas is sold to consumers.
ethyl mercaptan
Liquified propane sold as fuel in the US must be at least 90% pure propane; the rest is typically butane, propylene (5% maximum) and ethyl mercaptan, which is added to give it a noticeable and characteristic odor.
When produced propane and butane is odorless and colorless. Ethyl mercaptan is the odorant added to propane and butane in the processing and refining process to provide a detectable odor. Under certain conditions the odorant in propane may oxidize and lose its destictive odor. This odor fade can occur in new steel containers when first placed into service and in older steel containers that have been left open to the atmosphere. Air, water, or rust in a propane tank or cylinder can also reduce propane odor concentration. Ethyl mercaptan is toxic although the amount added to propane is non-threatening.
Propane and butane. Some methanethiol (methyl mercaptan) is also added, giving a characteristic putrid smell to easily detect leaks.
Yes, Liquified Petroleum Gas is a Gas. It is a mixture of butane and propane. Also ethyl mercaptan is added to LPG to detect the gas leakage.

It has no odorAnswer:C4 (Butane) has no odor on its own but has odorous materials (Butyl- or methyl- mercaptan) added for leak detection.C-4 (the explosive) has a faint bituminous (oily) odor.
Green gas is just propane with some oil added to it. You can get a propane adaptor and use propane. Edit: The oil in question is silicone oil. Also, propane often has an additive called ethyl mercaptan, which causes its pungent smell. Green gas generally has a less strong smell, or none.

Propane itself is totally odorless. But due to its extreme flammability, a tiny amount of a highly potent "odorant" gas (usually methyl mercaptan, which smells like rotten eggs) is added before sale for safety. It is not practical to remove the "odorant".
