Google "propane contamination" and you will have plenty of reading. While propane is thought of as a clean fuel, apparently quality control is lacking.

You could call it "propane contamination" if you prefer. I prefer to call it adulteration. Natural gas, LPG, and propane are normally odorized with very small amounts with a chemical (gas) called methyl mercaptan which smells like rotten cabbage/eggs or a confined area which lacks freshness after someone breaks wind. The odor threshold is in the low PPB, that's Parts Per Billion so human olfactory glands (your nose) approaches that of dogs when methyl mercaptan is present. It's used to warn users of a gas leaks. Methyl mercaptan oxidizes easily and combines quickly with water to form gums and varnish which can plug propane lines, pressure regulators, shut off valves, etc. That's why its very important to ALWAYS keep some pressure in your propane tank and NEVER leave the system open to the atmosphere unless you want to go see Doug, . . . . . regularly. Generally, changing propane tanks regularly because they are too small (invites contamination) is not a good idea and should be avoided if possible.
