Is All Propane the Same?
Quick Answer: NO!
HD-5 is a specification which establishes a maximum concentration of 5% propene in propane. Propane and other LP gas specifications are established in ASTM D-1835. All propane fuels include an odorant, almost always ethanethiol, so that people can easily smell the gas in case of a leak. Propane as HD-5 was originally intended for use as vehicle fuel but has expanded as a requirement in MOST modern home appliances. HD-5 Propane is the ONLY Propane Town & Country Sells. We do not "Blend" our propane with Commercial quality propane. Never have, never will.
