Jul 17, 2017 · Liquefied petroleum (LP) gas is propane mixed with butane and placed under pressure to liquefy it. The energy content of LP gas is 91,000 BTUs per gallon. Thus, a 40,000 BTU BBQ grill burner using propane at 80 percent efficiency uses (40,000 / 91,000) /0.80 = 0.55 gallons of propane per hour. Don't confuse device efficiency with burner efficiency.
