Question: are lpg and propane the same thing?
Answer: The chemical formulae of both Propane (C3H8) and Butane (C4H10) are quite similar. Both are hydrocarbon gases and both are Liquefied Petroleum Gas. Propane and Butane are both LPG by themselves, but are two separate elements completely. ... Autogas is either a pure form of Propane or a mixture or Butane and Propane.
