 | | It is commonly used as a heat source for engines, barbecues, and homes. |
 | | When commonly sold as fuel it is also known as liquified petroleum gas (LPG or LP-gas) and can be a mixture of propane with smaller amounts of propylene, butane and butylene, plus an odorant (ethanethiol) to allow the normally odorless propane to be smelled. |
