Propane is nontoxic, colorless, and virtually odorless; an identifying odor is added so it can be detected.

Propane is primarily a byproduct of domestic natural gas processing, though some propane is produced from crude oil refinement.

Though historically associated with other crude oil products, such as a gasoline or diesel fuel, propane differs from these fuels in several critical ways: -Affordable: Propane prices have fallen relative to gasoline, diesel fuel, and home heating oil due to the growing supply. -Cleaner: Propane is a cleaner-burning, lower-carbon fuel than other petroleum-based products such as gasoline or diesel because it burns hotter and more efficiently.

Propane is used in millions of households as well as many businesses for water and space heating, indoor and outdoor cooking, clothes drying, and backup power. Additionally, many industries increasingly choose propane to cost effectively fuel vehicles and equipment while lowering emissions. On-Road Vehicles.
