An aftermarket conversion is a vehicle or engine modified to operate using a different fuel or power source. Conventional vehicles and engines from original equipment manufacturers (OEMs) can be altered to run on fuels like propane, natural gas, or electricity.
Many OEMs offer alternative and advanced vehicles. However, the availability of certain models, fuels, and technologies can vary. This makes vehicle and engine conversions a good option to explore as a way to reduce or eliminate petroleum use.
All vehicle and engine conversions must meet emissions and safety standards instituted by the U.S. Environmental Protection Agency, the National Highway Traffic Safety Administration, and state agencies like the California Air Resources Board.
