Conversions are expensive, you get reduced range and power, filling stations are few and far between and the cylinders take up space.
Compressed Natural Gas.
CNG is short for compressed Natural gas. The same as what you use in your house.
There are cars that run on diesel, CNG (Compressed Natural Gas), LPG (Liquefied Petroleum Gas) and electric power.
gasoline, diesel, CNG (compressed natural gas), Propane (forklifts-not normally cars), Hydrogen gas, coal/wood for steam powered cars.
Compressed air or compressed nitrogen.
CNG, basically used for Compressed Natural Gas and comprises mainly of Methane or Propane.it is mainly used in cars and many vechiles
Diesel, CNG( compressed natural gas), hydrogen, Electric, biofuels, solar, human powered(bicycle).
Air compressed cars are cars powered by compressed air. A compresser is used to generate high pressure air, and that air is then in turn used to propell the car. An electric engine and or a gas engine is still needed to run the compresser but unlike hybrids and other combination vehicles the air compressed cars use either of these engins to power the compressor only.

CNG (compressed natural gas) is better because it's a cheaper kind of gas, and you get more MPG (miles per gallon) out of it.

You can't convert natural gas to propane because natural gas is methane and propane is what it says it is. Given that, there are Compressed Natural Gas cars, and if you get a natural gas compressor you can use it in a car.
