Propane has a few advantages of gasoline, of course. It tends to burn more cleanly, itâs cheaper, etc. Still, nothing is perfect. Like any fuel, LPG/propane has some draw-backs that youâll definitely want to be aware of before you âpull the triggerâ and finally convert your car to propane.
Propane is a three-carbon alkane with the molecular formula C3H8, normally a gas, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, barbecues, portable stoves, and residential central heating.
