Converting Your Car To LPG (Liquid Propane Gas)


With the price of gas these days, it’s hard not to feel like you’re getting violated every time you pay at the pump. And the cost of a hybrid vehicle can make you feel like some of your options are out of reach. But there is a way for people of normal persuasion to help the environment and save a little money at the same time. The answer to the question you’re all asking, “what is it?”, is liquid propane gas (LPG). Who knew strapping a propane tank to the trunk of your car could be so cool. Hank Hill would be having a conniption!


I can’t find anywhere, in my area at least, that provides the service of converting. Apparently this is already big business over in the UK as there are all sorts of British companies and institutions who use it. They even have over 1000 LPG pumping stations built into their infrastructure.


The Benefits: Emissions are less harmful, it’s less expensive, and LPG burns cleaner causing less harm and wear to your engines internal combustion components. There’s a website in Britain that will calculate how much money you can save by making the switch to LPG. Considering the pound is valued more than the dollar I thought the savings may be substantial… and I was right. My savings of 944 pounds converts to $1,870.00 driving a 1995 Toyota Camry with 136,000 miles an average of 10,000 miles annually. I had to hack a London restaurant phone number (courtesy of UK Yellow Pages) and post code (courtesy of Wikipedia)into the information section to get an output on cost of conversion, and I came back with a cost of 1915 pounds, or $3,795 dollars (using Google converter). But they also provided a cost analysis (brilliant Brits)which told me that my 4 year return on investment would be about 50% (in pounds and dollars), and that over that same 4 year period I would save 3,779 pounds or $7,490. I would also be helping the environment by reducing my carbon output by 1.56 tonnes which in the states is 1.72 tons, and I normally emit 6.6 tonnes, or 7.3 US tons by using a Co2 emissions calculator. Thats about a 24% reduction in emissions if my math is correct, but I’m a psych major, so I might be wrong.


You can also claim a deduction on your taxes for the cost of conversion, so it’s pretty much paid for. We have to take into consideration the fact that the Brits buy their fuel by the liter, or litres as they say on the island, and pay more for it. Since we pay less for more gas, this may throw a wrench (or turd in the punchbowl, stick in the spokes) in the huge savings I encountered.


You can purchase the components from a couple different companies, here and here.  If you’re handy with a wrench, or know someone who tweaks on cars, you can no doubt do what 9,000,000 other people in the world do and run your car on LPG.


This guy has a site with instructions on how to convert an Imperial, but there are no doubt websites with instructions on how to do it for your car and as he says, anyone whose got a reasonable degree of mechanical ability can make it happen.
