Hi all, not been here for a while since my 5.0 t topped GTA days back in the noughties, now the boys have left home and Im a handful of years from retirement, Im now looking for some fun again. Im looking at a 5.7 GTA ,auto trans, got around 156,000 miles on but looks in good condition.
my question is, it has had a LPG conversion done, the engine has had a recent service and lots of history, I guess the lPG conversion was for fuel economy, is there any loss of power or worries about it?
I had a unit near a barn and my landlord had a LPG converted Land Rover, it had a slight leak in the system. One night a fridge or charger clicked in and the whole barn went up in flames.

 

I have never owned an LPG conversion, but looked into it seriously years ago. Determined there was a significant power loss and too many other associated problems and abandoned the idea. They can be converted back though.

 

thanks Aaron, thought there may be some loss,our local LPG station has closed , its harder to find LPG stations than charging points here now.
he has also removed the ac pump so more work to do, might have to look at others then.
my 5.0 came from Florida , we saw it on vacation and the gas station owner that was selling it had a brother at Jacksonville who got it on a ship for us , my next task, find one and export.

 

I ran a 70's pickup back in the 80's that I converted to LPG. Performance was about the same as gasoline however fuel much much cheaper. Having a 300 liter tank the the box of truck made fuel stops a long way apart. Fuel capacity in any car is very limited due to space limitation for the tank so you would be refueling often. Cost of LPG has skyrocketed since the 80's when they started putting road taxes on the fuel. When LPG is now roughly the same cost as gasoline, it easier to just run gasoline.

When I was buying propane, gas was around 30 cents a liter and it's now close to $1. At the time, propane was running around 8 cents a liter. Now it roughly the same price as gasoline. Propane production has nothing to do with a barrel of oil. Propane is a byproduct of natural gas production but pump prices keep changing as oil keeps changing.

There are also a lot less gas stations that provide propane. Back in the 80's they were everywhere and you could easily drive across the country knowing you could find propane at just about any station. Now you would need to plan ahead to know if you can get to another station.

Propane is an excellent fuel. Extremely low emissions (propane powered forklifts run around inside buildings). Easy to start when cold because vapor is being put into the engine instead of liquid like gas that has to vaporize. No float bowls, No accelerator pumps etc. Downside is the size and weight of the fuel tank. Never really popular for cars. You also can't park in any underground parkaid because propane is heavier than air and if there is ever a leak, it will sink to the bottom. Propane powered tow trucks can't go into an underground parkaid.

In the 70's and 80's converting to LPG was relatively cheap and easy and the government even paid an incentive to do the conversion. The government also killed wanting to do a conversion with things like increasing the road taxes to make the conversion worthless.
