I am planning to install the LPG Conversion Kit to my 2010 F150, since the cost of fuel in my country is averaging $4.00/gallon while LPG average $1.75/gallon. I figured that I can pay off for this conversion kit cost of $1500.00 within a year period given the mileage I drive within that same time.
However, someone told me that they lost an engine much quicker using LPG versus gasoline. This guy said that within a year and a half time he drove over 55000 miles and his engine was done. The rings for the piston in the engine along with the cylinder itself were heavily worn. He said he changed his oil according to the manual and yet the engine failed.
Can anyone share their experience with this type fuel please? I don't want to have that experience. I am thinking that his conversion wasn't done properly.
Thanks

 

This forum is mostly US-based, where LPG conversion is rare on passenger vehicles. You might try somewhere with more volume of those.

Having said that, I spent a couple years in the Netherlands where the conversion is really common, particularly on trucks. Seemed like a lot of classic Dodges were floating around with big LPG tanks. I had a few LPG cars (Opel, Renault, Audi/VW) and all was fine.

The caveat is LPG really doesn't put out as much power. Running the Opel Astra across Germany, I topped out at 180km/hr (~110mph) and switching to 89 octane dino-juice got me up to 205 (~125 mph). Those were the days - backseat laden with backpacker chicks and a trunk full of amazing Belgian beer.

 

There is a guy in the Los Angeles thread in the south west forum here that did the conversion.

 

We run a ton of LPG trucks/fords here at my work (AT&T) other than finding a place to refuel they have been pretty rock solid and many are getting up there in miles without issues such as you described. We also have generators that run LPG and they are actually a lot less trouble than their diesel/gas counterparts.

 

My buddy drives a LPG f150 company truck with six cyclinder, says it can't get out of its own way but reliability is normal.

I have talked to limo drivers running propane conversions up to 500k, minimal power loss and no durability problems.

 

I've been around quite a few GM 8.1 liter engines running on propane, for the most part they seem just as reliable as a typical gas engine. Propane doesn't have the lubricity that gasoline does, but as long as you run good engine oil you should be in good shape. As others have said, you wont have the power that you have with the engine running on gasoline
