Smile MPG

I HAVE OWNED MY CRUISER NOW FOR A YEAR , AND HAVE NEVER LIKED THE MPG. SO I HAD IT CONVERTED TO LPG, SPOT ON 50P A LTS. CLEANED THE AIR IDLE VALVE AND PCA VALVE.
ON GAS I AM KNOW GETTING 25 MPG AROUND TOWN. AT 60 MPH ON MOTORWAY 34.4 MPG HOWEVER IF YOU DROP DOWN TO 55 MPH MY MPG WENT UP TO 40.
I COVERED 270 MILES, 150 AT 60 MPH, TOPPED UP GAS =25LTS
THEN 120 MILES AT 55 , TOPPED UP GAS 15LTS

First, welcome to the forum. Second, please don't use all capital letters when on any forum because it symbolizes that your SHOUTING.

Most of us wouldn't have the foggiest idea how to convert an N/A engine to use LPG. Is there instructions on the process of converting? Do you have pictures of what the engine compartment looks like after the conversion? I take it the fuel tank has to be changed to hold the LPG gas?

There's loads of owners on the forum looking for better gas mileage so how about some more information.

By your screen name, do I take it your in Wales? The diesel PT is sold over in Europe and you never here anyone on the forum that has one complain about fuel mileage. How does that compare with LPG?

I'm surprised natural gas usually gives you less MPG, but it works out because it now costs less than oil/gas. I would love to see how you did it and what was involved, it would be cool to be able to do if gas keeps on going up again.

Hi, sorry about capitals; my car was fitted with liquid propaine gas the gas tank went where the spare tyre would have hung, the spare is now in the boot.
car can run either on petrol or gas, but starts on petrol for the first thew minits.however i try to avoid petrol due to the price 112 lts, compaired to 50p for gas.
the gas is injected into engine in the same way as petrol and it has it own ecu which links up with the cars ecu
trying to stop the engine running lumpy on tick over i finely found the problem,the air idle valve was not working to it best, a clean and a light oil also cleaned the pca valve, it was from doing these jobs that my mpg inproved (over here our gallon is bigger)
yes from wales uk

I wouldn't even know where to get Liquified Petroleum gas, so if I converted, wouldn't know where to fill up - and if I took a trip....

Years ago i drove a work truck that only used propane and after 200,000 miles the motor had to be torn down for rebuild due to oil pump going out. I knew the garage that did the work very good and got to hang out after work to see the insides.

It was unreal how new everything looked. Hardly no carbon on pistons, ports in heads looked new still.

Made me think about converting all my cars over but cost for kit and getting propane on the road kept me from doing it.
