THOUGHT I'd let you know that my 1995 Holden Caprice V8 has done 426,000km on LPG. It gets 6.7-litres/100km on the highway and 10.4-litres/100km overall, and to this day does not burn oil. My old VN is still going well at 500,000km on LPG. I am often asked if you can put a four-cylinder on LPG and I say, yes, that in New Zealand many cars are on LPG, CNG (compressed natural gas) or fuel oil.
YOU'RE doing well, and you're right that any car can be made to run on LPG. But while you can walk into most installers and buy a system for a Falcon or Commodore, there are few systems for four-cylinder cars.
