I'm in the Netherlands and I think 80% of the amazons and 140/160's run on Liquefied Petroleum Gas, or LPG. Over here it's a mixture of propane and butane I believe, mixing ratio depending on the season.

Over here petrol is about $ 2,00 per liter, LPG is about $ 0,40 ....

LPG has less energy per liter then petrol (regular petrol has about 33, while LPG only has about 25 * 10^9 Joule / m^3. Because of this, a lower milage seems obvious. However, since the LPG is already vapourised in a separte vapouriser, the air/fuel rmixture is excelent and makes up a bit. In practice you'll need about 10-15% more LPG then petrol. The car is a tiny bit slower in the low rpm range though.

cheers, ben

btw1. Keep in mind you will need hardened exhaust seats. LPG has a higher operating temperature, so valve seats wear out quicker. Without hardened seat, you might be able to run 50k miles still though.

btw2. LPG has a lot less harmfull exhaust fumes, environmental-wise, which in my opinion is a small, but extra advantage.
