Isnt that illegal ? using a vehicle on the road with fuel that hasnt had road duty paid ? bit like using red derv ?
And do you trust the government not to change its mind on LPG duty at the drop of a hat after the next election - there's a lot of money needed from somewhere and the motorist is always an easy target !

LPG duty is relatively more than petrol duty.. wholesale price is 19p/liter, the rest is tax ..
Liquefied petroleum gas (LPG), is the generic name for propane and butane gas. They are both a mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles
Why is it called Liquefied Petroleum Gas?
.... because these gases liquefy under moderate pressure and they readily vaporize upon release of pressure. At normal temperatures and pressures, LPG will evaporate. Because of this, LPG is stored in steel tanks. In order to allow for thermal expansion of the liquid gas, these tanks are filled between 80% and 85% of their capacity. The ratio between the volumes of the vaporised gas and the liquefied gas varies depending on composition, pressure and temperature, but is typically around 250:1. LPG is heavier than air, and thus will flow along floors and tend to settle in low spots, such as basements.
Where does LPG come from? LPG is manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground. There are several terminals situated around the coast of the UK. LPG is either delivered by sea tanker or piped in from offshore gas fields.
How will a supplier calculate the cost of LPG to an end user?
Typically based on the following:
* the current wholesale market price of LPG (quoted in $US);
* the cost per tonne payable to the terminal provider for providing the facility to store and collect the LPG;
* primary distribution costs from the terminal to the supplier's depot;
* secondary distribution costs from the depot to the end user;
* overhead operating costs;
* a margin or profit over and above the core costs.
