So you’ve done all your calculations and decided to convert your car to LPG like over 700,000 other Australians. It sounds good in theory and the government rebate of $2000 is a great help. The fuel figures show your savings in dollars will have your conversion paid off within a year or two depending on your vehicle and the mileage done. But have you got all the facts?
The environment is another winner in the change you have made by lowering greenhouse emissions. The Australian Greenhouse Office website states that the mass of CO2 gas released of the exhaust pipe by the burning of one litre of fuel is:
- 2.3 kg for Petrol
- 1.5 kg for LPG.
LPG = Less kilometres per litre
You can expect a 20-30 per cent increase in gas consumption over petrol per kilometre because the lower energy content of gas requires more to be burned in the engine compared with petrol.
There is no government excise until July 2011. But then the price of LPG will gradually rise over 5 years.
The excise will increase as follows:
- 1 July 2011 initial excise of 2.5 cents per litre
- 1 July 2012 excise increases to 5.0 cents per litre
- 1 July 2013 excise increases to 7.5 cents per litre
- 1 July 2014 excise increases to 10.0 cents per litre
- 1 July 2015 excise increases to 12.5 cents per litre
In knowing all this, is or was a change to LPG worth it?
Do all the figures add up and, despite the cost savings, has your vehicle’s power and torque suffered? Is it less efficient when towing or carrying heavy loads, especially on long trips and going up hills?
