Because of the much lower duty on LPG, running costs are nearly halved. For an average car user, the cost of conversion can be recovered in less than 2 years.

The following chart shows the typical cost saving of vehicles averaging 20, 30 and 40 miles per gallon.

The Government is committed to increasing duties on petrol and diesel by 6% above the RPI for the foreseeable future. They are also committed to environmental improvements and in the last Budget they slashed duties on LPG by 29%. The cost differential between petrol/diesel and LPG is therefore set to increase considerably over the next few years. The savings illustrated above will be changed at each Budget to reflect the increased savings that motorists could make.

The prices used in the above illustration are 80p per litre for petrol and 35p per litre for Autogas.
