Car news website Auto Express recently held a survey of 1500 car owners, and found that more than a quarter of drivers would consider converting their car to liquefied petroleum gas (LPG).There are now 1,400 LPG filling stations across the UK, offering a much cheaper alternative fuel to the conventional petrol and diesel. LPG is roughly half the price of petrol and prolongs the life of your engine. Savings can be made on LPG powered vehicles not only in a monetary value but also environmentally, due to LPG’s low carbon content and quieter running noise. If you can prove to the DVLA that a conversion has taken place on your vehicle and your emission rate has fallen, you may qualify for a £10 reduction on your car tax.Although the major car manufacturers recognize this market, their LPG car production still remains minimal for a niche market.Despite the benefits, converting vehicles from petrol to LPG should be carefully considered as costly conversions (£1200 - £1500) will only ever ‘pay off’ if the driver’s mileage or length of ownership outweighs the original outlay. Once governments accept the betterment of this natural gas by-product, LPG vehicle manufacturing will increase and the marketing momentum will build, quelling fears that some consumers have over the safety, performance and insurance hikes.Original conversions weren’t without their faults, sometimes poorly / dangerously fitted and so bulky that they would take up valuable boot space. Due to significant technological advances, an LPG conversion can now be done safely within a day. Today kits are tailor made to fit into an empty wheel well or in the case of 4x4 vehicles – under the chassis.As the EU begins to pressure European governments on meeting ambitious climate and energy targets (before 2020), it would seem LPG fuel is an obvious start. Conversions to council vehicle fleets such as buses, waste disposal, grounds maintenance and emergency would set a precedent on how to reduce costs and be kinder to the environment.It would seem the demand is there to increase the use of LPG in our day to day lives but the supply still has its shortcomings in investment and confidence.
