What is Autogas?

Liquefied petroleum gas (also called LPG, LP Gas, or Autogas) is a natural fuel consisting mainly of propane and butane. LPG is manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground.

When LPG is used to fuel internal combustion engines, it is often referred to as Autogas. It has been used since the 1940s as an alternative fuel for spark ignition engines. More recently, it has also been used in diesel engines. Its advantage is that it is non-toxic, non-corrosive and free of tetra-ethyl lead or any additives. It burns more cleanly than petrol or diesel and it is especially free of the particulates from the latter.

Most cars and other vehicles can run on LPG Autogas as an alternative to petrol or diesel. In order to run your car on LPG the installation of a conversion kit is required. The conversion kit itself will not make any major changes to the general appearance of the vehicle, nor will the engine's performance suffer any noticeable loss of power.

Why it is reasonable to convert your engine to Autogas

Environmental reasons

One of the many advantages of Autogas is its benefit on the environment. A car running on LPG emits about 20% less CO2 than a petrol car and substantially less nitrogen oxides (NOx) than a diesel car. In addition LPG engines run a lot quieter than diesel engines.

Financial benefits

The UK government encourages the use of Autogas by keeping fuel duty low. A litre of Autogas currently costs around half of the price of a litre of petrol or diesel. This means by running your car on LPG you can basically cut your fuel costs in half. Also, as low emission vehicles, LPG converted cars are exempted from having to pay the London congestion charge.

Technical reasons

Autogas burns much cleaner than petrol or diesel. Due to the absence of acids and carbon deposits the life of the engine is extended, helping you to keep the value of your vehicle up. Should you decide to sell your car you are more likely to find a buyer, as more and more people are becoming aware of the savings they can make by running a car on Autogas.
