Why not Autogas?

Why not Autogas?

With a better environmental record, LPG Autogas is by far the most widely available environmentally friendly alternative fuel.

Most petrol engines can be converted and there are currently around 21 million vehicles worldwide with over 10 million in Europe and over 170.000 in the UK running on LPG. They are producing less harmful emissions than those using petrol or diesel, whilst making significant savings at the pumps.

In the UK, LPG costs around 50 pence per litre cheaper than petrol and diesel. Although the miles per gallon when running on LPG is usually around 20% less than petrol, because it is so much cheaper, significant savings in fuel costs can be made – see how much money you can save!

Environmental effects 

A stated by Drive LPG, based on independent testing of nearly 9,000 cars from the EU that were manufactured recently and that have state-of-the-art pollution controls, those that run on LPG produce 11% less CO2 in operation and about 15% less from ‘well to wheel’, i.e. over the entire fuel supply chain than identical cars run on petrol.

In 2004 The Department of Health statistics show that particulates are responsible for thousands of premature deaths and thousands of illnesses. NOx emissions are also a major element of low level ozone, which causes smog and can worsen existing asthma conditions.

As reported by Drive LPG, extensive independent tests showed one diesel vehicle emits 120 times the amount of fine particles as the equivalent LPG vehicle and it takes 20 LPG vehicles to emit the same amount of NOx as one diesel vehicle.

Furthermore, Autogas will quickly evaporate in the event of a fuel spill, unlike petrol and diesel so there is no risk of ground or water contamination.

Autogas is considered as the greenest and cleanest alternative fuel. Indeed, being a low carbon content fuel which reduces your carbon footprint, producing harmful emissions that impact on air quality and reducing noise pollution.

LPG cars provide 11% CO2 benefits. In 2013 the Atlantic Consulting conducted a research comparing results for 1251 models of bi-fuel vehicles, revealing there was an average 11% CO2 tailpipe benefit when running on LPG compared to the identical car running on petrol. To demonstrate log ins considerably lower, it is essential to remember diesel is 29.2% higher than LPG, while petrol is 26.8% higher.


Financial effects

The forecourt price of Autogas is approximately half that of petrol and diesel. Whilst the miles per gallon when running on LPG is usually around 20% less than petrol, significant cost savings can be made.

The price of LPG at the pumps benefits from lower fuel duty than petrol or diesel. In his 2013 Autumn Statement the Chancellor of the Exchequer announced a 10 year commitment on fuel duty for LPG. This gives consumers the reassurance that the government continues to support LPG and fuel duty will not be suddenly removed.

As has been the case since 2003, the commitment is an undertaking that the fuel duty variation between petrol and diesel will not reduce by more than 1p per litre per year. In practice this has rarely been implemented and UKLPG will continue to work with the government to ensure that the price differential at the pumps continues to provide the annual savings for consumers.


Some Autogas vehicles are eligible for the Alternative Fuel car reduced rate. Find out if your vehicle is eligible by visiting the DVLA web site by clicking here. To register your vehicle at the DVLA as an Alternative Fuel Car you will need to submit to the DVLA an original Registration Receipt on the headed notepaper of the installer.

Discounts on parking schemes – if you drive a LPG fuelled vehicle some local authorities offer a discount on resident and business parking permits, visit your local authority web site to find out more.


In the light of what has been reported, there is no doubt that in the future LPG will play a major role to improving the environment and also the health and safety of the worldwide population.  For a full report on the matter we do recommend Autogas in Europe, The Sustainable Alternative, made by AEGLP.
