With petrol and diesel prices rising, motorists are looking for more ways to save money on fuel.
Liquefied Petroleum Gas (LPG) – or Autogas – is an alternative fuel which costs about half the price of petrol and has lower CO2 emissions, but lower fuel economy.
We revealed if switching to LPG could save you money – but what’s it like to own an LPG-powered car? Have you converted your car to run on LPG?
We took five popular UK cars to see how much they’d save by converting to LPG – and the Audi A4 came out on top with an annual saving of £794 per year.
With an average engine conversion fee of £1,600, it can take around three years before you notice a saving in fuel costs.
Most engines can be converted to run on LPG, and some cars will run on LPG from new – including the Proton ecoLogic Gen-2.
Owners of LPG cars can generally expect to see a 20 per cent decrease in fuel economy (MPG) however, when compared to petrol and diesel cars.
The LPG trade association, UKLPG, claims long-term savings from lower fuel costs make up for this.
There are more ways to save money on fuel, including reverse parking, changing gear at the correct time and inflating your tyres to the correct pressure.
Would you ever consider converting your car to run on LPG to save money?
What are your experiences with LPG? Is it as reliable as petrol and diesel?

I have a Range Rover (converted) and a Volvo (factory fitted) and travel extensively. Not only am I helping the environment by limiting the amount of noxious gases that I output into the environment (unlike my diesel and petrol cousins) but also save cash each time I fill up. Benefits are reducing pollution into the environment and saving money. Draw backs are that you need to re-fuel every 250 miles or so. I have had no problems finding LPG in the UK, France or Belgium, all it needs is a little forward planning! Not sure why LPG vehicles can’t use Eurotunnel but caravans with LPG bottles can. Let’s hope that the government don’t spoil it with higher taxes in the future like they did when people realised that diesel was a cheaper alternative to petrol (only a few years ago)!!

I’d like to do a research project on this and am looking for some LPG vehicle owners who are based in London to take part. Is there anybody out there who is interested – you will be paid to share your thoughts and ideas on the future of it.
Thanks in advance

Hi!
In Poland many people use LPG powered cars. Most of them convert cheap or older cars (escort price range) or american (5.7 or 7.2 ccm engines!). If you do huge mileage a year or your car takes a lot of petrol it really pays up. But if you convert a brand new car you may loose guaranty! Consumption of LPG is 15-20% higher than petrol. One more thing! The simpler engine the easier and cheaper conversion.

Yes our cars run on LPG conversions.
LPG, Propane, Autogas are all the same fuel, the stuff thats in red gas bottles and deodourant aerosols……So its commonly used and commonly exported from the UK.
Commonly the saving over 24 000 miles will pay for the entire system….
Every modern car and van is capable of 240 000 miles. So one could easily see a return of £20 000 over this period.
The higher your mileage the greater the return.
The bottom line is without putting miles on your car the reductions cannot be achieved.
The easiest way of seeing a Autogas conversion is as an option extra like electric windows, statnav/stereo. Absorb the cost in with your vehicle purchase cost.
Most petrol models, including a few GDI/FSi/Direct injection, of cars and light vans can be LPG converted.
Some LPG models avoid the London Congestion Charge zone payments. An annual saving of £1650 alone. These models include Citroen & Ford vans and a number of cars – Passat 1.8T is one of them….See the list of Congestion Charge exempt vehicles :-

You can run on Autogas with very little effort and make a big difference to your pocket and the environment.
Its easy. Look into it today

With all these new road tax bands where does that leave lpg fulled cars. I have a ML320 running on LPG and my MOT cert states zero emissions so my car should be in band A. But all it says is that vehicles that run on allterunative fuel will get a £20 discount, is this correct? or is my car tax free? My tax renewal is in June.

I have run a Nissan Patrol on LPG for 2 yrs now with no problems. In fact I have just bought another one. This car does about 40,000 miles a year and the saving over petrol or diesel is significant. I am so impressed that my Daimler, that used to be my daily driver and has now been garaged for 2 yrs because of running costs, has just been pulled from storage to convert to LPG and I will not only have the luxury of using it as my daily driver again but I can do so in the knowledge that I am causing less pollution with my “gas guzzler” than most folk do with a Euro style shopping trolley
.
I would say that there should be more filling stations but then again if there where LPG would become more popular and our esteemed Prime Mentalist would find a way to tax it heavy———-Just like they did with diesel! (remember when diesel was cheaper than petrol?)
No! keep it to the few who really care enough to find out about it and convert. Not to the “pocket Greenies” who spout about saving our planet with schemes that end up producing more harm than good.—— Let us recall some of the hard earned tax dollars that the gov. has stolen from us and do some good at the same time.
Just for interest. One of my working vehicles is diesel; it does more MPG than the Patrols but costs more to run???????. Unfortunately, there is not a petrol alternative available in this country but we are about to start producing our own Bio diesel for it so again recalling tax dollars at the same time as reducing our carbon emissions. I would be glad to help with any research project but keep it quiet eh! .

Hi Pete,
you sound like a man of my own heart… I run a V8 4.5 litre BMW 7 series on a school caretakers wages… Mine is the best in the carpark, grin… I have travelled towing my Bailey ranger 5 berth caravan from Hull to Glascow with a 60 litre tank, it cost me £27.47 last year… and not dawdling either, I bought the car converted but I had previously had my Ford scorpio converted by Autogas at a cost of 2k I think it well paid for itself easily within 2 years on a 2.3 engine.
I am the opinion that the bigger the engine the better it works out, it certainly improves the performance and I am highly delighted with the results.
One up for us heh…
