my ls430 paid for itself in about 18000 miles. for the further 62,000 miles I did in it, it saved about 2.5k a year on go-juice.

On a motorway run it was doing roughly the equivalent of 50+mpg.

Smaller more economic cars take longer to pay back.
A reasonable comment.

Could work it out on the figures you provided but might as well ask - how much did you pay for the conversion?

I honestly haven't worked out how much you payed for the conversion, but at my price for conversion for your car (£1395) you would make the payback threshold (in terms of simple fuel savings, not taking into account the value added to the car) in 6 and a half months given you save £2500 per year.

We agree about the payback period being a bit longer for small economical cars, but then again small cars with 4 cylinder engines don't cost as much to convert (I mentioned £1000 for the Hyundai Accent). As we move into cars like yours, big cars with V6's, V8's, 4wds, etc. the payback period is shorter than in my Hyundai example - I didn't use a great example quoting figures based on my son's Hyundai, but my post related to a thread that was about another Hyundai. Elsewhere on this forum I have posted pics of a Vauxhall Monaro 5.7 V8 I converted last September, and have recently posted again on that thread because I have just converted another Monaro. The owner of the last Monaro converted uses it as a daily driver; He works in London but is Romanian, and he plans to drive to and from home in it a few times a year. I expect his payback period will be very short indeed!

Simon
cost me £1600 for the V8. I kept a spreadsheet of all costs, petrol, LPG servicing etc and used a conservative assumption of 15% loss in MPG.

All this talk of cost savings has got me all excited: so I decided to have a look at where I could actually buy LPG on my 40 mile commute.

Not one single place!

Now I realise why not one single person I know, drives a car running on LPG. Hardly anywhere sells it.

Where do you live/ work? I Drive all over the country for work and a quick tap on an app and in never more than 20 miles from a station?!

Interested to know where you looked up your stations? Fill lpg is about the best/ most accurate ive found.

I do a 50 mile commute and pass 3 lpg stations directly... with 2 more on a divert of less than 1 mile

I'm amazed if no gas provision is available at all.

Update: I missed one. There are more.

I'm seriously considering having a conversion. The only thing stopping me is the fact my car is worth less than the conversion. So I'm torn as to whether to have it done to THIS car, or buy one with it already done. Swings and roundabouts I guess.

I think its a fab idea - only sad I bottled out of having one done a number of years ago.

The idea and use of it is great, its just that after a bit of research on the issue and getting a bit clued up on it, I couldn't find an installer that stood up to some gentle inquiry they all came across as people who didn't fully understand the process and fell apart when I asked questions.

The problem with being in engineering is that I expect the same level of rigor applied to the install as I do in my own job.

If I had the time to do it myself and get it certified I would.

Moral, choose your installer and insist on quality part such as vapouriser and injectors.

As said by others above, there LPG filling stations all over the country, and even www.filllpg.co.uk doesn't list them all.

Thanks for the comments Fanboy. You should have asked me about the process, I do fully understand it, I am very familiar with almost all LPG system components and have developed a bit of a niche for successfully converting the vehicles that other installers find technically challenging - I'm sure I could answer all your questions! But you are correct that there are installers that fall short, many fit components that are less than ideally suited to the vehicle and/or do a poor job of installation.

It can be difficult for customers to decide which installer to use, as installers are generally well practiced at sales talk! When it comes to parts, it can be difficult for a customer to steer through all the advice / mis-advice in order to get a realistic idea of which parts are suitable and to understand why. Personally researching components can also be a minefield for a customer - a bit of reading up on spec sheets etc won't give working practicable knowledge of the components being considered and spec sheets often don't reflect real world capabilities, while most advice will be biased.. A Bosch fuel injection devlopment specialist, whom we would expect to be able to choose suitable components, might also get it incorrect if he only had spec sheets to go on, because some info on spec sheets is hyped and spec sheets don't show reliability info.

In order to make informed choices the customer would also need working knowledge of the particularities of their engine's petrol fuel system in order to select the best LPG ECU to match.. A simple and basic example - I know that if I convert a basic Rover K series engine I will need to select an LPG ECU that can filter the K Series petrol injection system's 'extra injection pulses', many LPG ECU's have this ability but some LPG ECU's are much better at doing this than others and some don't offer this ability at all.. I know which ECUs are good and bad at this. Most people, even mechanics and engineers, would not be aware of the K series extra injection pulses unless they also had experience in the LPG conversion industry... Extra injection pulses are something that most people don't need to know about, probably not even Rover main dealer diagnostics technicians. If someone decided to go it alone, did some research, including asking some pro-installers for advice, managed to select appropriate injectors and reducer, selected an otherwise well featured and respected ECU - they could still be left with an unavoidable misfire on acceleration - All it would take to get it wrong would be not to ask questions, or to ask the wrong people, or not mention the system was specifically going to be fitted to the K series engine. There are many vehicle fuel systems with slightly odd fuel delivery methodologies, the K series only a simple example, so even with the best intentions and preparation it is easily possible for a layman to get it wrong. Besides fitting new LPG systems on vehicles I also sell DIY kits with tech support included - I put thought into advising specific parts for specific vehicles but some DIY customers (that have also received advice from elsewhere or done research of their own) second guess my advice.. and this usually means their install costs at least equally as much (often more) and the system isn't as well suited to the vehicle or as long term reliable as it might have been.

As with any job, thorough working knowledge of the job can only be learned by actually doing the job and those that end up being the best at it are those with the best understanding, experience, developed skills and best intentions. You are probably a better engineer now than when you left engineering school, and I would be a better LPG installer now than someone who (if this were possible) had just left uni with a degree in converting vehicles to LPG...

Now then, folks, here is very good advice.

Couldn't agree more.

Thank you.

I have 4 within 5 miles. I don't know where you live, but you just need to time your visits. I was traveling between Halifax and London - filled up in halifax - couple of miles out my way, then filled up in London again a bit out of my way.

Sainsbury, Morrisons are good candidates, BP and Shell the others

So Sparkylux, would you consider an LPG conversion if you thought you could get it close to you? You could maybe give us the first part of your postcode.. then we'd be able to advise where you could fill with LPG... but you'd probably still somehow convince yourself it wouldn't be a good idea to convert to LPG for some other reason?

The website www.filllpg.co.uk has a map of LPG filling places, but it's list is by no means a complete list... There are a few places within only 10 miles of me that are not listed even on this website!

Granted there are a few areas in the country where LPG is more difficult to get, but only a few!

Not really travelled that far since I had my conversion done last year but I've never had any issues with filling up. I have two LPG stations on my daily commute and two more within a 7 mile radius.

I'm an owner and big supporter of lpg. On my second gas powered car. I'll wade in here and help him out. There are some catches for sure!

On the conversion on my accord and former 5 series tourers:-

  • Lost my spare wheel (slim chance of a flat and mitigated with gunk but not ideal)
  • range is awful as the torodial tank is too small (300 mile max range, on unleaded car does 400)
  • extra maintenance. I know you will say overall it costs less, but still it's additional maintenance to consider, even if just from a time perspective
  • finding it isn't always dead easy. I travel a lot for work and as has been pointed out its easy to get if you detour a little. Often I don't want to do that as I'm late/ tired/ missing my kids bathtime, so I end up using unleaded to extend my range to the next services with lpg
Overall, the only one that really bugs me is the range, but I wasn't prepared to lose boot space so there's little other choice.

It's unfair of you Simon to pretend there are no down sides at all and it's all positive, even though you have a vested interest from a fitters perspective.

There are, clearly, a few things to consider, loss of boot space (mine is huge even with a 90L sausage tank) but I can fit the spare in too.
Extra servicing as mentioned (mine has a leak and whiffs).

However, I now pay 49.9p per litre which has to be one of the cheapest in the country and the garage is on my work commute so convenient. Supermarkets are often good value, or garages that are looking to attract people in like rural ones but not all.
The price can go up as high as the 70's at those Countrywide places. They make it harder to purchase the stuff as you to join the club and need codes to access the pumps. Too much hassle!

From my post on anther LPG thread (edited slightly)...

Synchromesh said:
I run an BMW E46 325i touring on LPG. The things that annoy me, in order of annoyance, are:

-It's got a rubbish range (300 miles)
-It takes longer to fill up (and you can only fill up from one side, so sometimes have to wait longer for a pump)
-That "filler cap of shame"
-Very few petrol stations sell gas so some planning is needed
-The variance in the price of across different stations (I've paid between 52ppl and 74ppl)
-I don't have a spare wheel as the LPG tank is in the wheel well
-I get 23mpg in mixed use (but with little respect to driving economically)

I can see those points and I appreciate that they are will balanced and made fairly.

Some vehicles don't come with a spare wheel these days anyway, but if carrying a spare wheel is important to you, you can always put the spare in the boot when you don't need all the load space? Instant tire repair aerosols will effect a repair for most flats anyway (and modern space-saver spares can also only be considered a temporary repair)?

In your above example, range on petrol is 400 miles, range on LPG 300 miles, so range on LPG is 25% less that range on petrol but, of course, your total range has gone up from 400 miles to 700 miles... That is, it would be if you didn't mind running on petrol.... So this point says as much for LPG as it does against, because you do mind running on petrol - It saves you lots of money, right? And you could have had a bigger tank or small second LPG tank fitted to give better range on LPG than on petrol..

Extra maintenance involves the changing of 2 filters every couple of years which together might cost a tenner if you change them yourself. Compare this 'extra maintenance' on top of usual petrol engine maintenance costs to the extra maintenance that a diesel engine requires over a petrol, then on top of this, factor in the increased likelihood of a diesel engine developing problems with DMF, DPF, EGR, injector problems.

OK, finding LPG isn't always easy if you often drive in unfamiliar areas and sometimes a small detour to fill with LPG is necessary. But I wonder how many people are prepared to make a slight detour to pay only a couple of pence less per litre for petrol or diesel (representing maybe a 1% or 2% lower price than the garage that's much closer). In the case of LPG, we're not talking about driving a few extra miles to save just a couple of pence per litre, we're talking driving a couple of extra miles to save in the region of 50p per litre (representing maybe over a 50% saving)! How far do you reckon diesel / petrol only vehicle owners would go out of their way to buy petrol / diesel at 49.9p per litre? Currently around 1 in 6 petrol stations sell LPG with this number increasing all the time and many other types of fill stations exist too, such as Calor depots.

Oilchange - it's funny you should say the garage near you at 49.9p per litre is one of the cheapest in the country.. What a coincidence, because it's available at 49.9p per litre within 5 miles of me too! Around Birmingham it is available at 39.9p per litre. I have never seen a 'member card activated' pump, the low prices are available to anyone.

None of the points so far mentioned says anything negative about how the vehicle performs on LPG or about reliability, though the leak issue someone mentioned should be a concern - Should get that looked at, it will be something simple and inexpensive to fix!

I recently ran an Alfa GTV V6 on LPG (I bought it already converted).

Pro's:
I could do my daily commute (100 miles roundtrip), no problem. And that's not something that can be said of the regular V6 unless you had a bottomless wallet.
I had a smug smile every time I filled up the car with LPG, paying almost half the cost of petrol.
I was doing my bit for the environment.

Con's:
I got about 15% less mpg compared to petrol.
Very occasionally, when accelerating hard, it would slip out of LPG mode and onto petrol with a sub 1 second hiccup in the power delivery.
I'd worry about having one without the 'Safelube' or whatever it's called system.
I did 'burn' my hand once when the stupid filler spat colder than ice LPG over me.
My boot, already small, became tiny.

I sold the GTV a couple of years ago and, all in all, I'm glad it had an LPG system. I'd have another.

Wow! 39.9p/Litre is really cheap, didn't think it went that low!
