shakari Posted March 13, 2013 Report Share Posted March 13, 2013 You can say that about any modern car though. I've gotta say I never had a moments trouble with either of the conversions I had on my Range Rovers but they were good quality kits and they were fitted by professionals.

al4x Posted March 13, 2013 Report Share Posted March 13, 2013 It may be the larger engines are better with it, I had 8 factory fitted vehicles and they ran to 100K ok if you accepted you would have the management light on all the time and ignored it, and just replaced sensors and egr valves when they affected running, after 100k it was engine re build time thats not on the occasional one but every one ok they were all the same make but still. Fuel use they were more expensive to run than diesels but we gained congestion charge exmption so they saved £7 a day at the start and £9 by the time the last went by the end we ran the lot on petrol as it was cheaper and they didn't keep breaking down. The fundamental is though a diesel will be cheaper to run and less risk but LPG lets you play at owning a large engined petrol and afford to run it, bearing in mind most won't do the mileage my vehicles do they work but you need to make an educated gamble.

Thank Alex... Just seems like a way to get a big 4x4 with all the bells and whistles that goes like stink for nthe same running costs as an audi A4 diesel! slim, the thing most likely to leave you with a 15mpg beast is the system going tits up and costing a fortune to fix, Yeahh but if I get one that hasn't been modified and then get the conversion done myself I get 2 years warranty/peace of mind Quote Link to comment Share on other sites More sharing options...
al4x Posted March 13, 2013 Report Share Posted March 13, 2013 thats the bit you have to weigh up paying £1500 or so up front plus the cost of fuel versus spending it on petrol alone, compared to a diesel it will be more expensive and the residuals poorer it just depends what age the vehicle is you buy. Also with the large engines factor in that your range may only be 150-200 miles on gas so you will end up running on petrol a certain amount as well as at startup. A new conversion to me makes more reliable sense than a pre converted one if you really have to do it, Quote Link to comment Share on other sites More sharing options...

al4x Posted March 13, 2013 Report Share Posted March 13, 2013 depends what tank you get but it comes down to practicality ours used to fit the spare wheel well and take about 12 gallons from memory, but you can get different alternatives depending on vehicle and how much load space you are willing to give up and you can run them out as you then just switch to petrol.

Vipa Posted March 13, 2013 Author Report Share Posted March 13, 2013 Oh Har Har So does the spare just get sited somewhere else, i.e. in the luggage compartment? Quote Link to comment Share on other sites More sharing options...
al4x Posted March 13, 2013 Report Share Posted March 13, 2013 (edited) In our case yes, but it depends a lot on if you have an underslung spare or whether you are prepared to have a tank in the boot or in many cases whther you want a can of tyre foam instead of a spare. There are other options out there just depending what vehicle you are looking at. http://www.tinleytech.co.uk/sizes.html Edited March 13, 2013 by al4x Quote Link to comment Share on other sites More sharing options...
Vipa Posted March 13, 2013 Author Report Share Posted March 13, 2013 Cheers Alex... either a 4.7, 5.7 or 6.1SRT Jeep Grand Cherokee.. probably the 5.7 overland flavour Quote Link to comment Share on other sites More sharing options...
al4x Posted March 13, 2013 Report Share Posted March 13, 2013 I think you'd find a spare wheel one would be too small and might need to consider a big tank in the boot to make it worthwhile, otherwise you'd just about be able to make it home from filling it up before running out Quote Link to comment Share on other sites More sharing options...
HDAV Posted March 13, 2013 Report Share Posted March 13, 2013 Mates Astra car used to do 300 ish miles to a tank of gas (depends on outside temp as to how much you can fit in ! ) only used a very small amount of petrol on start up. Not sure how the HEMI works on LPG though. You can run LPG on Carbs but some other considerations. Quote Link to comment Share on other sites More sharing options...
Jambutty Posted January 31, 2014 Report Share Posted January 31, 2014 Agree totally it is down to paying the price for a competent installer - we did a V8 XC90, and after the installer realised he should have put a bypass in to stop the fuel pump trying (and failing) to pump petrol in as well as gas... well, he apologised profusely, free first service, and whole shebang was sweet as a nut after that. Honestly did not see much drop in power, but would kick over to petrol when flooring it in outside lane at - errr - "70 mph". I would be interested in any recent experience of Jeeps with LPG; thinking of one for towing horsebox, as well as 20-mile return journey to work. I know the servicing costs are high, but am more concerned about all the horror stories about burnt-out valves etc (I only put about 20K on the Volvo before I sold it).

four-wheel-drive Posted February 1, 2014 Report Share Posted February 1, 2014 For what it is worth I sold my 4ltr Jeep running on LPG and missed it so much that got it back again as the guy was not using it much the only thing that I would say is have it fitted by a proper installer and get a top of the range kit and you should be ok.

Fib new Posted February 1, 2014 Report Share Posted February 1, 2014 I live in the Netherlands. Over here there are a lot of cars running on lpg with no problems at all. Main thing is it has to be installed by a person who knows what he's doing -so a professional is the way to go! Had a range rover on lpg, ran it for 90.000 miles before I sold it on. No noticeable powerloss, little less miles to the gallon -but still a lot cheaper than running op petrol. Whatever people tell you about the DANGER, it's certainly no more dangerous than a car running on petrol if it's a certified lpg tank. Remember that a tank full of petrol is also a very explosive thing as well... If you want a bit more safety go diesel. Over here almost every petrol station has lpg, so it's not a difficult choice when you do a lot of miles -only downside on driving on petrol over here is the higher road tax...

lampro Posted February 3, 2014 Report Share Posted February 3, 2014 I have a disco 2 4.0ltr V8 running on a zavoli multipoint lpg conversion, it has 2 underslung belly tanks filling up too 80lts of gas with a 15 ltr petrol tank for start ups, ive had the car for 2 years now 63p per ltr gets me approx. 260 miles. Lpg furom tells you where all the garages are that supply, if you do your home work it costs pence to maintain, £4 for a new filter every 2000 miles i20 injector cleaner every 4 months for £15 as gas is very clean on the outside it gunks up the injectors well on the inside I have an annual service just too be safe and it costs me £60 . I have had no performace issues with power out put if your planning a long journey just look on the internet too find out where the garages are also bulk fill suppliers fuel you up like calor gas flow gas, touch wood I have never ran out whilst about. The only thing you carnt do is use the tunnel to france but you don't pay the congestion charge in London as its a green fuel. Quote Link to comment Share on other sites More sharing options...

Fisheruk Posted February 3, 2014 Report Share Posted February 3, 2014 Be careful with Grand Cherokee if you do a lot of off road or towing. I had gearbox and front axle problems after 80000 miles. I asked my local garage what the problem was. The reply I got was “them inguns make their gears out of wood”. Quote Link to comment Share on other sites More sharing options...
Fisherman Mike Posted February 3, 2014 Report Share Posted February 3, 2014 I'm not an expert by any means but I tend to look at things simplistically.. Is not a petrol car designed to run on petrol. ? Is not a diesel car designed to run on diesel ? is not an electric car designed to run on electric ? Is there a car designed to run on Gas.? If you want to run on gas get a hot Air Balloon Quote Link to comment Share on other sites More sharing options...

If you want to run on gas get a hot Air Balloon If you discount the engine built by the Chinese from wood and powered with coal dust. the internal combustion engine is a GAS engine. So in reality the modern petrol engine is a gas engine converted to run on petrol. Herr Benz invented the carburetor and thus allowed the stationary gas engine to be mobilised. webber Quote Link to comment Share on other sites More sharing options...

I think that you will find that most of the later model Grand Cherokees Diesels have Merc engines and gearboxes and buying a car/truck is luck in the end if you get a good one you can buy a new one of any make and brake down a mile down the road. They do say that the Jeep six cylinder 4 ltr petrol engine is one of the best that you can get for converting to run on LPG.

al4x Posted February 7, 2014 Report Share Posted February 7, 2014 Are you qualified or are they iffy conversions? Personally having run a few I hate LPG but we did run vans hard and had nothing but sensor problems and engine re builds due to running on it.

Blacksheep Posted February 7, 2014 Report Share Posted February 7, 2014 There is no law or legal requirement that says you have to be qualified or have them inspected , any competant mechanic can install them you just need to buy a copy of COP11 which is the current install regulations and you only need an inspection if you want to go on the UKLPG register (which is corrupt as **** anyway) How long ago did you run LPG ? they have come on a huge amount in technology in the last 3 years or so Quote Link to comment Share on other sites More sharing options...
