    Honda Bulletin No SK-03-005-01-UK dated 08-09-10

    Further to recent contacts from the Dealer Network regarding the possibility of converting Honda vehicles to run on alternative fuels, Honda (UK) would like to take this opportunity to clarify the facts concerning these fuel sources.

    Honda has invested heavily in Research and Development activities to refine both our petrol and diesel engines to suit the current fuel infrastructure. Long-term plans include the increased usage of hybrid technology, as seen in the current Civic Hybrid and the forthcoming Insight, which can offer big gains in efficiency and environmental benefits over conventionally-powered vehicles. However alternative fuels such as LPG and bio-fuels have grown in popularity mainly due to:

    • Government funding.
    • Lower cost of fuel.
    • Possible Company car tax benefits due to a reduction in Emissions levels.

    More information relevant to the particular type of alternative fuel is given below:
    • Tests have proven that LPG conversions may cause engine and/or fuel injection component failure.
    Component failure associated to an LPG conversion will not be covered by the Honda warranty.
    • The distribution of LPG fuel within the United Kingdom is still quite poor. Currently just 13% of service stations have it.
    • To-date cars fitted with LPG have suffered from higher depreciation than normal (mainly because of the above issues) .
    • The current low fuel tax on LPG fuel (which makes the fuel cheap) is not guaranteed in the future.
    • There is a small but inevitable loss of power / fuel efficiency with engines running on LPG since the fuel contains less heat energy than either petrol or diesel.
    • Dual fuel vehicles suffer from some loss of boot / storage space as a result of the secondary fuel tank
    • Vehicles with LPG conversions are barred from travelling to the continent through the Channel Tunnel because of safety concerns (the gas is heavier than air and would collect at the base of the tunnel if a leak was to occur)

    • As with LPG, tests have proven that running engines on bio-fuels may cause engine and/or fuel injection component failure. Component failure associated to a running the vehicle on bio-fuels that do not meet the current "EN" standards will not be covered by the Honda warranty.
    • Only fuels meeting the current EN standards can be used in Honda vehicles, this information is also contained within the owners manual. These fuels contain a maximum of 10% bio-fuel content and this is the maximum amount permitted to be used in Honda vehicles. These standards are EN590:2004 for diesel fuel, EN228:2004 for 95 Octane unleaded fuel and BS7800:2004 for 97 Octane unleaded fuel.
    • Fuels that do not meet these standards should not be used under any circumstances, these include, but are not limited to, E85 unleaded fuel and B30 diesel fuel. (available from certain supermarket filling stations)

    Customer Advice
    Honda (UK) recommend that appropriate advice is given to customers who propose to convert, modify or use non-approved fuels in Honda vehicles, to the effect that the Honda European Warranty will be affected by any unauthorised modification. Any damage that results from, and is traceable to, the modification will not be covered by warranty. Parts not related to the modification will still be covered by the full manufacturers warranty.

    HMMMMM had my 7th Generation Accord converted to run on LPG last December and covered 15000 miles so far with no issues, no noticeable loss of power or economy. Car is 2006 so not covered by any Honda warranty and feel smug every time I fill up and pay my £15.00 for a full tank. Cost at the moment is 51.7p per ltr. currently covering 150 mile round trip every day to and from work and averaging 30mpg, Plenty of gas filling points on my journey and never had issues finding a refilling place when going on a different journey. heard lots of horror stories but if you have a good system fitted and a valve saver system I have found the benefits and running costs far outweigh any disadvantages. its not for everyone, I appreciate that but just letting people know of my positive experience. Pre LPG gas installation fuel bill was over £600 per month, I have got that down to less than £300. the system paid for itself in four months.

    Yay fellow LPG dude !!!! :Friends::Smile:

    I've fitted lots and lots of LPG systems to Hondas and specifically 7th Generation Honda Accords. All running without any issues whatsoever. I don't think I've seen an engine problem on Honda that has been caused by LPG yet.

    If you ever need any advice LPG Scotty just tag me (@SpeedyGee)

    BTW £15 fillup .. that's quite a small tank then ??

    More applicable to new owners back then considering LPG on cars within warranty but it still doesn't take away some fact which are universal.

    Hi SpeedyGee
    I undertook a lot of research into LPG before getting conversion fitted and heard all of the horror stories about premature valve wear, more frequent spark plug changes etc... but as I said if you have a good valve saver system fitted and keep it topped up then you should not have any problems. I was concerned about buying a 2.4 Honda owing to the amount of miles I cover but with this conversion making no noticeable difference to performance and minimal effect on consumption I am really glad I took the plunge. I wrote my diesel merc CLC 220 off in November and needed to buy a reliable car that I could use everyday and would not be affected by high mileage so I conducted a basic non scientific impromptu survey carried out over a month, noting makes of cars on low loaders or on the hard shoulder of the motorway. I never saw one Honda but every other make was there. that is what made me decide on Honda, then I had to choose which model, I need to cover a lot of miles and arrive fresh so the Jazz was out as being to small I wanted a bit of oomph available when needed so it was the legend , accord or Civic, this Accord came up for sale with very low mileage and full Honda service history in perfect showroom condition, yes it was a little overpriced but I managed to negotiate £1000 off. I asked the LPG fitters to put the largest doughnut tank in they could fit in the spare wheel well and brought myself a puncture gunk kit (I have one in my partners Mini cooper S so was not concerned about the lack of spare wheel) I think it holds around 35 - 40 ltrs which is enough for me to go to work and back and any long distances I need to do I just use an LPG app on my phone to find filling stations.

    Thanks Ichiban I appreciate it is an old thread posted in 2010 but was scrolling round the site and just thought I would share my positive experience of LPG in case another member was on the fence in deciding to go for a conversion or not having heard all of the horror stories. just balancing the views.:help::Hey:
