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: LPG • 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) Bio-fuels • 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.
