The most important reasons for using LPG fuel
Environmental and pollution issues
LPG is a world-wide, environmentally friendly, fuel and is comparatively clean both from the standpoint of carbon emissions and low hydrocarbons (70% of those of petrol), but equally importantly contains no PM10 toxic pollution/poison (smuts) most often ignored when comparisons are made with diesel engines (it’s the black stuff that you see coming from even the newest diesel vehicle tail pipes).
Internal engine deposits are less for all new, or at least healthy, petrol engines, so engine life is substantially increased due to reduced wear and tear on your engine.
LPG is otherwise a waste by-product
As it is a by-product of oil production it would otherwise be burned off in the refining process and be wasted as an energy source.
The Knock or octane rating
The octane rating for LPG is very high compared to other fuel (LPG ± 110 octane. Regular-grade petrol ± 92 octane and premium-grade petrol ± 95 octane).
LPG is easy to store as a liquid at ± 6 bar. (relatively low pressure and relatively very safe). This makes low cost tank options available, and allows good levels of fuel storage capacity.
Oh, and it’s a lot cheaper too!
And it’s most likely to remain that way for some considerable time as the governments of the world face higher and higher pollution taxes and environmental pressures. Last year hundreds of thousands of vehicles were converted world-wide.
