LPG fuel conversions for fuel efficient cars and reduced CO2

LPG and CNG Fuel

Liquid Petroleum Gas (LPG) has proved fairly popular due to Government tax incentives making the fuel relatively cheap to buy. The Government has started to reduce the tax benefit between LPG and conventional fuels like petrol and diesel and will continue to do so in the future. Cars using LPG tend to be dual-fuel and can run on both petrol and or LPG. Tailpipe emissions for LPG vehicles tend to be cleaner than petrol vehicles, and diesel, having less CO2 and reduced pollution.

Compressed Natural Gas (CNG) offers even lower CO2 tailpipe emissions , with very low particulate emissions. CNG cars can also run on bio methane, creating even lower CO2 emissions.

CNG and LPG vehicles are generally converted from petrol fuelled cars, either by the original manufacturer or by a specialist LPG converter. Some car manufacturers now offer options for cars, which have been designed to run on gas fuels.


Produced from oil of crops such as oilseed rape, sunflowers and soybeans, and from waste cooking oils Biofuels are being introduced gradually. They are sold in combinations of up to 5% with petrol or diesel mix. They are not completely carbon neutral as energy is used growing them but they offer significant CO2 savings over petrol and diesel fuels. They are compatible with most vehicles and can now be found at a number of pumping stations. Check with the vehicle manufacturer to ensure they can be used.

Biodiesel is widely available and more widespread than bioethanol and higher blends of biodiesel can also be used in various vehicles. Some cars, known as flexible fuel vehicles can run on a mix of up to 85% bioethanol & 15% petrol, this is known as E85.
