Savings explained
LPG (Liquid petroleum gas) is a mix of Butane and Propane gases, stored under pressure to keep them liquid. When the liquid is fed into the engine it is converted to a gas that is then burnt. This reaction produces less carbon dioxide per unit energy compared to petrol engines.
Click here for studies that have determined the emissions for LPG and unleaded petrol as:
- LPG: 1.863 kgCO2/L
- ULP: 2.893 kgCO2/L
The true financial savings come because of the relative costs of LPG to petrol or diesel. Even taking into account that petrol and diesel produce more energy per litre (see here), LPG is more efficient in terms of pounds per kilometre. Use the calculator below to find out just how much more efficient it is.
