According to Autogas, its LPG conversion kit allows a conventional combustion engine to produce 80 per cent less NO2 than diesel, and several times less than unleaded.
Lower CO2 emissions are also a bonus, with a 15 per cent reduction claimed. Elsewhere in Europe, LPG is already a popular solution to rising fuel prices and environmental concerns. Up until , the UK offered similar grants, but the Government dropped it and got behind electric vehicles and hybrids instead. LPG still makes the most financial sense in the UK for private owners who are determined to keep their gas guzzlers, and fleet buyers doing stratospheric mileage. Certainly for companies running multiple vehicles, the saving would be significant.
With the current financial incentive for EVs about to end, perhaps there is a case for it to be applied to LPG cars again. Certainly, if reducing NO2 emissions is a priority, this could be a way of helping achieve that. Would you convert your car to LPG? Let us know in the comments below Skip to Content Skip to Footer.

LPG is a highly efficient fuel, so you get a good return on every unit of energy. Replacing a standard LPG boiler with a highly efficient modern condensing boiler is a relatively straightforward job. Running costs on gas — we still use a little petrol per tank — have been 12p a mile, compared with 17p if running purely on petrol.
