Up to two million motorists across England have been eligible to apply for grants to help with the cost of converting their cars to run on liquefied petroleum gas (LPG).
LPG is much cheaper than petrol - it's around 37p per litre instead of 72p per litre for petrol.
It is also a much cleaner fuel. Vehicles running on LPG emit lower levels of harmful pollutants than those running on petrol and diesel.
LPG, sometimes sold as Autogas' is available at many service stations in Yorkshire.
The grants are available through the Government-funded TransportAction PowerShift programme.
Each grant covers up to 60 per cent of the cost of conversion - or of the extra cost of purchasing a new, clean fuel vehicle. Conversion typically costs between £1,300 and £1,800 - but you'll get up to 60 per cent back.
As well as the money you'll save on converting your car, you'll also save on your running costs, week in and week out.
On average, an LPG car will travel 180 miles on £10 of fuel whereas a petrol car will travel just 106 miles.
To be eligible for a grant, a vehicle model must appear on the PowerShift Register, TransportAction's approved list of vehicles and conversions. This means that the conversion (or new vehicle) has been approved as safe, built to suitable quality standards and that it produces less pollution from its exhaust pipe.
The PowerShift Register is searchable on the internet at: www.transportaction.org.uk
