Pentagon Fuel Calculator
The fuel consumption information on this calculator is from the Combined MPG figures and they have been obtained in good faith from CAP data. Whilst every effort has been taken to ensure the accuracy of the above information, some inaccuracies may occur. Data for older models may vary slightly so you should always check details with the dealer prior to purchase.
The case for driving a more fuel efficient Vauxhall...
The average motorist covers around 12,000 miles every year. If a driver moved from a diesel car doing around 35 miles per gallon to the Corsa 1.3 CDTi returning 62.8 miles per gallon, the fuel saving alone would be a £71 a month, or a massive £852 a year. Plus you'd only have to pay £35 road tax, saving even more! 
Figures based on paying £1.25 a litre of diesel and on the combined miles per gallon cycle.
Ten Top Tips For More Efficient Driving
The way you drive is not only important for your pocket, it also matters to the environment.The European Petroleum Industry and the European Commission has put together these efficient driving tips to help everyone reduce fuel consumption. We hope you will find these tips helpful.
1. Keep your car well serviced and check the oil level regularly.
Correctly maintained cars can operate more efficiently and help reduce CO2 emissions.
2. Check your tyre pressure every month.
Under-inflated tyres can increase fuel consumption by up to 4%*.
3. Remove unnecessary weight from your boot or back seats.
The heavier the car, the harder the engine has to work and the more fuel it consumes.
4. Close your windows, especially at higher speeds, and remove empty roof racks.
This will reduce wind resistance and can lower your fuel consumption and CO2 emissions by up to 10%**.
5. Use air conditioning only when necessary.
Unnecessary use increases fuel consumption and CO2 emissions by up to 5%**.
6. Start driving soon after starting the engine and turn off the engine when stationary for more than one minute.
Modern engines enable you to just get in and go, thus reducing fuel consumption.
7. Drive at reasonable speeds and above all, drive smoothly.
Every time you accelerate or brake suddenly, your engine uses more fuel and produces more CO2.
8. When accelerating, change up gears as early as possible.
Higher gears are more economical in terms of fuel consumption**
9. Try to anticipate traffic flow.
Look at the traffic as far ahead as possible in order to avoid unnecessary stopping and starting within the flow of traffic.
10. Consider car sharing for work or leisure.
You will help reduce congestion and fuel consumption.
