Eco-Driving + Fuel consumption calculator
3 Easy Eco-driving tips
Where it is safe and legal to do so,
- Maintain a steady speed, using the highest gear possible to keep your engine working at its most efficient.
- Shift into a higher gear as soon as possible;between 2000rpm and 2500rpm.
- Decelerate smoothly by taking your foot off the accelerator, leaving the car in gear. Modern engines don't use fuel under these conditions.
Eco-driving Benefits
- Save money on fuel - Eco-Driving fuel costsare typically10% lower.
- Reduce vehicle maintenance costs.
- Reduce local air pollution.
- Reduce your impact on Climate Change.
If your vehicle is not equipped with a revcounter, use your speed as a guide to gearchanging:
- 1st gear: to set off
- 2nd gear: up to 15 mph
- 3rd gear: 15 - 25 mph
- 4th gear: 25 - 30 mph
- 5th gear: 30 mph+

How To Calculate Your Fuel Consumption
You won’t know if your new driving style and skills are working unless you know the average miles per gallon (mpg) of your car. Some cars have on-board computers, but they are not always accurate.
When you fill up your car, fill the tank to the top and simply make a note of:
- Your mileage since the last fill
- The number of litres of fuel you put in
- The cost per litre of fuel
Then simply use the fuel consumption calculator below:
Or, to work it out yourself:
- Fill your tank to the top
- Zero the trip counter
- When you next fill up, note the mileage driven
- Fill the tank again and note the number of litres put in
- Divide the number of miles driven by the amount of fuel used in litres (miles per litre)
- To convert the figure to miles per gallon multiply it by 4.544
Example
Frank does stages one and two above. His trip meter reads 160.1 miles when he next fills up. It takes 22.3 litres to fill his tank. Frank works out that his fuel consumption has been:
160.1 divided by 22.3 = 7.179 miles per litre.
This is 7.179 x 4.544 = 32.62 miles per gallon.
