Get the car serviced regularly (according to the manufacturer’s schedule) to maintain engine efficiency.
Make sure you use the right specification of engine oil.
Check tyre pressures regularly and before long journeys; under-inflated tyres create more rolling resistance use more fuel (check the handbook and increase pressures for heavier loads as recommended).
Before you go
Extra weight means extra fuel so take out anything you don’t need on the journey before you set off.
Roof-racks and roof boxes add wind resistance and increase fuel consumption – if you don’t need it, take it off.
Try to avoid making short trips, as fuel consumption for the fist few miles can be far higher than normal whilst your engine warms up. Combine smaller trips into one if possible.
On the road
Drive smoothly and accelerate and decelerate gently. Read the road ahead, anticipate and adjust your speed in good time to avoid unnecessary harsh braking.
If you can keep the car moving at all time this is great for your fuel economy as stopping then starting again uses more fuel than rolling
Change up earlier – try shifting gear at an engine speed of around 2,000 rpm in a diesel car or 2,500 rpm in a petrol car.
Using air conditioning at low speeds can increase fuel consumption, but at higher speeds the effects are less noticeable.
Turn off your heated rear windscreen, demister blowers and headlights when you no longer need them as electrical loads increase fuel consumption.
Stick to speed limits; the faster you drive, the greater your fuel consumption. Driving at 80mph uses up to 25% more fuel than at 70mph which uses 9% more fuel than at 60mph and up to 15% more than 50mph.
If you get stuck in a queue and it looks like you could be waiting for over three minutes, turn your engine off to avoid wasting fuel.
