Make sure you use the correct specification of engine oil.
Check tyre pressures regularly and before long journeys. Under-inflated tyres create more rolling resistance and so use more fuel. Getting tyre pressures right is important for safety too.
Extra weight means extra fuel so if there’s stuff in the boot you don’t need on the journey, take it out.
Roof racks/boxes create extra wind resistance and so increase fuel consumption. If you don’t need it, take it off. If you do need it pack carefully to reduce extra drag.
Easy does it!
Drive smoothly, accelerate gently and read the road ahead to avoid unnecessary braking.
Change up earlier
Change gear as soon as possible without laboring the engine, try changing up at an engine speed of around 2000 rpm in a diesel car or around 2500 rpm in a petrol car.
Cut down on the air con
Air conditioning increases fuel consumption at low speeds, but a higher speeds the effects are less noticeable. Don’t leave the air-con on all the time, you should run it at least once a week throughout the year to maintain the system and keep it in good condition.
Stick to the limits
Drive at or within the speed limit. The faster you go the greater the fuel consumption. Driving at 70mph uses up to 9% more fuel than at 60mph and up to 15% more than at 50 mph.
