Reduce Consumption
What reduces fuel consumption?
CheckFuelPrices Editorial
Expert Written • 5 industry sources
Smooth, anticipatory driving is the single biggest reducer of fuel consumption — it can cut your fuel use by up to 30% compared with aggressive driving. Combined with simple vehicle maintenance habits, most UK drivers can meaningfully lower what they spend at the pump.
How You Drive Makes the Biggest Difference
Accelerate and brake gently:
Harsh acceleration and late braking waste the most fuel. Smooth, gradual inputs keep the engine working efficiently and reduce unnecessary fuel burn.
2
Maintain a steady speed:
Travelling at a consistent speed, especially on A-roads and motorways, significantly reduces consumption. Driving at 70mph uses up to 9% more fuel than at 60mph.
4
Read the road ahead:
Anticipating traffic flow so you slow naturally — rather than braking sharply — keeps momentum and avoids wasted fuel accelerating back up to speed.
3
Change up gears early:
Shifting up at around 2,000 rpm (diesel) or 2,500 rpm (petrol) keeps engine revs in the most efficient range.
2
Vehicle Maintenance and Loading
Keep tyres correctly inflated:
Under-inflated tyres increase rolling resistance and can raise fuel consumption by up to 3%. Check pressures monthly and before long journeys.
5
Remove unnecessary weight:
An extra 50kg in the boot can increase fuel consumption by around 2%. Clear out roof boxes, bike racks, and heavy items you don't need.
3
Service your vehicle regularly:
A poorly maintained engine — worn spark plugs, dirty air filters, old engine oil — burns more fuel. Keeping on top of servicing pays for itself in savings.
5
Reduce drag:
Roof racks and open windows at speed increase aerodynamic drag noticeably. Remove roof bars when not in use and use air conditioning sparingly.
4
Habits and Journey Planning
Avoid idling:
Sitting with the engine running uses fuel for zero distance. Turn off the engine if you expect to wait more than a minute or two.
2
Combine short trips:
Cold engines use significantly more fuel. Combining several short journeys into one allows the engine to warm up and run efficiently for longer.
3
Use air conditioning wisely:
Air conditioning can increase fuel consumption by around 8–10% in urban driving. At lower speeds, open windows are more efficient.
4
Cut Costs Further by Comparing Prices
Efficient driving helps — but so does where you fill up:
Even after optimising your driving style, petrol and diesel prices vary by 10p per litre or more between stations in the same area.
