5 Easy Ways to Save on Fuel Costs
Keep Your Tyres Properly Inflated
Driving on underinflated tyres can reduce fuel efficiency by up to 3%. Check your tyre pressure at least once a month—it only takes a few minutes and can make a real difference.
Drive More Smoothly
Sharp acceleration and sudden braking waste fuel. By anticipating traffic and driving steadily, especially on motorways, you could boost your fuel efficiency by up to 30%.
Lighten the Load
Carrying unnecessary weight – like tools, sports gear, or clutter in the boot – affects fuel economy. Removing just 45kg can save you roughly 1% on fuel.
Use Cruise Control on Motorways
Using cruise control on flat, open roads helps you maintain a consistent speed, improving your car’s efficiency on longer journeys.
Don’t Leave the Engine Running
Idling wastes fuel. If you’re parked or waiting for someone, switch off the engine—modern cars restart efficiently, and it’s better for your wallet and the environment.
