🚗 Drive smoother, not slower. Aggressive acceleration can increase fuel use by 20–40%. Ease onto the accelerator, coast to slow down, keep your speed steady.

🔧 Check your tyre pressure. Two minutes at any petrol station, costs nothing. Under-inflated tyres can cost you up to 3% more fuel.

🗺️ Combine your trips. A cold engine uses significantly more fuel for the first few km. Three separate errands = three cold starts. Do them all in one go.
