While driving less or choosing public and active transport is ideal to cut fuel use, it is not always practical for everyday life. These practical, easy fuel‑saving tips will help you get the most out of every litre.
- Air conditioning vs windows - Air conditioning does use fuel, but the most efficient choice depends on your speed:
- Low speeds: Open windows are more efficient.
- High speeds: A/C is usually better than open windows.
Driving above60 km/h with the windows down creates aerodynamic drag, forcing the engine to work harder and increasing fuel consumption. On highways, keep the windows closed and use the A/C at a moderate setting rather than max cooling.
- Drive smoothly - Smooth, steady driving can save a surprising 10-40% in fuel. Fuel spikes every time you:
- Accelerate hard
- Brake suddenly
- Speed up and slow down repeatedly
Using cruise control on highways helps maintain a steady speed and avoids unnecessary acceleration.
- Avoid idling - If you're stopped for more than 30 seconds (e.g. school pick up), turning the engine off saves fuel.
Many modern cars have start–stop systems designed for frequent restarts, supported by special batteries that can power accessories while the engine is off.
Petrol cars built from the early 2000s onward don't need to warm up. Start the engine, pause briefly, and drive off gently.
- Remove unnecessary weight - Every extra 50–100 kg increases fuel use. Lighter car = less fuel burned.
Consider removing:
- Tools you don't need
- Sports gear
- Boxes, equipment, or other items you rarely use.
- Keep tyres properly inflated - Under‑inflated tyres increase rolling resistance. Correct tyre pressure can improve fuel efficiency by 3–6%. Check your tyre pressure regularly, especially before long trips.
- Plan your trip - Combine errands into one logical loop instead of making multiple short trips. A warm engine uses less fuel than a cold one, so grouping tasks into a single outing reduces consumption.
- Reduce aerodynamic drag - Remove roof racks, bike carriers, and roof boxes when not in use. Even when empty, they create drag and force the engine to burn more fuel.
- Keep your car maintained - A well‑maintained engine burns fuel more efficiently. Regular servicing not only reduces fuel use but also extends engine life.
- Oil changes: Typically every 10,000–15,000 km or 6–12 months, depending on your car and driving conditions. Ensure the oil filter is replaced as part of the service.
- Air filters and spark plugs: Usually replaced during major services (around 40,000–100,000 km, depending on the vehicle). Ask your mechanic to check them during minor services and clean or replace them if needed.
