Which action can help reduce fuel consumption?

• A. Changing filters regularly
• B. Keep tyres under-inflated
• C. Keeping the rev counter in the amber band
• D. Always using gears in sequence

Answer: (A)

Regularly changing filters helps reduce fuel consumption by keeping the engine breathing clean air and delivering fuel efficiently. A clean air filter lets air flow to the engine freely, supporting proper combustion. When the air filter is dirty or clogged, air intake is restricted, and the engine can end up burning more fuel to compensate or run less efficiently. Clean filters also help ensure stable fuel delivery, preventing inefficiencies that come with restricted flow. In short, reducing restrictions in the air and fuel paths helps the engine run more efficiently and use less fuel. The other actions described would not lower fuel use: under-inflated tyres increase rolling resistance and waste fuel; running with the rev counter in a high range typically means higher engine speeds and more fuel burn; and simply insisting on a particular gear sequence doesn’t guarantee you’re driving in the most fuel-efficient way.
