You are driving a motor vehicle with a manual gearbox. How can you achieve efficient fuel consumption?

Your answer is correct because efficient fuel consumption in a manual vehicle primarily depends on two factors: keeping the tires properly inflated and driving smoothly at low engine speeds. Proper tire inflation reduces rolling resistance, which means the engine doesn’t have to work as hard. Driving with an even style and low engine speeds helps the engine operate efficiently without unnecessary fuel use. On the other hand, changing gears upwards late, as mentioned in option 3, causes higher engine speeds and increased fuel consumption, so it is not efficient. Remember, shifting gears early and maintaining steady speeds save fuel.
