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

You answered correctly by choosing the first two answers. Efficient fuel consumption in a car with a manual gearbox is achieved by keeping your tyres at the proper inflation pressure, as under-inflated tyres increase rolling resistance and fuel use. Additionally, driving with an even style and at low engine speeds means you avoid unnecessary acceleration and high revving, both of which waste fuel. However, changing gears up as late as possible (at high revs) actually uses more fuel—it is more efficient to shift up earlier to keep the engine speed low. Remember these techniques for better fuel efficiency: maintain the right tyre pressure, drive smoothly, keep revs low, and shift up early.
