How can you save fuel?

You answered correctly. Fuel saving can be achieved by maintaining at least the recommended tyre pressure from the owner's manual, as underinflated tyres create more rolling resistance and use more fuel. Removing unnecessary roof racks or ski racks also helps because they increase air resistance, which raises fuel consumption. These practices help improve vehicle efficiency and lower fuel use. Avoiding top gear, however, is not a fuel-saving measure; higher gears generally allow the engine to run at lower revs, which is usually more economical. Remember to keep tyres properly inflated and remove unnecessary external accessories to save fuel.
