Why this is the answer
The correct answer in the official bank: Change gear according to the correct speed and road conditions and avoid high engine revolutions.
Choosing the right gear for your speed and the road keeps the engine at efficient revolutions, and smooth driving without high revs saves a lot of fuel. Staying in the lowest gear makes the engine spin fast and wastes fuel. Using fuel with lower octane than required saves nothing and can cause engine knocking and damage.
