What is the gear shifting mantra from first to fifth gear?

[VonCharlie]

The gear shifting mantra from first to fifth gear is: For speeds between 10 to 20 km/h, you can use either 1st or 2nd gear; between 20 to 30 km/h, 2nd or 3rd gear can be used; between 30 to 40 km/h, 3rd or 4th gear; between 40 to 50 km/h, 4th or 5th gear; and for speeds above 50 km/h, use 5th gear. As speed increases, the gear should be shifted up accordingly. Failing to do so will keep the engine at high RPM, leading to a rapid increase in fuel consumption. 1st gear is for starting; 2nd gear is a transition gear, suitable for speeds up to about 30 km/h; 3rd to 4th gears are for city driving, suitable for speeds up to 60 km/h; and 5th gear is for fast driving, suitable for speeds above 70 km/h.
