As a rule: driving at low engine speeds lowers fuel consumption and reduces wear.
Use 1st gear to get the vehicle moving. Starting with the 2nd gear, accelerate rapidly. When accelerating, shift up before reaching high engine speeds.
When you reach the desired speed, shift into the highest applicable gear and drive with the engine speed as low as possible and at a constant speed.
If necessary, observe the gear shift indicator of the vehicle.
Use coasting
When approaching a red light, take your foot off the accelerator and let the vehicle coast to a halt.
For going downhill take your foot off the accelerator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
