Before we go into redlining of car engines, we need to know what a tachometer is.
The image above is called Tachometer.

The tachometer shows the rotation speed of the engine crankshaft.
It is measured in Revolution per Minute (RPM).

If the gauge reaches the Red Zone, it means that the engine is spinning at an abnormally high velocity which can cause complications to your vehicle.

Redlining the engine is not a safe practice for your car. it’s advised you don’t REDLINE your car.

Redlining your car can cause:

  • Overheating of the engine
  • Inadequate lubrication in the engine compartment
  • Excessive wear on the engine
  • Excess fuel consumption – the higher the RPM, the higher the fuel consumption.

All these mentioned above shortens the lifespan of a vehicle; it can easily cause an engine to fail. Don’t drive with the gauge pointing to the red zone. Always shift to a higher gear.
