Some people won’t dare to rev their car engines above 3000rpm.They scare that they will spoil the engine or the engine will burst if they do so. This is totally wrong!! After the car engine reach the working temperature(refer to the water temperature meter of the engine), we can rev our engine as high as we want to red line of the engine but not beyond the red line. The car engine is designed for our to rev till red line. If not then what is the purpose of putting the red line at our rpm meter? Our engine will only get damaged if we put our engine at heavy load when the engine have not reach the working temperature. High rpm doesn’t mean putting high load to the engine and low rpm doesn’t mean the engine is at low load condition.

The reasons why we shouldn’t rev our engine when it is cold is because engine oil flows slower at cold temperature and couldn’t provide sufficient lubrication.

The engine load is depends on how hard we step on the accelerator to and how hard we accelerate our car. If we rev our engine hard to 3000rpm and change gear during cold engine, we will damage our engine even though we didn’t rev it high.

I have seen many people do this during cold engine. They step on the accelerator hard straight away after they started their car engine. This is a bad habit and should be avoided.
