Does an engine speed of 5000 RPM damage the car when driving downhill in automatic transmission?

[EmmaFitz]

An engine speed of 5000 RPM when driving downhill in automatic transmission does not damage the car. The higher speed is fine as long as it is not maintained for a long time. Below are some related introductions about engine speed: 1. The engine operates within a certain speed range, and as long as the pointer does not exceed the redline area, there is no problem. The redline area is usually around 6000 RPM, so a speed close to 5000 RPM does not put too much pressure on the engine. 2. Generally, the higher the engine speed and the more frequently it is maintained at high speeds, the more severe the wear will be over time. Driving like this for a long time obviously carries some risks and will inevitably damage the car. This is because, at high speeds, the engine demands much higher cooling and lubrication. If the engine oil performance has degraded and the lubrication effect is poor, engine wear will accelerate significantly.
