Is it harmful to the car to run at 3000 RPM for a long time on the highway?

[Rhonda]

Running at 3000 RPM for a long time on the highway does not cause any damage to the car. Here are some relevant introductions about cars: 1. Engine: Under normal circumstances, the most suitable RPM range for the engine is around 2000 to 3500 RPM. For naturally aspirated engines, 3000 RPM is considered a medium RPM, so it does not harm the car. Additionally, apart from the normal wear and tear of the engine, running at 3000 RPM for a long time on the highway does not damage the car. However, when driving on the highway, the engine RPM should not be lower than 3000 RPM, because when the engine reaches 3000 RPM, the corresponding speed is around 100 km/h. If the RPM drops further, it may fall below the minimum speed limit on the highway, which not only violates traffic regulations but also increases the danger of driving on the highway. 2. Tachometer: Moreover, the tachometer in modern cars divides the RPM range into colored zones, mainly white and red. The white zone represents the safe RPM range, while the red zone indicates the dangerous RPM range.
