What is the optimal operating RPM for an engine?

[HaleyMarie]

Generally, an engine only needs to be maintained between 2000 and 3000 revolutions per minute. Most engines have an economical RPM range, and keeping the engine speed within this range ensures a comfortable driving experience and better fuel efficiency. Here are some related points: 1. Avoid prolonged high RPM operation: Running the engine at excessively high RPM for extended periods will increase fuel consumption, raise engine temperature, and accelerate wear. While an engine can reach its maximum RPM, prolonged operation at this speed is harmful. 2. Maintain reasonable RPM: When driving a manual transmission vehicle, upshift at higher RPM and downshift at lower RPM. The engine should not operate at excessively low or high RPM for long periods. Running the engine at too low an RPM can lead to increased carbon deposits. Therefore, drivers should simply keep the engine within a reasonable RPM range.
