What does car rpm mean?

Car rpm stands for the maximum rotational speed. Here is an introduction about the maximum rotational speed: 1. Each engine has a defined maximum rotational speed, which varies depending on the engine's structure. Increasing the rotational speed can enhance power output. The maximum rated rotational speed an engine can achieve usually corresponds to the maximum power output. In technical specifications, the power value of an engine typically refers to the maximum power it can achieve at its highest rotational speed. The maximum rated rotational speed is often easily reached when driving downhill in lower gears. 2. The maximum rated rotational speed is related to the engine's displacement, but generally, engine rotational speeds have been continuously increasing. Currently, the average rotational speed for a four-stroke engine at idle is between 600~800 rpm. As for the engine rotational speed at maximum power, depending on the engine's internal structure, displacement, and the number of cylinders, it usually ranges between 5000~6500 rpm. Racing cars can achieve an astonishing maximum rated rotational speed of 12000 rpm or even higher.

Is it necessary to change the transmission fluid for manual transmissions?

Manual transmissions require transmission fluid changes. The hazards of not changing the transmission fluid are as follows: 1. Starting: The car may experience weak acceleration when starting cold. 2. Heat dissipation: The transmission fluid may thicken, potentially blocking the transmission cooler, leading to excessively high transmission fluid temperatures and increased wear. 3. Aging: The transmission fluid may degrade, not only increasing fuel consumption but also shortening the transmission's lifespan. 4. Blockage: Particles may form in the transmission fluid, clogging the fluid passages and damaging the valve body, directly affecting system pressure and power transmission, resulting in delayed responses and harsh shifting.
