Is Starting at 4000 RPM Harmful to the Civic?

[LeSerenity]

Starting with the throttle at 4000 RPM is relatively harmful to the car. Reasons why starting at 4000 RPM is harmful: During driving, the optimal engine speed for most cars is around 2200-2500 RPM. Too low RPM makes the car sluggish, wastes fuel without moving, and harms the engine; too high RPM increases unnecessary fuel consumption and damages the engine. Recommended starting RPM range: A high engine speed during startup is normal. Generally, the engine speed can reach 1200-1500 RPM at the moment of starting. In cold weather, the engine speed may be even higher. However, during a cold start, the RPM should not be too high because the lubricant cannot reach the upper part of the engine. To reduce wear, keeping it below 2000 RPM is more appropriate. Once the engine stabilizes, the speed will drop to around 800 RPM.
