What Are the Consequences of Aggressive Driving During the Break-in Period?
2 Answers
Aggressive driving before the break-in period is over is detrimental to the break-in process. It reduces the tight fit between components, negatively impacts engine performance, and shortens the service life. Benefits of the break-in period: The purpose is to allow the various mechanical components inside the engine to undergo mutual wear under relatively relaxed conditions, ensuring smooth operation in later use. Additionally, timely oil changes are necessary to remove metal debris generated during the break-in of internal engine components. Precautions during the break-in period: Avoid frequent use of emergency braking: Emergency braking refers to slamming the brakes to a complete stop in urgent situations or pulling the handbrake to its limit. Even under normal circumstances, excessive emergency braking is not advisable. However, emergency braking in a new car can significantly degrade the vehicle's braking performance over time.
I still remember when I bought a new car, I couldn't resist flooring the accelerator and slamming on the brakes constantly during the break-in period. As a result, after just 3,000 kilometers, the engine started making strange noises that sounded like a tractor, and fuel consumption skyrocketed from 10 liters to 15 liters per 100 km, costing me hundreds more in fuel every month. When I took it to the repair shop, the mechanic found that the piston rings and cylinder walls were worn out, and the major repair cost me over 5,000 yuan. That experience taught me that new cars need gentle treatment—keeping the RPM below 4,000 and accelerating and decelerating smoothly allows engine components to gradually adapt. Now, after five years, my car still runs like new. You really can't mess around during the break-in period, or you'll face high repair costs and endless troubles later.
