How to Break in a New Manual Transmission Car?

[StJuliana]

The following are the methods for breaking in a new manual transmission car: 1. Avoid excessively high engine RPM. The break-in period is a process of smoothing and aligning the engine components. Excessively high RPM can damage the uneven surfaces of the crankshaft and bearings, so it’s important to monitor the engine RPM. Regardless of the gear, the RPM should generally not exceed 3,000, or 3,500 for automatic transmissions. 2. Avoid staying in one gear for too long. Some owners, in an attempt to speed up the break-in process, often drive in fifth or fourth gear, but this can lead to rapid engine aging. The correct approach is to use all gears appropriately and drive under various road conditions. 3. Avoid prolonged driving in low gears. During the break-in period, it’s best not to drive for extended periods in first or second gear. Prolonged use of low gears can damage the transmission. Instead, alternate between high and low gears for proper break-in. 4. Avoid overloading the car. The lighter the load during the break-in period, the better, as excessive weight can strain the engine. Also, avoid hauling heavy items. 5. Don’t perform the first maintenance too early. Some people prefer to service the car before the recommended first maintenance date, but this is not advisable. The recommended interval is scientifically calculated, so early maintenance is unnecessary. Generally, the first service should be done after 2,000 or 2,500 kilometers. 6. Avoid excessively long driving sessions. Don’t drive the new car continuously for long hours like a taxi. Limit driving to a few hours at a time and allow the car to rest. Avoid driving extensively on weekends or taking long trips, as this accelerates component wear and can severely harm the new car.
