How long is the break-in period for the new BMW 3 Series?

The break-in period for the BMW 3 Series is 2,000 kilometers. Break-in period precautions: Warm up before starting: Before starting, turn the key to the second position and wait 5-10 seconds before ignition. This allows the fuel pump to begin working, adjusting oil pressure and fuel injection volume. Starting after a few seconds benefits the car's starter motor and engine. After the engine starts, you can begin driving as long as stable RPM is maintained. Control your speed appropriately until the engine coolant reaches normal operating temperature, then you may drive normally. During the break-in period, avoid sudden acceleration and hard braking. New vehicle initial driving regulations: Avoid high-speed driving. When the throttle is fully open, speed should not exceed 80% of the maximum speed. Monitor the engine tachometer and speedometer to ensure both engine RPM and vehicle speed operate at moderate levels. Generally, the engine RPM during the break-in period should be strictly maintained between 2,000-4,000 RPM.
I recently picked up a brand-new BMW 3 Series and was thrilled. After carefully going through the user manual, I noticed it mentions a break-in period of around 1,500 kilometers. It advises against driving too aggressively in the first few hundred kilometers, keeping the RPM below 4,000, and avoiding sudden acceleration or hard braking, as the engine components are still settling in. The manufacturer claims this practice can extend the engine's lifespan and reduce early wear. I remember some seasoned drivers saying modern cars don’t require much break-in attention, but I believe it’s safer to follow the official guidelines, especially since the car is a significant investment. After the break-in, remember to schedule the first maintenance promptly, changing the oil and filter to keep the car running smoothly. Now, I drive gently during my daily commute, and the car feels more responsive. Indeed, by the later stages of the break-in, the acceleration has become noticeably smoother.
