What is the appropriate speed control for the Buick Regal during the break-in period?
2 Answers
The Buick Regal generally requires a break-in period of 3,000 to 5,000 kilometers to allow the vehicle to enter normal working conditions and achieve optimal performance standards. It is recommended to keep the speed below 60 kilometers per hour, and the engine speed should not be too high, preferably not exceeding 3,000 RPM. During the break-in period, the following precautions should be noted: 1. When cold starting, there should be a warm-up process for the engine. Wait until the water temperature changes before driving, usually about 3 minutes. 2. The vehicle should be loaded according to the specified capacity, preferably not exceeding 70% of the maximum load. 3. Sudden braking can cause significant impact damage to the new car's engine, braking system, and chassis. Drivers should anticipate situations in advance and reduce speed and gear accordingly.
When I first got my Buick Regal, I was extra cautious and kept the speed under 100 km/h for the first 2,000 kilometers. It wasn’t about avoiding speeding tickets—it was mainly to let the new engine parts break in properly. I remember once on the highway, I eased off the throttle as soon as the tachometer hit 2,500 rpm. Honestly, during the break-in period, the real concern isn’t high or low speeds but sudden acceleration or braking, which is particularly harsh on the transmission. In city driving, 60-80 km/h was ideal, and on long downhill stretches, I’d even switch to manual mode to use engine braking. Oh, and for the first three oil changes, I did them 500 km ahead of schedule—the dealership mechanic said there’d be more metal particles in the oil during break-in, so changing it early was better for the engine. Now, after 60,000 km, my car’s fuel consumption is 0.8 L/100 km lower than my friend’s same model bought around the same time.
