What Causes Lack of Power When Climbing Hills During the Break-in Period of a New Car?
1 Answers
New cars are factory-filled with high-viscosity engine oil containing anti-wear additives. Due to the high viscosity of this oil, the engine experiences greater running resistance and lower power output. As a result, some models with smaller displacements may exhibit difficulty when climbing hills. This phenomenon disappears after the first maintenance when regular standard engine oil is used. Precautions during the break-in period of a new car: 1. Avoid driving at full load during the break-in period: Overloading increases the burden on the engine and transmission, leading to excessive power output from the engine and causing excessive wear on mechanical parts. Therefore, owners should be aware of their car's maximum load capacity and avoid full-load driving during the break-in period to extend its service life. 2. Pay attention to the curb weight: You can find two data points in the car's product manual or specification sheet: curb weight and gross vehicle weight. Curb weight, also known as empty vehicle weight, refers to the mass of the car when fully equipped according to factory technical conditions (such as spare tires and tools installed) and with all fluids filled.
