What are the reasons for reduced engine power in Buick vehicles?

[LaMartin]

Here are the reasons for reduced engine power in Buick vehicles: 1. Poor fuel quality and fuel system blockage: Using low-quality gasoline (containing excessive impurities such as mixtures) is a common cause of this issue in many vehicles, regardless of whether they are new or old. Excessive impurities in gasoline can easily lead to carbon buildup, and in severe cases, can cause fuel system blockages, resulting in poor fuel supply and reduced power. Therefore, it is recommended that drivers always refuel at reputable gas stations and avoid choosing gasoline of uncertain quality for convenience or cost savings. The car's fuel filter should be inspected every approximately 60,000 kilometers to ensure it is not too dirty, preventing fuel system blockages. 2. Engine overheating: Insufficient engine oil, insufficient engine coolant, or malfunctioning engine cooling systems can increase the engine's load, leading to poor heat dissipation. Engine overheating can result in inadequate lubrication, increased mechanical wear, reduced engine power, and higher fuel consumption.
