What Causes a Car's Power to Weaken?

[LaSamuel]

The reasons for a car's power weakening include carbon deposits, wear and tear, poor fuel quality, incorrect gasoline octane rating, and excessively high engine oil viscosity. Below is an introduction to engine oil-related content: Increased fuel consumption: When adding engine oil, the oil level should be between the upper and lower limits on the dipstick. If too much oil is added, the engine's temperature will rise, causing the oil to expand in volume. This leads to increased pressure in the oil chamber, greater running resistance, resulting in reduced car power and increased fuel consumption. Overfilling engine oil: Excessive oil can cause oil to flow through the crankcase vent pipe, increasing crankcase pressure. The oil seal may loosen under oil pressure, leading to oil leaks. Heat dissipation: Overfilling engine oil can affect the engine's heat dissipation.
