What does 'slow car' mean?

[IanAnn]

'Slow car' refers to a vehicle that has slow acceleration, sluggish starts, or is driven by someone with poor driving skills and slow reactions. Below are some related tips: 1. Regularly clean the car's radiator: Rust and scale buildup in the engine radiator are common issues. Scale and rust can obstruct coolant flow in the cooling system, reducing heat dissipation and potentially causing engine overheating or even damage. 2. Regularly clean the car's crankcase: During engine operation, high-pressure unburned gases, sulfur, moisture, nitrogen, and acid oxides from the combustion chamber can enter the crankcase through the gap between piston rings and cylinder walls. These mix with metal particles from long-term wear, forming sludge. 3. Change engine oil regularly: Regardless of quality grade, engine oil deteriorates over time. To prevent malfunctions, change the oil periodically according to usage conditions and maintain proper oil levels.
