Precautions for Summer Car Engine Oil and Fluids

Gasoline must never be downgraded in specification. Long-term use of low-grade gasoline can cause abnormal combustion, leading to knocking, increased fuel consumption, engine pinging, and loss of driving power. Especially in summer, as the external temperatures are high and heat dissipation is difficult, the distillation temperature of fuel volatility is higher. This makes it even easier for carbon deposits to form in the engine or for vapor lock to block the fuel line, which in severe cases may cause the engine to stop running. Here is some relevant information: 1. Oil grade classification: The number before the W represents the flow performance at low temperatures. The smaller the number, the better the starting performance at low temperatures. The number after the W represents the stability of the oil at high temperatures (i.e., the likelihood of thinning). The larger the number, the better the stability. 2. Precautions: When choosing engine oil, pay attention not only to the quality grade but also to the viscosity grade. First, select based on performance grade; then, choose the viscosity grade according to temperature and load.
During summer driving, engine oil should never be neglected. I often monitor the oil condition in high-temperature seasons, checking the dipstick to ensure the level is between the markings. If it's too low, I promptly add the same type of oil; otherwise, the engine may overheat and wear out. Secondly, I choose oil with the appropriate viscosity. High summer temperatures can thin the oil, so something like 5W-30 is more versatile and provides better lubrication for components. Don’t delay oil changes either—typically every 5,000 kilometers or six months. Oil degrades faster in the heat, and delaying changes can lead to increased carbon buildup and higher fuel consumption. Lastly, when parking, find a shaded spot to prevent the engine bay from overheating, and keep the cooling system clean, ensuring the radiator isn’t clogged. In short, these small habits can extend engine life, saving money and hassle. For summer maintenance, oil is the top priority.
There are three key points for summer engine oil maintenance: First, I check oil quality by rubbing the dipstick with my fingers – if it appears black and thin, it indicates an oil change is needed, as high temperatures accelerate oil oxidation and deterioration. Second, regarding oil selection, single-grade oil tends to thin out easily in summer, so I prefer synthetic or multi-grade oils like 10W-40 for their stable viscosity and engine protection. Third, perform regular checks – pop the hood monthly to inspect oil levels and prevent leaks or excessive consumption, while also checking coolant levels to avoid overheating. When refilling, use clean containers and avoid mixing different oil types to prevent chemical reactions that could damage components. I often remind myself that these small steps help avoid major repairs, ensuring safer driving.
