Can 0w30 engine oil be used in summer?
2 Answers
0w30 engine oil can be used in summer. The smaller the number before W, the better the fluidity of the lubricating oil at low temperatures, making it easier to start the car; the larger the number after W, the better the viscosity of the oil in high-temperature environments and the higher the strength of the oil film formed. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. The steps for changing engine oil are: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain plug after draining, and wipe it with a tissue to check for leaks; 3. Reinstall the protective plate, lower the car, and use a funnel to add engine oil to the standard position at the oil filler port.
I usually drive to and from work for commuting, and using 0W30 oil in summer is absolutely fine. 0W represents good low-temperature fluidity in winter, ensuring smooth cold starts for the engine, while 30 indicates moderate viscosity at high temperatures, protecting metal parts from wear. Even on hot days when the engine temperature rises above 100 degrees, this oil can still form a lubricating film to prevent overheating damage. My car has been running for three years, and even during long summer trips to the seaside, the oil temperature remains normal, and the engine stays quiet. Of course, avoid unnecessary modifications—just follow the vehicle manual's recommended oil. Most cars can handle 30 viscosity just fine. In summer, engine oil oxidizes and degrades more easily, so regular oil changes are far more important than obsessing over viscosity choices, ensuring a long vehicle lifespan while saving fuel and money.
