Can 5w30 engine oil be used in summer?

[LeKarter]

Engine oil 5W30 can be used in summer. Here is the relevant introduction about engine oil: 1. The engine oil grade usually indicates viscosity and quality. 2. The viscosity of lubricating oil is mostly identified by SAE grade, and SAE is the abbreviation of "Society of Automotive Engineers" in English. 3. W stands for winter, and the smaller the number in front of it, the better the low-temperature fluidity of the engine oil, representing the lower ambient temperature available and the better protection ability for the engine during cold starts. 3. The number after "W" (after a horizontal line) is an indicator of the oil's high-temperature resistance. The larger the number, the better the protection performance of the oil at high temperatures. 4. The grade after the oil classification indicates its viscosity specification. For example, in "15W-40, 5W-40", "W" stands for Winter, and the smaller the number in front of it, the better the low-temperature fluidity of the engine oil, representing the lower ambient temperature available and the better protection ability for the engine during cold starts. For example, 5W represents resistance to external low temperatures of -30°C, while 20W is resistant to low temperatures of -15°C.
