Geely Binyue can use 5w30 engine oil. 5w30 represents the parameters of the engine oil, where 5 indicates the low-temperature fluidity of the oil—the smaller the number, the lower the ambient temperature it can be used in. 5 represents resistance to external low temperatures of -30 degrees Celsius, and 30 indicates the kinematic viscosity standard at 100 degrees Celsius is 30. This number represents the oil's high-temperature resistance index; the larger the number, the better the oil's protective performance under high temperatures. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance. Its functions are: 1. To alleviate friction and high temperatures; 2. To cool and reduce temperature; 3. To clean and purify; 4. To dampen vibrations and cushion impacts; 5. To prevent rust and corrosion.

I've been driving this Geely Binyue for over a year now, and I always use 5W30 oil for regular maintenance. It feels quite smooth. The car's user manual recommends this viscosity, which suits most weather variations across China - good fluidity for quick starts in cold winters and maintains engine protection without thinning in hot summers. I use fully synthetic oil, changing it every 7,000-8,000 km, with stable engine noise and reasonable fuel consumption. However, you'd better check your own car's manual for specifics, as there might be slight differences between model years or versions. Also, don't cheap out on no-name oils - choose major brands with API certification for safety and extended maintenance intervals. Just remember to check oil levels before driving to ensure everything's normal.

Engine oil selection should flexibly meet daily driving needs. 5w30 is quite common for many vehicles, and the engine design of the Geely Binyue suits it well, providing effortless cold starts and ample high-temperature protection. After using 5w30 a few times, I noticed quicker engine response and no unusual noises during long-distance high-speed operation. Always check the manual for recommended viscosity ranges—typically, 5w30 is the standard choice. If you drive in harsh conditions or have a turbocharged engine, full synthetic oil offers extra cushioning. Avoid mixing different brands of oil to maintain cleanliness. Purchase oil from reputable sources to avoid counterfeits, and during maintenance, the technician will check oil pressure and color.

From a novice's perspective, choosing engine oil is actually straightforward. My Geely Binyue manual recommends using 5W30 oil as the most suitable option, so I just follow that during maintenance. The 5W30 viscosity offers good adaptability, performing well whether for urban short trips or weekend getaways. Since oil quality affects engine lifespan, I opt for synthetic oil and change it more frequently - every 6,000 kilometers. When temperatures fluctuate sharply, like during the rainy season turning cold, it ensures smooth startups. The manual's first page provides detailed specifications for reference.
