What is the engine oil specification for the Wildlander Hybrid 2.5 Luxury Edition?
1 Answers
The Wildlander Hybrid 2.5 Luxury Edition recommends using 0w40 engine oil with an SN rating, as long as it meets the purpose of protecting the engine. In fact, semi-synthetic oil can also be used as long as the rating is sufficient. 0w40 oil is suitable for all seasons. If you drive more frequently, you can use season-specific oils: 15w50 for summer and 0w30 for winter. The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The number after the "W" (after the hyphen) represents the oil's high-temperature resistance; the higher the number, the better the oil's protective performance at high temperatures. The specification after the oil grade indicates its viscosity. For example, in "15W-40" or "5W-40," the "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. For instance, 5W can withstand external temperatures as low as -30°C, while 20W can handle -15°C. The number after the "W" represents the oil's kinematic viscosity at 100°C; the higher the number, the higher the viscosity. 40 means the kinematic viscosity standard at 100°C is between 12.5mm2/s and 16.3mm2/s—it definitely does not mean the oil can be used below 40°C, as some rumors suggest. Oil grades are represented by a combination of two letters. The "S" series represents oil for gasoline engines, with specifications ranging from SA to SN (in alphabetical order, excluding SI). Each subsequent letter indicates better performance, with more additives to protect the engine. The further back the letter, the higher the quality grade. International brands often use oil grades above SF. The "C" series represents oil for diesel engines. If both "S" and "C" are present, the oil is suitable for both gasoline and diesel engines.
