Sagitar uses 5w40 or 0w40?
2 Answers
Sagitar is basically equipped with a turbocharged engine, and both 5w40 and 0w40 engine oils can be used. The choice of engine oil can be made based on the driving climate environment and engine characteristics. If the owner is in a relatively cold northern region, 0W40 engine oil can be chosen, as the 0w40 engine oil has lower noise during cold starts. For southern regions, 5w40 is sufficient to meet the needs. Here are the relevant introductions: 1. Introduction to engine oil models: The "W" in the engine oil model stands for winter use. The number "0" before the W indicates the critical pumping temperature of the lubricating oil. The smaller the number, the lower the viscosity of the lubricating oil, the better the low-temperature fluidity, and the lower the applicable minimum temperature. "0" has better low-temperature resistance than "5", so the price of 0w40 engine oil is higher than that of 5w40. The "40" after W represents the kinematic viscosity grade of the lubricating oil at 100°C. The numbers after W are both 40, indicating that the viscosity of these two engine oils is the same at 150°C. This means that in a hot engine state, using these two lubricating oils results in the same friction loss for the engine. 2. Selection of engine oil: The selection of engine oil is also related to the structure of the engine. Japanese and American car engines are designed to be more precise and are suitable for using engine oils with lower viscosity. Many German car engines are turbocharged and require engine oils with higher viscosity.
As an automotive engineer, I understand the importance of oil selection. The key difference between 5W-40 and 0W-40 lies in low-temperature fluidity: 5W is suitable for starts around -30°C, while 0W can provide rapid lubrication at -35°C or lower. Most Sagitar models' engine manuals recommend 5W-40, especially for turbocharged versions, as it delivers stable and reliable performance in moderate climates. However, if driving in extremely cold northern regions, 0W-40 can reduce cold-start wear and protect engine components. I'd advise first checking the owner's manual for oil certifications like the VW502.00 standard to ensure compatibility. Don't overlook oil quality—full synthetic oils withstand high temperatures better than mineral oils. The final decision depends on local temperatures: if winter temperatures frequently drop below -20°C, 0W is preferable; otherwise, 5W is sufficient and hassle-free. Choosing the wrong oil may accelerate engine aging, leading to costly repairs.
