Can the X-Trail use fully synthetic oil?
2 Answers
The X-Trail can use fully synthetic oil. Comparison between fully synthetic and semi-synthetic oil: Fully synthetic oil is better. Compared to semi-synthetic oil, fully synthetic oil allows for more mileage within a single maintenance cycle and provides better engine protection. During winter, when the engine frequently starts in low temperatures, it is advisable to slightly reduce the maintenance cycle mileage. If the vehicle is not driven often and the mileage increases slowly, it is recommended to change the oil approximately once a year, as oil also has a shelf life. Prolonged presence in the engine can cause the oil to deteriorate, losing its protective properties. Engine oil: Each oil package displays the oil grade, such as a series of numbers like "5W-40." The number before the "W" indicates the oil's low-temperature fluidity—the smaller the number, the more suitable it is for cold weather. The number after the "W" represents the oil's viscosity at 100 degrees—the larger the number, the more suitable it is for high-temperature conditions.
The X-Trail can certainly use full synthetic oil. As a mechanic who has worked on various vehicles, I recommend it. Full synthetic oil has excellent fluidity, protecting the engine under extreme temperatures, reducing wear, and extending its lifespan. The newer X-Trail manuals typically recommend viscosities like 5W-30 or 0W-20—just check the API standard. After switching, the engine runs quieter and fuel consumption is slightly lower. A major benefit is the extended oil change interval of up to 10,000 kilometers, saving frequent trips to the shop. However, be cautious of counterfeit products—buy from authorized stores and ensure the seal is intact. Make it a habit to regularly check the oil dipstick level for long-lasting engine performance. Additionally, pairing it with timely filter replacements makes overall maintenance more hassle-free.
