How Often Should Full Synthetic Oil Be Changed?
2 Answers
Full synthetic oil can typically be changed every 10,000 to 12,000 kilometers or every six months, but the specific interval depends on the vehicle's driving conditions. Full synthetic oil has the following characteristics: 1. Better high and low-temperature performance; 2. Longer oil change intervals; 3. Suitable for harsher vehicle conditions; 4. High lubricity, low friction resistance, resistance to oxidation, and strong cleaning properties. Full synthetic oil is a type of artificially manufactured oil produced by chemically decomposing various natural substances and synthesizing them with other materials during the manufacturing process. Using full synthetic oil can extend engine life and reduce maintenance frequency.
I think the frequency of changing full synthetic oil mainly depends on your vehicle's manual recommendations. Generally, changing it every 7,500 to 15,000 kilometers or about once a year is the most common practice. I mainly use my car for commuting, and if the road conditions are normal with low speeds, the oil can last longer. However, I’d like to remind everyone not to just focus on the mileage; also pay attention to the oil’s condition. If the color darkens or there’s an unusual smell, it’s time for a change. Climate factors also matter—extreme summer heat or winter cold can affect the oil’s performance, so it’s best to check the dipstick regularly to see if the oil level has dropped. Don’t try to save money by delaying oil changes, as degraded oil can accelerate engine wear, leading to more costly repairs. Every time I go to the 4S shop for maintenance, I ask them to check the oil—professional inspections can catch small issues before they become big problems. Honestly, oil changes aren’t that expensive, and spending a bit to ensure driving safety is worth it.
