Is There a Difference Between Premium Synthetic Oil and Full Synthetic Oil?
2 Answers
Premium synthetic oil and full synthetic oil differ in that full synthetic oil offers better high and low-temperature performance compared to premium synthetic oil; full synthetic oil has a longer oil change interval than premium synthetic oil; and full synthetic oil is more suitable for harsher driving conditions than premium synthetic oil. Below is relevant information about automotive engine oil: 1. Importance: Engine oil is crucial for the engine, as it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat within the engine. 2. Working Principle: When the engine is running, the oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. 3. Regular Replacement Needed: Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failing to change the oil for extended periods can accelerate engine wear.
As a seasoned driver with over a decade of experience, I can confidently say there's a noticeable difference between full synthetic and premium synthetic engine oils. Full synthetic is made from 100% synthetic base oils, offering higher purity and superior engine protection. It maintains stable performance in both high and low temperatures, reduces engine noise, and can extend oil change intervals up to 15,000 km. Premium synthetic oil might just be a marketing term—it's actually a semi-synthetic blend with lower costs but slightly weaker performance, typically requiring oil changes every 8,000 to 10,000 km. From my practical experience, full synthetic makes winter starts noticeably smoother and more fuel-efficient. While premium synthetic works fine for short city drives, it falls short on long highway trips. I recommend paying close attention to the SAE grade on the oil bottle rather than just the advertised name—choosing the right one can save you money and better protect your car.
