What's the Difference Between Classic Full Synthetic and Advanced Full Synthetic?
2 Answers
Classic full synthetic and advanced full synthetic differ in terms of grade and application. Here is an introduction to the differences between classic full synthetic and advanced full synthetic: Different grades: Full synthetic oil can be used in a wider range of temperatures and has a longer service life. For the same oil film requirements, full synthetic oil can achieve the desired performance with a lower viscosity, while semi-synthetic oil requires a relatively higher viscosity to meet the same requirements. Different applications: Full synthetic oil can operate in a wider temperature range and can protect the engine with lower viscosity under the same working conditions, whereas semi-synthetic oil has relatively higher usage requirements.
I've seen many car owners ask about this at auto repair shops. Although both are labeled as full synthetic, Classic Full Synthetic and Advanced Full Synthetic differ in base oil grade. The classic version primarily uses Group III hydroprocessed base oils, offering stable performance suitable for most daily-driven vehicles. The advanced version upgrades to Group IV PAO or Group V ester-based oils with purer molecular structures—significantly better at resisting sludge at high temperatures and improving low-temperature fluidity. It provides superior protection for turbocharged engines and can extend oil change intervals beyond 15,000 km. Priced about 30% higher, the advanced variant is worth the premium if you frequently drive on highways or own German performance cars—the extra cost translates to extended engine lifespan.
