What does the FS version of Mobil mean?

It refers to Mobil 1 FS, which is one of the oil models in the Mobil lubricant series. Below is an introduction about Mobil FS: 1. Introduction to Mobil 1: Mobil 1 is a full synthetic motor oil brand featuring multiple proprietary Anti-wear technologies. Launched in 1974 by ExxonMobil, Mobil 1 became a globally applied automotive synthetic lubricant. At that time, its design exceeded industry performance standards, setting a new benchmark in lubrication technology. Mobil 1™ meets the latest API SN specification of the American Petroleum Institute, featuring various proprietary Anti-wear technologies that effectively help reduce engine wear, keep engines clean, and provide higher standards of engine protection and lubrication performance to meet the demands of modern engine technology and fuel economy. 2. History of Mobil 1: The birth of Mobil 1 originated from modern technology tackling natural challenges. In the 1960s, the U.S. government required ExxonMobil to develop a lubricant for aircraft landing gears that wouldn't freeze at -40°C. Researchers developed Mobil 28 synthetic aviation grease, which is still widely used in the global aviation industry today. Through continuous experiments, ExxonMobil discovered that innovative synthetic lubricants offered unique advantages in all aspects of engine protection: durability, fuel efficiency, strong power, and effective lubrication and cleanliness under varying temperature conditions.
Actually, I didn't understand what Mobil's FS meant before either, but later I learned it stands for Full Synthetic oil. Simply put, it's the top-tier series where the base oil is artificially synthesized at a molecular level, unlike mineral oil which is directly refined. The biggest advantage of this oil is its exceptional stability - it maintains good lubricity whether at -30°C or 40°C high temperatures. The most noticeable improvement after switching was much quieter engine during cold starts and smoother RPM climb. For drivers like me who cover 20,000-30,000 km annually, the oil change interval can be extended to around 10,000 km, making it more cost-effective than cheaper semi-synthetic oils in the long run. Just be careful not to buy counterfeit products - there are many refurbished barrel packages in circulation these days.
