Highest PAO & POLYOL-ESTER content in the industry standard. Boron Nitride added for the efficient lowering of oil temperature to more effectively resolve the high oil temperature caused by the high-heat environment and slow driving in the urban areas and reduce engine loading. Moreover, the oil is infused with temperature-lowering and lubricating Bismuth to reach ultimate lubrication at the instant of starting the engine, which improves the common problems with average motor oil requiring reaching the working temperature for better lubrication and makes up for the internal engine component wear-in resulted before the motor oil reaches the working temperature. The GTL base oil comes from SHELL GLOBAL, GROUP IV PAO, and GROUP V POLYOL-ESTER come from U.S.A and BELGIUM. High-end ingredients are used to provide the experience of good oil. It is truly “certified” by the American Petroleum Institute (API) for the highest quality without deceiving consumers through the “conformity” of certification.
