Long protective synthetic base oils in two ways to help improve the protection of lubricants: the stronger oxidation control: in industry standard tests lubricant additives, Stockman FB-SA exhibit traditional lubricants than the previous maximum length 30% of the service life. Continuous wear protection: Compared with standard SAE 15W-40 lubricant lubricating agents, such as synthetic lubricant technology Stockman FB-SA has a stronger flow characteristics. This means that they reach the critical freezing conditions under slight load 25% faster lubricating knowledge, it is possible to provide additional protection in the conventional lubricating oils which may not be pumping temperature. SAE 15W-40 meets the American Petroleum Institute API CH-4, the European Automobile Manufacturers ACEA A3 / B3, A3 / B4 grade-specific molecular formula intelligent engine starts instantly adsorbed film formed on the surface to provide a full range of outstanding special protection even in engine wear protection After stopping the movement can maintain lubricant _ lubricating agents _ and the run and the run by.
