Smart Zone is one of the leading suppliers of base oil Group I according to the American Petroleum Institute (API), which contains less than 90 percent saturates and has a viscosity index greater than or equal to 85 and less than 120.
In the Smart Zone oil refinery, diverse grades of Base Oil are produced using solvent-refining paraffinic crude oil as below, with modern production facilities and using high-quality raw materials.
SN-150 base oil, a Group I mineral oil, offers a practical and cost-effective solution for a variety of industrial lubrication and processing needs. While not the ultimate performance leader, its characteristics make it a valuable component in specific applications. Here’s a closer look at its professional applications:
