The designation “SJ” on motor oil stands for a specific category set by the American Petroleum Institute (API) to classify the quality and performance standards the oil meets. The API established the SJ category in 1996 for gasoline engines, primarily aiming at vehicles manufactured in the 1990s. SJ oils are formulated to provide better high-temperature deposit control and lower volatility than their predecessors. However, with advancements in automotive technology and stricter emissions regulations, newer categories have surpassed SJ in terms of performance and protection. While SJ oils are compatible with many older vehicles, it’s crucial to use an oil that meets the manufacturer’s current specifications for your engine to ensure proper protection and efficiency.

Satin and polyester are not the same, but they are related in a specific way. Satin refers to a type of weave, characterized by its glossy surface and matte back, achieved by floating warp threads over weft threads in a specific arrangement. This weave can be made from various fibers, including silk, nylon, and yes, polyester. Polyester, on the other hand, is a type of synthetic fiber made from petroleum-based products. It’s widely used in the textile industry due to its durability, resistance to shrinking and stretching, and quick drying properties. So, when you come across polyester satin, it means the satin weave is made using polyester fibers. This fabric combines the smooth feel and sheen of satin with the practical benefits of polyester, but it’s not as luxurious as satin made from silk.
