The “SAE” in oil stands for the Society of Automotive Engineers. This organization sets the standards for the viscosity grades of motor oils, which indicate the fluidity of the oil at specific temperatures. Viscosity is a crucial quality in motor oils, as it affects the lubrication of engine components, fuel efficiency, and the oil’s ability to operate in extreme temperatures. The SAE rating, such as SAE 5W-30, tells you the oil’s viscosity or thickness and how well it performs in cold temperatures (the number before the W, which stands for Winter) and at the engine’s operating temperature (the number after the W).

Fabrics blended from polyester, rayon, and spandex are generally resistant to shrinking compared to 100% natural fibers like cotton or wool. Polyester is a synthetic fiber known for its durability and resistance to shrinking and stretching. Rayon, though made from natural materials, is processed in a way that also makes it less prone to shrinkage, especially when blended with other fibers. Spandex adds elasticity, enhancing the fabric’s shape retention. However, high temperatures during washing or drying can still cause minimal shrinkage or damage the fibers, so it’s recommended to follow the care instructions, usually opting for cold or warm washes and low heat drying.
