👉 The manufacturer fluid, also known as the base fluid or oil, is a critical component in internal combustion engines, serving as the primary lubricant that reduces friction between moving parts, such as pistons, crankshafts, and valves. It also helps dissipate heat, protect against corrosion, and maintain engine cleanliness by carrying away contaminants. Typically derived from petroleum or synthetic sources, the fluid's viscosity and chemical composition are carefully formulated to meet specific engine requirements, ensuring optimal performance, efficiency, and longevity. Manufacturers often specify the exact type and grade of fluid compatible with their engines to prevent damage and ensure proper operation.
