👉 The Drivers Fluid, also known as the Drivers Fluid or Drivers Viscosity, is a critical component in engine performance and longevity, primarily influenced by temperature, engine load, and fuel quality. It is a complex mixture of additives designed to maintain optimal fluid properties under varying conditions, ensuring smooth engine operation and efficient combustion. Key drivers include viscosity index (VI), which measures the fluid's resistance to shear thinning; pour point, indicating the lowest temperature at which the fluid can flow; and viscosity at high temperatures, which affects lubricity and wear protection. Proper Drivers Fluid levels are essential for maintaining engine efficiency, reducing wear, and preventing issues like sludge buildup and oil leaks.
