👉 The Mustang Fluid, also known as 4W-30, is a high-performance engine oil designed for use in performance vehicles like the Ford Mustang. It's formulated with a unique blend of base oil and additives that provide superior lubrication, protection against high temperatures, and improved fuel efficiency. This fluid offers excellent viscosity characteristics, meaning it maintains its thickness at both low and high engine speeds, ensuring consistent protection across the entire operating range. Its advanced additive package helps reduce friction, minimize wear, and prevent sludge and varnish formation, ultimately extending the life of the engine and transmission while delivering a smoother, quieter ride. Mustang Fluid is typically recommended for use in the 3rd to 5th gear range and is suitable for most Mustang models with automatic transmissions.
