Extreme MAKO 5W-40 (API CJ-4/SN) is a premium fully synthetic heavy-duty engine oil formulated using high-quality synthetic base oils and an advanced additive system engineered to deliver robust engine protection and sustained performance across a wide range of diesel and gasoline engine applications. This formulation is designed to provide excellent resistance to wear, oxidation, and thermal degradation, while effectively controlling soot-induced viscosity increase and deposit formation. It helps maintain engine cleanliness, viscosity stability, and reliable lubrication performance under severe operating conditions, including high load, elevated temperatures, and extended duty cycles.

Extreme MAKO 5W-40 supports extended drain intervals where operationally appropriate and contributes to improved engine durability and operational efficiency. It is suitable for modern engine technologies, including turbocharged and electronically controlled engines, as well as engines equipped with emission control systems requiring API CJ-4 performance levels.
