PRODUCT FEATURES AND BENEFITS
Acid and Corrosion Control
LubeMax Multigrade 15W40 CI-4 provides excellent control of acids by reducing acid accumulation and chemical corrosion of engine bearings. Harmful acids produced during fuel combustion are controlled through selected detergent additives that help neutralise them and protect metal surfaces against corrosion.
Reduced Engine Wear
LubeMax Multigrade 15W40 CI-4 offers a high level of engine wear protection in critical areas such as the valve train, piston rings, and cylinder liners. Its anti-wear additives are designed to form protective films at metal-to-metal contact points under different operating conditions, while soot dispersant additives help keep soot particles finely dispersed to reduce wear.
Deposit Control
LubeMax Multigrade 15W40 CI-4 helps prevent oil thickening and the formation of harmful deposits throughout the engine, including sludge and piston deposits. Its optimised detergent and dispersant additive system helps keep engines cleaner and operating efficiently.
