APPLICATION – Classic Gear Oil EP 80W90 GL4
Classic EP 80W90 GL4 is suitable for classic gearboxes and differentials for which API GL-4 is specified.
The oil is ideal for rear axles that do not require GL-5 or hypoid-specific oil and provides safe lubrication for transmissions with brass or bronze synchronizer rings.
Thanks to its compatibility with overdrive systems and its protection against wear, pitting and high pressure, this oil has a wide range of applications in classic drivetrains.
Classic EP 80W90 GL4 is therefore the perfect choice for transmissions that require a reliable, non-aggressive GL-4 oil.
Description
Millers Oils Classic EP 80W90 GL4 is a high-quality mineral transmission oil specifically developed for classic vehicles with gearboxes and differentials requiring extra protection under high pressure. The oil is formulated with high-quality refined base oils and a carefully balanced package of EP (Extreme Pressure) additives, making it ideal for historic transmissions requiring GL-4 protection.
Thanks to its multigrade viscosity 80W90, this oil offers excellent performance at both low and high temperatures, resulting in smooth operation and a strong oil film under load.
Advantages
Multigrade formulation (80W90) for excellent performance during cold starts and high operating temperatures.
Safe for yellow metal components such as bronze and brass.
Suitable for transmissions with overdrive , where friction properties are crucial.
Strong EP protection against wear and stress.
Low friction contributes to less noise and smoother shifting.
