TOTEK Black Diamond HR–T 75W140 LSD API GL-4,5+
T 75W140 LSD API GL-4,5+ operates in a temperature range from -42°C to +500°C, which is optimal for performance in both low-temperature conditions and hot climates, as well as during intense heating of vehicle components.
TOTEK Black Diamond HR–T 75W140 LSD API GL-4,5+ is a lubricant with very high performance characteristics, created using synthetic base oils that are highly resistant to stress, with the addition of a powerful additive package. This makes the oil highly resistant to high temperatures and maximum loads, oxidation, and corrosion, while actively protecting gear pairs from scuffing and wear.
The viscosity of TOTEK Black Diamond HR–T 75W140 LSD API GL-4,5+ remains stable over a wide temperature range, which guarantees protection for transmission parts from the very first moments of operation.
Scope of application and differences between oils
The scope of application for TOTEK Black Diamond HR–T 75W140 LSD API GL-4,5+ includes axles and final drives operating under high-load conditions. The oil is used in auto and motorcycle sports, passenger and heavy-duty vehicles, as well as in commercial, highway, construction, industrial, agricultural, mining, and other equipment requiring this class of lubricant.
Other industrial gears, including hypoid and worm gears, operating under conditions of high speed/shock loads, high speed/low loads, and/or low speed/high loads.
The oil is designed for use in limited-slip differentials!
