HIGHTEC HYPOID EP S-LS 75W-140 is a fully synthetic, high-performance multi-grade hypoid gear oil. It is formulated for heavily loaded axle and transfer gears, including limited-slip differential units, where its high viscosity builds a strong, durable lubricating film with excellent thermal stability under extreme strain.

Purpose and specifications

This oil is designed for hypoid axle gears and transfer cases with or without a limited-slip differential. It meets API GL4, API GL5 and the limited-slip class API GL-5 LS, complies with MIL-L-2105 D, and carries approvals including MB 235.61, the BMW rear axle (Hinterachsgetriebeoel MSP/A) requirement, Ford M2C187-A, Ford 192-A and GM 1942386.

• 1L container for a complete axle or transfer-case oil change
• 75W-140 grade maintains a strong oil film from approximately -40 C up to very high operating temperatures
• Extreme-pressure additives protect hypoid gear teeth under heavy torque and shock loads
• LS additive package ensures smooth, chatter-free limited-slip differential operation

When to use / change?

Choose this oil where a high-viscosity 75W-140 GL5 LS hypoid gear oil is specified for your axle or transfer gear. Replacement intervals are typically around 60,000 km or in line with the manufacturer's service plan. It performs reliably from about -40 C to +150 C. Stored unopened in a cool, dry place, shelf life is approximately 5 years.

Frequently asked questions

Why a 75W-140 grade?
The higher viscosity provides extra film strength for high-torque axles, towing and performance applications running at elevated temperatures.

Is it safe for limited-slip differentials?
Yes, it meets GL-5 LS and contains friction modifiers tuned for limited-slip units.

Can it be used in transfer cases?
Yes, it is suitable for transfer gears that call for a GL5 hypoid oil of this grade.
