Plus Heavy Duty 85W-140 Gear Oil

Lucas Plus Heavy Duty 85W-140 Gear Oil is a premium synthetic formulation designed for high-performance and heavy-duty applications. It is ideal for operators managing heavy transmission loads, differential stress, and sustained high-RPM operation across various vehicle platforms, including military and law enforcement.

This gear oil is developed from Lucas Oil's Heavy Duty Oil Stabilizer technology, providing superior protection and thermal stability in extreme operating conditions. The 85W-140 viscosity grade ensures optimal film strength across a wide temperature range, which is crucial for consistent protection during cold startups and sustained heat cycles.

Operators of heavy-duty trucks, tactical vehicles, off-road platforms, and industrial equipment will benefit from the robust additive package that reduces gear wear and extends component life under shock loads and continuous duty cycles. This formulation resists viscosity breakdown and oxidation, maintaining reliable lubrication in demanding environments.
