Lucas Plus Heavy Duty 85W-140 Gear Oil is a premium synthetic formulation engineered for high-performance and heavy-duty applications where conventional gear oils fall short. Developed from Lucas Oil's industry-leading Heavy Duty Oil Stabilizer technology, this gear oil addresses decades of performance gaps in the automotive and industrial sectors. It delivers superior protection and thermal stability in extreme operating conditions, making it the preferred choice for operators managing heavy transmission loads, differential stress, and sustained high-RPM operation across military, law enforcement, and civilian tactical vehicle platforms.
The 85W-140 viscosity grade provides optimal film strength across a wide temperature range, ensuring consistent protection during cold startups and sustained heat cycles typical of demanding field operations. Lucas's proprietary anti-wear and anti-friction additive package reduces gear wear and extends component life under shock load and continuous duty cycles. The formula resists viscosity breakdown and oxidation, preventing sludge formation and maintaining reliable lubrication in transmissions, differentials, and transfer cases subjected to extreme pressure and temperature swings. At 7.87 lbs per quart, this concentrated formula delivers maximum protection per application.
Operators of heavy-duty trucks, tactical vehicles, off-road platforms, and industrial equipment benefit most from Lucas Plus Heavy Duty 85W-140 Gear Oil's robust additive package and thermal performance envelope. This oil is compatible with both manual and limited-slip differentials, helical gears, and spiral bevel gearsets found in military transport, law enforcement pursuit vehicles, and civilian 4x4 platforms. Recommended for gearboxes and differentials where OEM specifications call for 85W-140 viscosity; verify compatibility with vehicle manufacturer guidelines before use. Keep a supply on hand for field maintenance and preventive service cycles in harsh desert, arctic, and mountainous terrain.
