Mobilube HD Plus 80W-90, 85W-140

Extra High Performance Commercial Gear Lubricants

Product Description

Mobilube HD Plus 80W-90 and 85W-140 are extra high performance commercial gear lubricants formulated from select base oils and an advanced additive system. These lubricants are engineered for performance in heavy-duty commercial transmissions, axles, and final drives where extreme pressures and shock loading are expected. They provide excellent chemical and thermal stability at elevated bulk oil temperatures, good performance at low temperatures, and have demonstrated good rust protection resulting from water contamination and wet conditions. They are recommended by ExxonMobil for applications where API GL-5 and MT-1 service is required. Mobilube HD Plus 80W-90 and 85W-140 share common formulations with Esso Gear Oil GX 80W-90 and 85W-140.


Features and Benefits

Today's heavy equipment applications place higher performance demands on drive train lubricants. Higher speeds, higher torque, and heavier loads require improved formulations to maximise equipment life and optimise operating costs. Longer service intervals place additional demands on the gear lubricant. Mobilube HD Plus gear lubricants are engineered to meet these challenges. The key benefits include:

FeaturesAdvantages and Potential Benefits
Excellent thermal stability and resistance to high temperature oxidationExtended gear and bearing life due to minimal deposits and longer seal life
Good protection against low speed/high torque wear and against high speed scoringIncreased load carrying capability and reduced operating costs
Excellent rust, staining, and corrosion protectionReduced wear and longer component life
Effective low temperature lubricationReduced wear and ease of start-up
Wide multipurpose capabilityReduced number of gear lubricants to simplify inventory and minimize misapplication
Good resistance to foamingMaintains film strength for effective lubrication
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination
