Mobiltrans HD 30

Extra High Performance Transmission and Drivetrain Lubricants

Mobiltrans HD 30 and 50 are extra high performance transmission and drive-train lubricants engineered to meet or exceed the requirements of the rigorous Caterpillar TO-4 specification. This product line is uniquely designed to optimise the performance of powershift transmissions, gearboxes, and final drives. In hydraulic applications, they provide maximum protection even in high-pressure systems.

This technology combines selected base oils and an advanced additive system to deliver the precise performance parameters needed to maximise the productivity of construction, quarrying, and mining equipment operating in severe conditions. These products offer a clear performance advantage over the use of mixed fleet engine oils and previously used lubricants meeting Caterpillar TO-2.



Features and Benefits

Today's technology has vastly improved the performance capabilities of heavy-duty earth moving equipment in terms of load, speed, control, precision, and reliability through innovative power train designs. These designs have increased the requirements of power train fluids to deliver higher level of performance, productivity and efficiency. Friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and pumpability are features that must be optimally balanced to provide extended clutch life, slippage control, maximum drawbar loading, and high load operation even on an inclined slope at extreme temperatures. Mobiltrans HD 30 and 50 deliver exceptional performance in today's power train transmissions, drive trains, and hydraulic systems. Key benefits include:

FeaturesAdvantages and Potential Benefits
Balanced static and dynamic friction coefficientsOptimised clutch-friction retention and slippage control
Significantly improved clutch life compared to the best API CD/TO-2 engine oils
Compatible with latest clutch materials and elastomersLonger clutch life and higher performance
Increased levels of anti-wear and load carrying capabilityReduced gear wear and extended life in transmissions, gearboxes, and final drives
Greater productivity from reduced downtime
Excellent foam control protectionTop performance in wet brakes; excellent control of brake chatter
Excellent thermal and oxidation stabilityOutstanding hydraulic oil stability and protection against high-pressure pump wear
Very good low temperature pumpabilityReduced time from start-up to production


      Recommended by ExxonMobil for use in:

  • Heavy duty transmissions, gear boxes, final drives, and hydraulic systems used in off-highway applications
  • Off-highway industries including: mining, construction, quarrying, and agriculture
  • Manual, powershift, and automatic transmissions where Allison C-4 fluids (SAE 30 grade) are called for including Twin Disc and transmissions calling for Type F fluids
  • Most mobile equipment hydraulic applications
