Extra High Performance Drivetrain Lubricant

Product Description

Mobiltrans™ AST (All Season Transmission) is an extra high performance drivetrain lubricant engineered to meet the extreme performance requirements in heavy-duty off-highway transmissions, drive trains, and hydraulic systems. Mobiltrans AST 30 lubricant combines selected high quality base oils and an advanced additive system to deliver the precise performance parameters needed to help maximize the productivity of construction, logging, mining and agriculture equipment operating in severe conditions.

Features and Benefits

Today's technology has vastly improved the performance capabilities of heavy-duty off-highway equipment in terms of load, speed, control, and performance through innovative drivetrain designs. These designs have increased the requirements of drivetrain fluids to deliver higher performance, increased productivity, and reduced operating costs. For heavy-duty transmissions, friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and seal compatibility are features that must be optimally balanced to provide extended gear and synchroniser life, smooth shift control, fuel economy, and high load capability over a wide range of applications. Mobiltrans™ AST delivers exceptional performance in today's power train components including haul truck final drives with year-round application. The key benefits include:

Features	Advantages and Potential Benefits
Excellent frictional properties	Optimum clutch friction retention and slippage control, excellent anti-chatter brake performance, and extended clutch/brake life
Excellent load carrying, anti-wear, and EP performance	Great wear protection, extended component life, and reduced cost of operation
Outstanding protection against deposit formation	Help extend seal life, drain & service intervals
Maximum protection from corrosion of copper and its alloys	Protects and extends the life of synchronizers
Optimized thermal and oxidation protection	Extended transmissions and drive train life
Exceptional shear stability	Maintains effective viscosity and film strength during severe operation
Outstanding low-temperature fluidity and pumpability	Smoother shifting with quicker starts and reduced wear
All-season capability	Extended drain and service intervals with lower operating costs and higher productivity

Applications

Mobiltrans AST 30 is recommended for use in heavy-duty transmissions, gear boxes, differentials, final drives, wet brakes and hydraulic systems.

Mobiltrans AST 30 is suitable for use in equipment requiring Caterpillar TO-4 and TO-4M fluids and Komatsu equipment, requiring good micro-clutch performance.
