Mobiltrans™ AST 30

Mobiltrans™ AST 30

Mobiltrans™ AST 30 and Mobiltrans™ AST Extra 20 are high performance multigrade transmission and drive train lubricants. These products are uniquely designed to provide low temperature and multi-season service in powershift transmissions, gearboxes, clutches , final drives and hydraulic systems. Mobiltrans AST 30 and Mobiltrans AST Extra 20 can be used in cold ambient temperatures down to -35ºC and -45ºC respectively.

 

The technology in Mobiltrans AST 30 and Mobiltrans AST Extra 20 combines selected base oils and an advanced additive system to deliver the precise performance parameters needed to 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, reliability and performance through innovative drive train designs. These designs have increased the requirements of drive train fluids to deliver higher performance, increased productivity and reduced operating costs. Friction control, wear protection, thermal stability, shear stability, rust and corrosion protection and seal compatibility are features of the drive train fluid that must be optimally balanced to provide extended clutch, gear and synchronizer life, smooth shift control and high load capability over a wide range of applications and operating conditions. Mobiltrans AST 30 and Mobiltrans AST Extra 20 deliver exceptional performance in today's drive train components and hydraulic systems. The key benefits include:
