Heavy Duty Multi-Purpose ATF
July 2017
Castrol Heavy Duty Multi-Purpose Automatic Transmission Fluid (ATF) is a multipurpose power transmission fluid that
is designed for most power transmission and hydraulic systems to include passenger car and truck automatic
transmission, powershift transmissions in off-highway construction equipment, hydrostatic drives and industrial,
agricultural, mining and marine hydraulics.
Castrol Heavy Duty Multi-Purpose ATF has excellent anti-wear, corrosion resistance, friction retention, and oxidation
and thermal stability. In addition, it is inhibited against foaming, and the high viscosity index helps assure sufficient
body for proper lubrication in severe hot weather service, without excessive thickening low temperatures.
Features Advantages Benefits
High viscosity index. Maintains viscosity in severe hot
weather service.
Longer transmission, torque
converter, hydraulic system
life.
Low pour point (low temperature
fluidity).
Less wear in cold weather starts and
operation.
Longer transmission, torque
converter, hydraulic system
life.
Controlled frictional properties.
Maintains excellent frictional
properties (smooth shifting) for the
life of the fluid, a prime benefit of
the Dexron®III specification.
Transmission of power is smooth and
efficient and a noted long term
retention of these properties.
Better productivity through
efficient equipment
performance.
Oxidation stability
is excellent.
Resists chemical deterioration over long
service periods.
Longer equipment life under
severe service conditions.
Excellent anti-wear performance
when the application demands the
need for boundary lubrication.
Reduced metal-to-metal contact in
such applications as torque converters,
transmissions, vane pumps, etc.
Less maintenance. Keeps
downtime to a minimum.
Compatibility with rubber and
various friction materials, etc.
Not harmful to synthetic rubber seal
materials, compatible with such
material as sintered bronze and
graphitic surfaces.
Longer life for vital
components.
Minimal lock-up shudder. Smooth, consistent shift feel. Fewer operator complaints.
