GEAR-X 75w90HD synthetic gear oil is designed to take 80% more load
carrying capabilities than its competitors. GEAR-X 75w90HD is compounded
with the most recently developed additive system to provide the
ultimate in gear protection, from an E.P. wear, corrosive wear, and
shock load wear standpoint. A friction modifier is also employed to
reduce sliding friction resulting in lower energy requirements, thus
less drag, lower fuel consumption, and more horsepower.
GEAR-X synthetic gear oils offer both cold temperature advantages
(Pour Point is -45°F) and high temperature stability (Flash Point is
480°F). As a multigrade product meeting the low temperature viscosity
requirements of a SAE 75 W grade gear oil, but also meeting the
viscosity requirement of SAE 90 grade at operating temperatures. The
base is a unique combination of synthetic components that permits
meeting SAE 75w90 viscosity requirements without the need for a
Extended Lubricant Utility
GEAR-X 75w90HD gear oil spans a wide range of viscosity
classifications making it the first truly dependable “All Seasons” gear
oil. This means it will flow and properly lubricate at the lowest winter
temperature while providing the film strength for heavy duty operations
during boiling hot summer driving conditions. The advantages of such an
oil have long been recognized as evidenced by the universal acceptance
of multiviscosity motor oils.
Many lubricant manufacturers have previously offered multi-graded
gear oils. These oils have been formulated with the conventional
viscosity index improvers used to produce multi-vis oils. But these
additives, which work so well in motor oils, will not
Withstand the extreme pressures and shearing forces encountered in
normal gear operation. Consequently, the advantages of multi-grading are
lost after only a few thousand miles of service.
The new additive system used in GEAR-X 75w90RHD is almost totally
resistant to these forces. GEAR-X 75w90RHD shows virtually no change in
grade even after 50,000 miles of more of operation in heavily loaded,
hypoid axle drives. This means that in addition to the fuel savings
generated, GEAR-X will provide true year round performance in all
climates from arctic cold to desert heat. Additionally, it will provide
superior all around performance in virtually all applications calling
for gear oil rated from GL-2 through GL-6, in any viscosity grade from
75w, 80w90, or 90w. This can result in reduced gear oil inventories
allowing a single lubricant to replace as many as 4 or 5 separate oils.
GEAR-X 75w90HD gear oil is recommended for automotive type gear
service in manual transmissions, differentials, transfer cases,
over-drive units, oil lubricated wheel bearing, oil lubricated universal
joints, steering gear boxes, or any other gear unit calling for a high
quality heavy duty 75w90 hypoid type gear oil. GEAR-X.
75w90HD is also recommended for use in all limited slip type
differential designs. GEAR-X 75w90HD meets or exceeds performance
requirements of Military Specification Mil-L-2105B, Mil-L2105-C, and API
Specification GL-5, GL-6, and SAE Classification J306a.
