Supreme Gear Lube SAE 75W-90 is a parasynthetic, shear stable, thermally stable, thermally durable, multigrade
gear lubricant recommended for use in all types of automotive gear drive applications that require a
gear oil to operate under severe, wide ambient temperature ranges.
Supreme Gear Lube SAE 75W-90 is blended from the finest quality, severely hydrotreated, polyalphaolefin
(PAO) synthetic base fluids and severely solvent refined, severely hydrofinished, high viscosity index, 100%
pure paraffin base oils available. This unique combination provides Supreme Gear Lube SAE 75W-90 with
the following advantages:
1. Excellent low temperature properties which results in the bearings and gears being instantly
lubricated at sub-zero temperatures the moment they start turning.
2. Superior oxidation stability.
3. Excellent resistance to thermal degradation
4. Excellent hydrolytic and demulsibility characteristics
5. Low coefficients of traction, which result in fuel economy benefits.
6. A high viscosity index
7. Increased wear protection and longer gear life
8. Compatibility with all types of seals.
Blended into these para-synthetic base oils is a highly specialized, proprietary, non-corrosive, thermally
stable, thermally durable, multifunctional, extreme pressure additive package that provides the Supreme Gear
Lube SAE 75W-90 with the following advantages:
1. Enhanced thermal and oxidative stability and durability to handle operating temperatures
of 300F to 350F.
2. Excellent extreme pressure properties to protect the gears and bearings from excessive
wear and fatigue.
3. Prevention of the formation of sludge and carbon deposits that erode the seals.
4. Excellent seal compatibility.
5. Enhanced protection of copper, brass and bronze components from corrosion.
6. Non-corrosivity to brass, bronze and other non-ferrous metal parts.
7. Excellent protection of components from rust and corrosion in dry conditions and in the
presence of moisture.
8. Excellent resistance to water and moisture.
9. Excellent water separability characteristics.
10. Enhanced gear, bearing and seal cleanliness
11. Excellent resistance to foaming.
Supreme Gear Lube SAE 75W-90 contains an extremely shear stable, polymer type, viscosity index improver
which provides the Supreme Gear Lube SAE 75W-90 with a high viscosity index. These polymers expand as
temperature rises and contract as the temperature is lowered allowing the Supreme Gear Lube SAE 75W-90
to exhibit low temperature properties that allow the gears and bearings to be safely started at low ambient
temperatures and to have the proper viscosity needed at operating temperature and high ambient
temperatures in order to minimize wear. This temperature selectiveness also enhances the Supreme Gear
Lube SAE 75W-90’s high temperature oxidation stability.
The trend among automotive and industrial gear drive manufacturers is to operate the equipment at higher
speeds, loads, power densities and increased torque which results in higher operating temperatures and
extreme thermal stress on the gear lubricants.
Therefore, it is important that gear lubricants possess thermal stability and thermal durability characteristics.
Gear lubricants without these properties rapidly oxidize and decompose at high temperatures which results in:
the formation of sludge, varnish, and carbon deposits on the gears, bearings and seals; abraded seals,
premature seal hardening and brittleness; and loss of the extreme pressure additives’ ability to protect against
excessive wear, spalling and overall distress to the gears and bearings.
Supreme Gear Lube SAE 75W-90 resists oxidation and thermal stress at operating temperatures 150F to
175F higher than conventional gear lubricants because of the use of para-synthetic base oils and a thermally
stable, thermally durable, multifunctional, extreme pressure additive package. This combination provides the
following benefits:
1. A vast reduction in the formation of deposits.
2. Better heat transfer.
3. Excellent protection to the gears and bearings even under the most extreme thermally,
stressed operating conditions.
4. Less wear to gears, bearings and seals.
5. Increased oil seal life.
6. Lower operating temperatures
7. Less energy consumption
8. Longer lubricant and equipment life
9. Reduced equipment downtime and maintenance costs
Most gearing is designed to perform under hydrodynamic lubrication conditions. That is, a full fluid film must
separate the metal surfaces of the gears and bearings during operation. However, during periods of cold start
up, extremely high operating temperatures or high shock loading conditions this full fluid film can be
destroyed. Unless a boundary lubricant is present in the gear lubricant when this full fluid film is destroyed,
wear can take place.
Micron Moly®, a proven friction reducer, is added to Supreme Gear Lube SAE 75W-90 to provide boundary
lubrication. Micron Moly®, a liquid soluble type moly, plates itself to the metal surfaces of the gears and
bearings. Once plated, Micron Moly® forms an indestructible, long-lasting, solid lubricant film capable of
withstanding pressures up to 500,000 psi. This solid lubricant film, once plated to the gears and bearings, will
reduce friction, vibration, and wear, thus extending equipment life.
Micron Moly® also provides a smooth finished surface on all moving parts of the gear drives. This smooth
finish minimizes the action of cold welding and vibration, which can occur during start up after the gears have
been standing idle and during periods of high shock loading. This in turn lessens starting loads and peak
power demand; thus, resulting in a realistic fuel economy cost savings.
Supreme Gear Lube SAE 75W-90 contains the proper additive system to function and lubricate limited
slip, positraction, and high offset hypoid gear rear ends and differentials.
