DOES YOUR
DIFFERENTIAL FEEL NEGLECTED?
| Many truck and SUV owners personalize their
vehicles with aftermarket products such
as lift kits, tires and rims, custom
grills, paint, wheel well flairs and engine
upgrades. While these upgrades and
accessories can increase engine
performance and add plenty of visual
appeal, they do nothing for extending drivetrain life. Most
people perform proper engine maintenance and
change their engine oil on a regular basis, but
according to one quick lube
business, only about 2 percent of its
customers purchase differential gear lube changes.
Sometimes this out of sight, out of mind differential
neglect results in costly gear failure, leaving the
motorist stranded on the highway. |
 |
There are two basic ways to change differential gear
lube. The old fluid may be drained or suctioned out and
the differential refilled with new gear lube, or the
differential cover may be removed to allow
more of the old gear lube to drain out and
allow access to the magnet inside the
differential. Unlike engines, differentials are not
equipped with filters. Instead, magnets that are open to
the entire gear lube sump are used to catch some of the
metal wear particles. When changing differential fluid,
the magnet should be cleaned to ensure the new gear
lube does not become contaminated.
After draining the old fluid and cleaning the magnet,
the differential cover should be re-installed and the
differential filled with the correct
viscosity grade of AMSOIL SEVERE GEAR®
Synthetic Gear Lube. The use of cleaning
solvents is not recommended. Initial differential
oil changes are recommended by some manufacturers
after the first 500 to 3,000 miles. Even when
vehicle manufacturers do not specify to change the
factory-fill gear lube to remove wear particles, it is a
good practice to do so. For optimum gear and bearing
life, AMSOIL recommends the factory-fill differential
gear lube be changed no later than the first 5,000 miles
with new or rebuilt gears, followed by 50,000-mile drain
intervals in severe service or 100,000-mile drain intervals
in normal service when using AMSOIL synthetic
gear lubes.
AMSOIL offers SEVERE
GEAR lube in three viscosity grades,
75W-90, 75W-110 or 75W-140, for turbo diesel or 4x4 trucks, SUV’s and
automobiles.

SEVERE GEAR 75W-90 (SVG)
replacescompetitive 75W-90 and 80W-90 gear lubricants and
delivers the optimum fuel efficiency and cold temperature
performance of all the SEVERE GEAR gear lubes. SEVERE
GEAR 75W-110 (SVT) replaces competitive
75W-110, 75W-90 and 80W-90 gear lubricants and
delivers increased fluid film wear protection over lighter
viscosity fluids and better fuel efficiency than 75W-140
gear lubes.
SEVERE GEAR 75W-140 (SVO) replaces
competitive 75W-140, 80W-140 and 85W-140 gear
lubes in applications where these viscosities are recommended
by equipment manufacturers.

If you drive a
rear wheel drive or four wheel drive vehicle, be sure to get some
SEVERE GEAR lube with your next Amsoil order.
