Synthetic Gear Lubes
 AMSOIL Severe
Gear™ Synthetic EP Gear Lubes are specifically engineered for high
demand applications. Their superior lube “film strength” combined with
extra additives protects gears and bearings
from
scoring and wear. They resist high heat and possess excellent cold flow
properties. AMSOIL Severe Gear Synthetic EP Gear Lubes outperform all
conventional gear lubes. AMSOIL SEVERE GEAR® provides performance beyond
that possible with conventional gear oil. These AMSOIL custom products
offer superior gear and bearing protection, better friction and heat
reduction, increased efficiency and extended service life.

AMSOIL SEVERE
GEAR® Synthetic Extreme Pressure (EP) Lubricants are premium grade gear
oils specifically engineered for maximum performance in severe duty
applications. These state-of-the-art AMSOIL formulations feature an
exclusive blend of high viscosity, shear stable synthetic base oils and
an extra treatment of high-performance additives. AMSOIL SEVERE GEAR®
Synthetic EP Lubricants maintain their viscosity for long-lasting
protection against metal-to-metal contact. The proprietary
AMSOIL additives form an iron-sulfide barrier coating on gear surfaces,
providing the ultimate line of defense against wear, pitting and
scoring. AMSOIL SEVERE GEAR® lubricants help prevent “thermal runaway” —
a phenomenon caused by a lubricant’s inability to control friction and
increased heat under high-stress conditions. By controlling thermal
runaway, AMSOIL SEVERE GEAR® Synthetic EP Lubricants inhibit rapid
lubricant degradation and component damage. Equipment runs better and
lasts longer with AMSOIL SEVERE GEAR® Synthetic EP Lubricants.

Motorcycle Air and Oil Filters
|
Ea Motorcycle Air Filters
 The filtration
media in the Ea Motorcycle Air Filter is pleated and has
epoxy-coated wire on the face and back of the media for additional
strength and stiffness. High-quality plastisol potting compounds
bond the pleat packs to the plastic or aluminum side plates. The S&S
style round filters are manufactured with high-quality plastisol that bonds the media to the wire backing and sealing area.
more information
Superior Filtration
The synthetic
nanofiber media featured in AMSOIL Ea Motorcycle Air Filters have
sub-micron diameters and small inter-fiber spaces, resulting in more
contaminants being captured on the surface of the media and lower
restriction. Cellulose, wetted gauze and foam filters are larger and
have larger spaces between the media that cause contaminants to load
in the depth of the filter, resulting in airflow path plugging,
higher restriction and lower capacity.
Cleanable For Long Service Life
AMSOIL Ea
Motorcycle Air Filters are cleanable, providing unsurpassed
protection and long service life. AMSOIL Ea Motorcycle Air Filters
should be cleaned every year or according to operating conditions.
Operation in extremely dusty or dirty environments may require more
frequent cleaning. Ea Motorcycle Air Filters should be changed every
four years.
| |
Superior Alternative
AMSOIL
currently provides eight Ea Motorcycle Air Filters manufactured for
the most popular Harley Davidson models from the years 1988 to 2006,
including motorcycles equipped with S&S carburetors and air cleaner
housings.
Ea Motorcycle Oil Filters
 Ea Motorcycle
Oil Filters feature a specially constructed silicone anti-drain back
valve and a nitrile sealing gasket to go along with the
full-synthetic Ea nanofiber media. The anti-drain back valve provides
excellent protection during startup and remains flexible in all
temperatures, and the nitrile sealing
gasket resists chemical
breakdown, providing excellent durability and ensuring long filter
life.

Superior Filtration
The unique
construction and full-synthetic media of AMSOIL Ea Motorcycle Oil
Filters allow them to provide unmatched performance in motorcycles
and other powersports equipment. EaOM Filters last longer, stop
smaller dirt particles and offer less restriction than other
filters. Ea Motorcycle Oil Filters provide filtering efficiency of
98.7 percent at 15 microns, outperforming the best
cellulose/synthetic blend media on the market. For maximum
protection, AMSOIL recommends changing Ea Motorcycle Oil Filters at
every oil change.

Fogging Oil & Gasoline Stabilizer
|
Engine Fogging Oil
 Two and
four-stroke motorcycles are commonly operated seasonally or
infrequently, and then stored for long periods of time. During these
periods of inactivity, and as a result of fluctuations in ambient
temperatures, water vapor can form condensate within the engine,
eventually becoming surface corrosion on cylinder liners, piston
rings, anti-friction bearings and steel/iron contact surfaces on
rotation seals.
AMSOIL Engine
Fogging Oil offers superior film retention, providing long-term
protection against corrosion and dry starts, extending engine life
and reducing operating expenses. Its
aerosol
spray formulation offers easy and clean applications, while reaching
more components and offering better distribution than straight motor
oil.

Gasoline Stabilizer
 It is
difficult to drain all of the fuel from equipment before storage,
and doing so would expose the system to other problems, including
the formation of rust and corrosion on the bare metal in the tank
and fuel system and drying and cracking of gaskets and seals. Some
fuels are pre-treated with oxidation inhibitors that allow them to
be stored for short periods without forming excessive deposits,
while other fuels have no inhibitors at all.
AMSOIL
Gasoline Stabilizer extending engine life and reducing operating
reduces the oxidation process that occurs when fuel is stored for
extended periods. It prevents the formation of varnish and sludge
which can clog injectors, stick floats and cause poor engine
performance. AMSOIL Gasoline Stabilizer is ideal for stored
seasonal equipment
such
as motorcycles, snowmobiles, lawnmowers and boats. The treat rate is
one
ounce with every 2.5 gallons of fuel. One bottle treats 40
gallons.

AMSOIL Quickshot SE
 Quickshot SE is a premium fuel
additive formulated to thoroughly clean and restore peak performance.
For use in all two and four-stroke
gasoline-powered engines, including motorcycles, snowmobiles, boats,
personal watercraft, ATVs, edgers, tillers, mowers, snowblowers,
chainsaws, generators and farm and construction equipment . It also
stabilizes fuel between uses and during short-term storage periods.
Its revolutionary technology focuses on three major fuel-related
issues plaguing small engines and powersports equipment: ethanol,
water and dirty pump gas.

Mothers Car Care
Products
 Airborne contaminants, corrosive pollutants and harsh environmental
conditions can all contribute to the premature aging of a car's
paint. Regular washing and waxing can easily make the difference
between a long lasting, luminous glow, or a dull, dumpy finish.
Proper vehicle maintenance involves cleaning paint and keeping it
clean, which is a much smarter choice, in the long run, than trying
to repair distressed, damaged paint. Mothers® offers a unique and
wide product line that includes everything needed to clean, polish
and care for vehicles.
