Oil is the life blood of your
motorcycle engine. Your oil filtration system
keeps that life blood flowing and your ride
on the road.
For nearly 30 years, AMSOIL
INC. has offered state-of-the-art products Dealers
can sell with pride. In that time, the company’s
reputation has grown, along with its product
Now, AMSOIL has developed a
full line of oil filters specifically designed
for motorcycles and ATVs.
The SuperDuty Motorcycle Oil
Filters (SMF) reflect the newest technological
advances in the quest to meet the unique demands
of today’s high-stress motorcycle engines.
The three main functions
of any oil filter are flow, life and efficiency.
- Flow is the filter’s ability
to let the right volume of oil reach its intended
parts, with a minimum degree of restriction.
- Life is the filter’s capacity
to remain in service for a predicted amount
- Efficiency is the filter’s
ability to remove contaminants that cause
While each of those functions
is vital individually, there’s more to it.
“Remember, it’s more than just
flow. It’s more than just efficiency. It’s more
than just life,” said Dave Anderson, AMSOIL
Technical Sales Director. “They all have to
perform in unison. A filter is only as good
as its weakest link.”
Typically, oil filters are comprised
of cellulose, or paper, synthetic fibers, glass
fibers, or a combination of media.
“All of these fibers have a
different set of characteristics to them,” Anderson
Each provides different levels
of filtration of the damaging dirt and dust
particles that shorten the life of a motorcycle

Flow is gained through a media
that is open and free, while efficiency is gained
through media that is closed and difficult to
penetrate. The flow versus efficiency ” compromise
within the filtration system is the greatest
demand on an oil filter’s performance.
“Through our testing, we have
found the best for motorcycles, and automobiles,
is a blend of the three media – synthetic, cellulose
and glass,” Anderson said.. “That gives the
best overall performance. You have to look at
overall performance. How they do all the tasks
that you want them to do. A prudent consumer
must consider the total package.”
AMSOIL SuperDuty Motorcycle
Oil Filters provide the greatest possible balance
of that “total package” to provide the ultimate
in overall filtration performance.
The filters are available in
black finish, with several models also available
in chrome. The chrome models have a C designation.
They have a heavy-duty case
of drawn steel. The case is double-crimped at
the base with rolled-under seaming to withstand
extreme pressure surges and road shocks.
AMSOIL SMF are available in
spin-on and cartridge types.
These quality full-flow filters
are designed to allow extended filter change
AMSOIL INC. recommends the following
guidelines. When using an AMSOIL SMF with conventional
oil, change the filter at the manufacturer ’s
recommendation. When using an AMSOIL SMF with
AMSOIL Motor Oil, change the filter at twice
the manufacturer ’s recommendation or six months.
