Super-Duty
Motorcycle Oil Filters
(SMF)
A full-flow Super-Duty Motorcycle Oil filter specifically designed for extended drain
intervals and severe service for motorcycle and ATV
applications. It provides superior efficiency and greater
capacity than other popular filters.
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 line.
Now, AMSOIL has developed a full line of oil
filters specifically designed for motorcycles and ATVs.
The Super-Duty 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 of time.
- Efficiency is the filter’s ability to
remove contaminants that cause engine wear.
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 said.
Each provides different levels of
filtration of the damaging dirt and dust particles that shorten
the life of a motorcycle engine.

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 intervals.
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.
