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 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 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.
- Traps Dirt Throughout Media Thickness
- Up to 100% More Capacity
- Up to 20% More Efficiency
- Built for Rugged Performance
- Heavy-duty Steel Case Withstands Extreme Conditions
- Assures Oil Flow With Relief Valve
- Prevents Oil Drainage During Engine Shutdown
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. |
