Donaldson Endurance™ Filters
Frequently Asked Questions
|
|
Why is AMSOIL replacing
its SDF-70, 72, 73, 74, 75, 77 and 80
diesel oil filters with Donaldson®
Endurance™ brand filters? |
|
Donaldson® is the
premiere manufacturer of heavy-duty
filters for on and off road diesel
applications, and they are recognized
industry wide for producing
top-of-the-line diesel filtration
technology.
Although AMSOIL SDF filters provide
exceptional protection and performance
in diesel applications, extensive
research has determined that Donaldson®
Endurance™ filters provide an extra edge
of protection and performance. New,
sophisticated diesel engines designed to
meet today's stringent emission
standards benefit from superior
filtration, and the AMSOIL philosophy of
delivering top-of-the-line products
necessitated the partnership with
Donaldson® to carry Endurance™ filters. |
|
Why are Donaldson®
Endurance™ filters more expensive, and
what makes them better? |
|
Conventional oil filters
utilize cellulose fibers in their media.
Cellulose media have large openings that
allow contaminants to load inside the
filter and plug passage ways, and
cellulose filters have higher
restriction and lower capacity. AMSOIL
SDF oil filters utilize "lofted fiber"
media, which is a blend of synthetic and
cellulose fibers. The addition of
synthetic fibers allows AMSOIL SDF oil
filters to offer improved performance
over conventional filters.
The Donaldson® Endurance™
filter is constructed with full
synthetic media that is exclusive to
Donaldson®. Donaldson® synthetic media
have a controlled size, shape and
smaller fiber diameter that effectively
capture contaminants on the surface. The
exclusive Donaldson® synthetic media
design results in a full flow filter
that delivers extraordinary performance
with greater efficiency, capacity and
flow. Donaldson® Endurance™ filters are
98.7 percent efficient when faced with
15 micron contaminants, and they are 50
percent efficient when faced with seven
micron contaminants. The smallest
particle that can be seen with the naked
eye is around 40 microns. |
|
Why is wire mesh used in
Endurance™ oil filters? |
|
Because synthetic media
is soft compared to cellulose, the wire
is necessary to add structural support. |
|
What are the benefits of
Donaldson® Endurance™ filters? |
|
Donaldson® Endurance™
filters are capable of extending oil
filter service life. They offer greater
capacity compared to conventional
filters, allowing them to hold more
contaminants before they require
changing.
Donaldson® Endurance™
filters are more efficient than
conventional filters. Because dirt is
the number one cause of wear, it is
critical to stop as much as possible to
prevent wear and extend engine life.
Donaldson® Endurance™
filters offer greater flow. Greater flow
reduces restriction, allowing oil to be
easily pumped to vital components, while
also aiding cold weather starting. |
|
Do Donaldson® Endurance™
filters last as long as AMSOIL SDF
filters? |
|
AMSOIL recommends using
Donaldson® Endurance™ filters for the
same change intervals as AMSOIL SDF
filters. AMSOIL recommends new customers
who have never used AMSOIL SDF filters
follow vehicle manufacturer filter
change intervals until a safe filter
change interval can be established
through experience and oil analysis. |
|
Can Donaldson® Endurance™
diesel oil filters stop soot? |
|
Donaldson® Endurance™
diesel oil filters are full flow
filters, and they surpass the full flow
filtration requirements of both modern
EGR equipped diesel engines and older
diesel engines. However, as full flow
style filters, they are not designed to
remove soot. Soot particles are
extremely small, and special filtration
is required to effectively remove them. |
|
Where can Donaldson®
Endurance™ filters be used? |
|
Use Donaldson® Endurance™
filters in class 6, 7 and 8 vehicles.
 |
|
Are AMSOIL SDF-70, 72,
73, 74, 75, 77 and 80 oil filters still
available? |
|
These filters will remain
available as supplies last. |
|
An AMSOIL SDF-80 oil
filter is currently being used on a 5.9
Liter Cummins turbo diesel engine. Which
Donaldson® Endurance™ filter should be
used? |
|
Donaldson® Endurance™
filter ELF 7349 replaces the AMSOIL
SDF-80. Because it stops more dirt and
allows greater oil flow, the ELF 7349
offers superior protection for the 5.9
Liter Cummins turbo diesel engine. The
ELF 7349 may be used for the same
service intervals as the SDF-80, and it
delivers all of the performance
advantages stated earlier.

demonstrate the superior performance
benefits of Donaldson® Endurance™ oil
filters in the areas of efficiency,
capacity and flow restriction:
