Donaldson Endurance Oil Filters Q and A
- Why is AMSOIL replacing its SDF-70, 72, 73, 74, 77 and 80 diesel oil filters
with Donaldson Endurance™ brand filters?
Donaldson is the premier manufacturer of on- and off-road diesel applications,
and they are recognized industry wide for top-of-the-line diesel filtration
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 performance and protection. New, sophisticated
diesel engines designed to meet today's stringent emission standards benefit from
- Why are Donaldson Endurance™ filters more expensive, and what makes
Conventional oil filters use cellulose fibers in their media. Cellulose media
have large openings that allow contaminants to load inside the filter and plug
passageways, and cellulose filters have higher restriction and lower capacity.
AMSOL 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
7-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 extended 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 can be established through experience and oil analysis.
- Can Donaldson Endurance™ 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 remove them.
- Where can Donaldson Endurance™ filters be used?
Use Donaldson Endurance™ filters in Class 6, 7, and 8 vehicles.
(See chart below.)
- Are AMSOIL SDF-70, 72, 73, 74, 75, 77 and 80 oil filters still available?
These filters will remain available as long as supplies last.
- An AMSOIL SDF-80 oil filter is currently being used on a 5.9L Cummins turbo
diesel engine. Which Donaldson Endurance™ filter should be used?
Donaldson's 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 5.9L Cummins turbo diesel engine. The ELF 7349 may be used
for the same service interval as the SDF80, and it delivers all of the performance
advantages stated earlier.
