Fleet Maintenance - 17

says. "Every customer's duty cycle isn't the same.
We see opportunities for further optimization
based on what we see in the analysis. We have a
program built around that, called our Optimized
Oil Drain Interval Process, where we look at ...
used oil analysis data and can predict what the
end point of the oil is. [We] then move back to a
safe margin, knowing that everybody is not going
to change their oil exactly at the same time, giving
them a cushion to allow them
to safely run their equipment
but get as much uptime as
possible."
Humphrey confirms many
of the OEMs who support
these extended drain intervals
mandate that fleets conduct oil
analysis, at least on an initial
trial basis, to be sure the
extension is appropriate and
safe for the fleet.
However, some OEMs do not
support extended oil drain
intervals, so it is important to
check the terms of the manufacturer's warranty before
extending beyond the OEM
recommendation. If a manufacturer doesn't support extending
drain intervals, doing so may
void the warranty.

Conclusion

Advancements in engine oil technologies have come
a long way, especially in recent years. CK-4 oils have
made large strides in longevity, providing resistance
to oxidation, shear, and aeration, all while remaining backward compatible for engines before the
2017 model year. Meanwhile, FA-4s provide these
same protections, delivered in a more fuel-efficient
package for today's engines and beyond.

Seeing oil drain intervals of 80,000 miles is
something most people couldn't fathom even a
decade ago. Today it's made possible thanks to new
oil technologies, used oil analysis, and new filtration solutions. It is important to keep manufacturer recommendations in mind, however, and abide
by them when necessary to prevent voiding the
warranty. Whatever the interval may be, keeping
up with oil drains is imperative to a fleet's health.

Filters
One additional factor that can
help increase oil drain intervals is the filters used. New
filter technologies have been
developed to extend the filter
change intervals along with
the oil drain, all while removing contaminants from the oil
to keep the engine safe.
"Fleetguard LF14000NN
lube filters for the Cummins
ISX15 and X15 engines are
designed for 60,000-mile
service intervals while offering a high level of engine
protection over the life of
the filter," says Cummins
Filtration's Stephenson. "For
fleets utilizing the Cummins
X15 engines, the Cummins
OilGuard [used oil analysis]
program is an excellent way
to know exactly what is going
on inside your engine and may
allow you to extend your lube
filter change intervals up to
80,000 miles."
Other new technologies, such as Cummins
FleetguardFIT Filtration
Intelligence Technolog y,
provide real-time filtration
monitoring. Stephenson says
this uses integrated sensors
and data analytics to give
fleets visibility into filter and
oil life.
