IRECT JOBBERS JOHN AND LEAH KAHRS of Hudson,
Iowa know the savings potential of AMSOIL
products; they also know that in these tough
economic times, school districts need to save
money as much as anyone.
Kahrs set his sights on making a customer of
the Hudson Community School system back in
2006. There were a couple superintendent
changes, but eventually Kahrs got an appointment
and gave a third presentation to new
superintendent, Roark Horn. Kahrs made the
presentation on the benefits and cost savings
potential of AMSOIL. Horn was intrigued and
agreed to register as a commercial account.
Kahrs first performed an oil analysis on all the
buses to ensure they were mechanically sound
and to get a baseline on the performance of the
conventional oils they had been using.
In February 2008, Kahrs began converting the
fleet of eight buses to AMSOIL Series 3000
Synthetic 5W-30 Heavy Duty Diesel Oil and
AMSOIL Ea or Donaldson Oil Filters.
Before making the switch to AMSOIL, the
school had a local school bus service shop perform
oil changes based on recommended 3,000 to 4,000
mile intervals. The buses hold between 18 and 20 quarts
of oil each. Combined, they are driven 64,000 miles
annually, which equated to 16 conventional oil changes.
Since the conversion in 2008, only one bus has had
the oil changed based on oil analysis results. This bus
is running a C7 Caterpillar and the oil was changed
after 20 months of service, 18,961 miles and 871 hours
of engine operation.
“While the mileage may not seem significant, the
results were pleasing,” Kahrs said. “These buses are
severe service, driving mainly rural gravel roads that are
soft, muddy and dusty.”
The other buses in the fleet still are running on the
first AMSOIL oil change. Oil filter changes and oil analysis
are performed annually or based on hours.
The school was spending $1,034 a year on conventional
oil and filter changes, not including the costs of
oil change labor or the driver’s time to take the buses
in for oil changes.
“The AMSOIL conversion was a one-time cost of
$1,238 and does not include oil change labor,” Kahrs
said. “No driver time is required as oil changes were
performed at the school bus shop after hours. This is
a $1,034 annual savings in oil and filters alone. The
savings to the environment is 80 gallons of used motor
oil and 16 used oil filters.”
The district’s three vans, automobile and pickup also
use AMSOIL products. “AMSOIL allows the vehicles to
run through the school year without needing an oil
change,” Kahrs said.
The buses and vehicles all use AMSOIL fuel treatments.
AMSOIL diesel fuel treatments keep the buses
running even in the cold of winter in northeast Iowa.
“Two years ago when neighboring school districts
could not get their buses started in the 34-degrees-below-
zero weather, Hudson’s buses all started and ran
their routes,” Kahrs said. “All during the cold winter, no
fuel-related or starting issues were experienced.
“AMSOIL can save commercial accounts time and
money and add value and productivity to their bottom
line. No matter how big or small your commercial fleet
is, AMSOIL will provide you with the performance and
savings you need.”
