Direct Jobber Craig Hamrick of Macomb, Ill. has been a firefighter in charge of
fleet maintenance for 23 years.
“My wife and I have been Dealers since 2006 and became Dealers after seeing the
impressive results AMSOIL demonstrated in the fire department fleet,” Hamrick said.
The fire department is a commercial account of Dealer Glenn Mike Arnold, Hamrick’s
sponsor. “We have used AMSOIL lubricants since 2003 in the fleet,” Hamrick said.
The department has 11 vehicles and numerous small engines and generators, all running
with AMSOIL products.
“Glenn’s knowledge of AMSOIL products has helped us select the right products for
our needs. Every vehicle in our fleet has AMSOIL installed from front to back.”
AMSOIL Powers Generator
Macomb Fire Department generator at the main station is an Onan 150KW unit that
is powered by a Cummins QSB 6.7 liter diesel. The generator is equipped with an
AMSOIL Dual Remote By-Pass System and Ea Full-Flow and By-Pass Filters. For ease
of oil sampling, there is a petcock on one of the ports on the filter housing.
The engine is filled with AMSOIL Premium API CJ-4 5W-40 Synthetic Diesel Oil (DEO).
“The reason for choosing Premium 5W-40 over AMSOIL Premium 15W-40 Synthetic Diesel
Oil (DME) is the slightly better flow characteristics of the 5W-40 for cold-weather
startup,” Hamrick said. “While this unit has a block heater to keep the coolant
warm, the oil can still be fairly cold. This generator must go from stopped to running
with full electrical load in less than one minute. The cold flow characteristics
of AMSOIL diesel oil provide maximum protection and peace of mind for me and our
The fuel is also treated with AMSOIL Diesel Concentrate plus Cold Flow Improver
at each fill-up.
“The savings are substantial,” Hamrick said. “We only change oil based on oil analysis
now, where before we changed every three months or 250 hours. Fleet uptime is one
of the most important benefits for us. Our equipment must respond and perform at
maximum capability every time. The generator is just as important.”
Oil Analysis Proves AMSOIL Benefits
Hamrick said he was
a skeptic of extended drain intervals when he first was approached about AMSOIL
synthetics. However, he soon learned the saving potential of AMSOIL synthetic lubricants.
The department saves money through the reduction of waste oil generated, as well
as fewer costs for equipment repairs and services, both in time and labor.
The department regularly sends oil samples to OIL ANALYZERS as part of its maintenance
“The proof is in all of the oil analysis reports,” he said. “We can see by the results.”
AMSOIL lubricants are especially well-suited to emergency service vehicles where
every second counts. “You never know when you’re going to get that call, and there
isn’t a lot of extra equipment available,” Hamrick said. “We need our equipment
to be ready and able to perform.”
Even during the winter months, the generator has “instant oil pressure” when it’s
fired up, he said. “If you walk into our station all you will see in our maintenance
room is AMSOIL products.”
