AMSOIL Field Study Proves Quality
of AMSOIL Synthetic 15W-40 Diesel and Marine Oil
to test the performance capabilities of AMSOIL
Synthetic 15W-40 Heavy Duty Diesel and Marine Oil (AME),
AMSOIL sought a partner with a fleet that operated in truly
severe conditions. The perfect match was found in Duluth,
Minnesota based Nordic Waste. Nordic Waste operated a fleet
of 10 International refuse haulers, providing trash and recycling
pickup to residential and commercial customers in the greater
Duluth/Superior Wisconsin region. Nordic's trucks operate
in the bitter cold of sub-zero winters, as well as on humid
summer days that can top out at over 90 degrees F. The fleet
runs 12 hours a day with frequent stops and redlined starts,
all while hauling up to 22,000 pounds of refuse and navigating
the seriously steep hills of Duluth.
As if the
geographic challenges aren't enough, perhaps the greatest
strain a refuse hauler's engine faces is dumping the refuse.
This action requires the engine to remain near or above redline
throughout the process and shakes the truck enough to nearly
lift the front tires off the ground. Nordic's trucks dump
their contents twice daily, challenging the oil's shear stability
on a regular basis.
truck used in this study is a 2006 International 7400 rear-loading
refuse hauler. This particular truck was chosen because its
Navistar DT466 engine employs a hydraulically actuated, electronically
controlled unit injector (HEUI) that uses engine oil pressure
to inject diesel fuel into the combustion chamber. HEUI systems
feature a variable pump (in addition to the oil pump) that
pressurizes the oil according to the fuel injection system's
needs, placing a considerable amount of additional strain
on engine oil. HEUI systems can raise oil pressure to as high
as 3,500 psi, creating great potential for shearing and adding
significant stress to motor oil that is already operating
in a severe environment. The HEUI system's reputation for
shearing less robust motor oils made the DT466 engine the
perfect choice for testing the durability of AMSOIL Heavy
Duty Diesel and Marine Oil.
Nordic Waste initially
installed Shell Rotella T 15W-40 Motor Oil (239 hours). AMSOIL
Synthetic 15W-40 Diesel and Marine Oil was installed for
the subsequent service interval and monitored via oil analysis.
AMSOIL Diesel and Marine Oil provided 983 hours of service
before oil analysis indicated it was time to drain the oil.
As expected, the results revealed that AMSOIL Diesel Oil contained
wear metals well below International's published condemnation
limits, even after nearly 1,000 hours of service.
8,000 hours of use, Nordic Waste brought its International
7400 refuse hauler to a certified International Truck mechanic
for a routine teardown. The engine was virtually free of deposits,
displayed minimal wear and received high praise from the mechanic
who performed the inspection.
AMSOIL Diesel Oil Saves Money
Nordic Waste save
a considerable amount of money just by using AMSOIL Synthetic
Diesel and Marine Oil rather than a conventional petroleum
product. The company has used inferior products in the past,
and its search for a high performance lubricant that could
withstand the punishment its fleet delivered led it to AMSOIL.
big hills, high heat and extreme cold we work in, nothing
has performed better," said Nordic Waste Owner Brian
Johnson. Prior to discovering AMSOIL, the conventional lubricants
Nordic used would shear out of viscosity grade rapidly and
need to be changed at approximately 200 hours of service.
Upon switching to AMSOIL Synthetic 15W-40 Diesel and Marine
Oil, Nordic Waste increased the average drain interval for
its trucks from approximately 200 hours to nearly 1,000 hours.
In addition, Nordic's use of AMSOIL Diesel Oil means the company’s
trucks are well protected and run at optimum fuel economy,
so they stay out of the shop and on the road.
less downtime and have seen reductions in costs associated
with engine overhauls and replacement parts," said Johnson.
"We buy significantly less oil, fewer filters and we
experience lower labor costs. Our biggest savings have been
the reduced number of engine overhauls and replacement parts."
Synthetic Motor Oils offer the longest drain intervals
on the market, unsurpassed protection and performance that
effectively extends equipment life and improved fuel economy,
saving customers money at the pump and reducing the nation's
dependence on foreign oil.
"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."
synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
NOACK Volatility Test
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
