Big Trucks

With the help of Jeff Foster Trucking Inc. of Superior, WI, AMSOIL put its Series 3000
Synthetic 5W-30 Heavy Duty Diesel Oil (HDD), as well as its Dual-Gard filtration system, to
the test.

Ten 1996 Kenworth Class 8 tractors used as interstate freight hauling vehicles and
equipped with Cummins N-14 ESP3 diesel engines participated in the demonstration. Five
trucks equipped with AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, AMSOIL
BMK-12 Filter mounts and BE-110 By-Pass filtration elements utilized 120,000-mile oil drain
intervals,20,000-mile full- flow oil filter change intervals and 40,000-mile By-Pass filter
change intervals, while the other five trucks continued using petroleum motor oil, utilizing
20,000-mile oil and filter drain intervals.

The objective of the field demonstration was to prove that using AMSOIL
Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil, together with the AMSOIL Dual-Gard
filtration system, would result in a reduction in operating expenses when compared to the
use of conventional petroleum lubricants and filtration methods. Verification will be
demonstrated through increased fuel economy, extended drain intervals, reduced
oil consumption and reduced maintenance.

Both the AMSOIL motor oil and the petroleum product were sampled and tested at 20,000-
mile intervals in the areas of elemental analysis (including wear metals, contaminates and
additives), physical properties (including viscosity, total acid number and total base number)
and contamination (including water, solids, glycol, oxidation, fuel soot and fuel dilution). Oil
condemnation limits vary due to individual engine idiosyncrasies, operating conditions and
time the fluid has been in service.

The total mileage in this demonstration exceeded 2,548,580 miles,
with the average over-the-road mileage for each demonstration vehicle exceeding 217,527
miles. Even while making use of extended drain intervals, the protection and fuel economy
advantages of AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil met or
exceeded that offered by the petroleum products utilizing conventional 20,000-mile fluid and
filter change intervals. Furthermore, Jeff Foster Trucking saves $61.90 in lubrication
costs per vehicle by using AMSOIL products. Calculated to cover the entire Jeff
Foster fleet of 200 vehicles, that ’s a savings of $12,380.

The chart below demonstrates the fuel economy benefits of the AMSOIL products. Overall,
AMSOIL provided a 3.065 percent increase in fuel economy. For every 240,000 miles a
single Jeff Foster truck travels, it saves $1443 in fuel costs by using AMSOIL
products. Calculated to cover the entire fleet, that’s a savings of $288,600 at
an average diesel fuel cost of $1.30/gal. Jeff Foster Trucking currently uses
AMSOIL Diesel Oil in its entire fleet of
200 trucks.

$12,380 plus $288,600 is an overall savings of $300,950

Independent Laboratory testing shows AMSOIL Series 3000
synthetic 5w-30 Heavy Duty Diesel Oil in the engine and
AMSOIL synthetics in the drivetrain provide up to 8.2% more
miles-per-gallon than other popular lubricants provide.
For more detail See article 8.2% More MPG

What Does A Savings of 8.2% Mean?
Imagine a fleet of 100 Class 8 vehicles running an average 120,000 miles per year at an
average of 6.5 mpg with diesel fuel at $1.35 a gallon. The Fleet spends $2,492,308 on
fuel annually. Now imagine the fleet uses AMSOIL products and improves its
miles-per-gallon by 8.2%. The fleet now spends $2,303,427 on fuel annually.

That's a savings of $188,881

That money could buy a year's worth of AMSOIL synthetic lubricants for the fleet plus a
year's fuel for 3 to 6 trucks - with cash left over!

Gray began using AMSOIL Synthetic Heavy-Duty and
Marine 15W-40 Motor Oil (AME) in the E9-400 V-8
engine of his first truck, a 1984 Mack, after the engine
accumulated 45,000 miles. For 280,000 miles, Gray
changed his oil at 40,000 to 60,000 mile intervals
through his oil analysis reports showed, without
exception, that the oil was good for continued use. At
325,000 miles, Gray increased his oil drains to
100,000 miles.

Gray continued using AMSOIL AME in the engine of
his new truck, a 1990 Mack with an E7-400 engine.
With the new truck, instead of using 100,000-mile
drain intervals; Gray began basing his oil drains on
the findings of a used oil analysis program. He also
installed an AMSOIL By-Pass Oil Filter.

After 630,000 miles total and 409,000 miles without an
oil change, the E8-400 engine was torn down by the
local Mack dealership in December 1996 and its parts
were examined by an engine rater from a major oil
additive manufacturer.

FINDINGS
The engine showed light to moderate wear
throughout, just as an engine in similar service and
lubricated with conventional oil changed at 15,000- to
20,000-mile intervals would show. In fact, according

to the engine rater the parts he examined – cylinder
liners, pistons, rings, bearings, valve train
components – could have been put right back in
the engine and would have continued to provide
the good, dependable service they had provided all
along – after 409,000 miles without an oil change!

DISCUSSION
Many factors enable AMSOIL to be safely used 20
times longer than petroleum oils may be used.

Stability – AMSOIL synthetic Heavy-Duty Diesel and
Marine 15W-40 Motor Oil is far less prone to
thermal and oxidative breakdown than are
petroleum oils. Stability inhibits the formation of
carbon deposits, varnish, sludge and acids, which
helps the engine run clean and protected.

Neutralization ability – While rapid TBN loss often
renders conventional oils unfit for continued use,

Heavy-Duty Diesel and Marine

(Except for normal top polishing on the push tubes
and rater found, “no wear to speak of. These can g
right back in the engine and be used again.” The
push tubes were put back into the engine and
are in use today.)

15W-40 Motor Oil offers lasting protection
against engine corrosion.

WHAT MAKES AMSOIL SO GOOD?

"Synthetic basestocks, top-quality additives,
and most importantly, more experience
formulating synthetic motor oils than any
other oil company." says AMSOIL Director of
Technical Sales Dave Anderson. "AMSOIL
first put a long-drain synthetic diesel oil on
the market in 1975 and since then has
introduced three other long-drain
synthetic diesel oils."

DOES AMSOIL OFFER A
WARRANTY?

"Yes. AMSOIL warrants that the use of
its lubricants will not cause mechaical
damage to any mechanically sound
equipmentwhen AMSOIL products are
used in full compliance with AMSOIL
recommendations.

"AMSOIL Extended drain interval
recommendations are set at a minimum of
two times or more than the engine
manufacturerr's recommendations as
determined by oil analysis.

Viscosity retention – Some conventional
oils’ viscosity slips out
of specification when a few thousand miles of an oil
change. Amsoil Synthetic Heavy-Duty Diesel and
Marine 15-40 motor oil neither

(The rater found the valve train components
showed, “very light wear. Very good. [I] find no wear
on the shaft, which can be a heavily loaded area.”)

looses viscosity as shear-prone oils do, which
promotes wear during high temperature operation,
nor gains viscosity as oxidation-prone oils do, which
promotes wear during startup and cold temperature
operations.

ADDITIONAL DEMONSTRATIONS

Gray’s successful use of AMSOIL synthetic motor
oil in extended drain service is not unique. AMSOIL
has conducted demonstrations with fleet all over
North America.

In each instance AMSOIL has been proven safe
and effective in extended drain use. In fact, these
studies show that AMSOIL used in extended drain
interval programs consistently delivers lower rates
of engine wear than conventional oils used in
conventional drain interval programs.

Southern Over-the road fleet – AMSOIL was used
in Cummings class 8 engines for 75,000-mile drain
intervals; the fleet’s normal drain intervals were
15,000 miles.

Upper Midwest grocery fleet – AMSOIL was used in
Cummings NTC 350 engines for 79,000- mile drain
intervals; normal drain intervals were 12,000 miles.

Northern grocery fleet – AMSOIL was used in Detroit
Diesel Series 60 engines for 79,000-miles without a drain.

Virginia Beach, Virginia owner/operator –
AMSOIL was used in Cummings 350
engine for 325,350-miles
without a drain.

Midwestern trucking fleet – AMSOIL was
used in Detroit Diesel Series 60 engines
for 60,000-mile drain intervals; normal
drain intervals were 20,000 miles.

“I see no reason why it [the engine] couldn’t run on. –
Independent engine rater

Northern tier over-the-road fleet – In an ongoing
demonstration, AMSOIL Series 3000 5W-30 is being
used in a fleet of Cummings N-14 engines for extended
drain service with oil drains based on the findings of used
oil analysis. One change was performed at one year with
125,000 miles on the AMSOIL. The oil was
recommended for continued use. Normal oil drains were
done at 20,000 miles.

What Is Oil Analysis?

Oil analysis is a maintenance management tool that
allows users to monitor equipment condition for
maximum equipment life, maximum
lubricant drain interval length and optimal downtime
scheduling.

Oil analysis saves users significant money by
reducing equipment replacements and
repairs, reducing the volume of lubricant
purchased and destined for disposal and,
most of all, by reducing downtime.

Oil analysis customers like Haywood Gray
“Trendline” their oil analysis. Trendlining
involves comparing the results of previous oil
analysis reports to those of the most recent report
to establish trends in wear metals content, viscosity,
and acid content, acid neutralization ability and
other characteristics as specified.

Departures from established trends indicate a
change in engine or lubricant condition and the
information they provide may be used to correct
abnormal conditions before they cause damage or
failure.
