AMSOIL Products Improve Efficiency and Reduce Operating Costs
for Gerlach Trucking
AMSOIL INC., in conjunction with Gerlach Trucking of
Erskine, Minnesota, conducted a field demonstration of its Series 3000
Synthetic 5W-30 Heavy Duty Diesel Oil, Super Duty Oil Filters and
Dual-Gard filtration system equipped with BE-110 by-pass filtration
elements.
The test vehicle was a 1995 Freightliner FLD-120
powered by a Detroit 60 Series diesel engine and utilized mainly in
long-haul transports. The testing covered a two-year period and the
vehicle accumulated 212,326 total miles.
Evaluation Proposal
The goals for this demonstration included showing that the use of
AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil, in conjunction with
the AMSOIL Dual-Gard filtration setup and SDF Oil Filters, would
result in improved efficiency, reduced operating costs and
environmental benefits when compared to conventional petroleum
lubricants and filtration methods. As mentioned, the evaluation was
conducted using a 1995 Freightliner FD-120 equipped with a Detroit 60
Series diesel engine. The AMSOIL Series 3000 5W-30 Heavy Duty Diesel
Oil was sampled at the manufacturer's suggested oil drain intervals
and monitored through the use of oil analysis to ensure its continued
serviceability. The full-flow filtration units were also monitored and
replaced at 12,000- to 15,000-mile intervals, while the By-Pass units
were monitored and replaced at 24,000- to 30,000-mile intervals.

Summary
Overall, the demonstration was a success. After switching to AMSOIL
Series 3000 5W-30 Heavy Duty Diesel Oil (and later AMSOIL 75W-90 Gear
Lube in the differentials and Power-Shift Transmission Fluid in the
Transmission), the truck experienced significant declines in wear
rates and an eight percent increase in fuel economy. The pictured
charts show individual rates of wear throughout the two-year
demonstration. As the engine wear rates were reduced, operating
efficiency rose, leading to an increase in the life of the engine and
decreasing operating costs. Even with 212,326 miles on the oil, there
was no indication it needed changing. Because of the extended drain
capabilities of AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil, the
negative effects of used oil on the environment were also
significantly reduced. If it had been using conventional petroleum
diesel oil, which usually requires replacement approximately every
18,000 miles, this application would have required up to 12 oil
changes and 480 quarts of oil over the demonstration running time of
212,326 miles, compared to just one oil change and 40 quarts of oil
using AMSOIL Series 3000 5W-30 Heavy Duty Diesel Oil and Dual-Gard
filtration system. Overall, the data demonstrates that AMSOIL Series
3000 5W-30 Heavy Duty Diesel Oil is capable of providing extended
drain service for a period well beyond recommended drain intervals,
while also significantly decreasing wear rates, operating costs and
environmental waste.
