We all know that lubricity and the
ability not to break down under high temperatures are keys to good motor oil and
provide a longer life for the engine, but frankly we’ve always been confused by
all of the competing claims of companies hawking their products. What is the difference
between synthetic oil and regular oil? How do you tell the difference between super
oil and snake oil? To cut through the hype and promotional flak we searched out
a marine professional who knew something about the subject. We found Pat Studdert,
a 30-year veteran and president of Buffalo Marine Services. Here is what he had
to say…
**Buffalo Marine Service President, Pat Studdert,
says..**
Over 12 years ago Buffalo Marine sought to attain operational improvements of our
tugs and we looked into all of the various factors impacting big issues like downtime
along with matters such as fuel efficiency. One of the matters on our list of issues
to address was engine lubricants. Based on the experiences reported by Eddie Howard
with Field Services Equipment Company, and his recommendation, Buffalo Marine elected
to upgrade its engine oils to Royal Purple’s high-film-strength, long-life lubricants.

|:--|
**A Six-Month Trial**
As part of this change, used-oil analysis was begun on all engines to enable Buffalo
Marine to collect enough data so that we could make an informed choice about safe
oil-change intervals with the new oil. The first observation after changing to Royal
Purple’s motor oil was that engine operating temperatures dropped 5 degrees F. An
additional benefit was that fuel efficiency increased by 3-5 percent.
Ultimately, it was determined that oil and filter change intervals could safely
be extended from the existing 300 hours to an oil change every six months, regardless
of the number of hours of operation.
**Change Oil Once in 6 Months**
For some barges, this could be as long as 1,000 hours between oil changes. An exception
would be made if the oil ever appeared to be dirty on the dip stick, in which case
only the oil filter would be changed. Subsequent to changing the oil filter, the
oil would again look clean on the dip stick. The use of used oil analysis was suspended
immediately after establishing the six-month oil-drain intervals, which have been
ongoing for the past 12 years.
**More Years Between MOH**
The most significant benefit achieved by changing the oil to Royal Purple was that
engine repair costs dropped by twenty five percent (25%). In-frame repairs (replacing
all pistons, valves and heads) on our engines were common. In-frame repairs after
changing to Royal Purple were virtually eliminated. Also where the service life
of a diesel engine used to be about three years, diesel engines of all types are
now able
to run five to seven years before replacement. These gains have significantly
reduced costs and downtime and increased equipment availability.
**Other Royal Purple Products**
Based on these experiences, Buffalo Marine Service has upgraded to Royal Purple
lubricants in many other applications with excellent results. Maxfilm aerosol is
used on all hinges, controls, winch systems, etc., which has provided excellent
lubrication and eliminated rust, which is a common
problem in coastal environments.
Purple Ice additive in the engine radiators has provided additional engine temperature
reductions. Ultra-Performance Grease is used for all grease points. Every upgrade
has resulted in improved equipment reliability.
**Inexpensive Innovation**
Buffalo Marine Service believes being an industry leader requires innovation and
that innovation is necessary to meet the challenges of a highly competitive and
ever changing world. Some innovation can be complex and capital intensive. Others
can be as simple as purchasing and using innovative products in place of products
you already use. These are the easy ones to implement. But it first requires accepting
that meaningful choices exist and often looking past the higher initial purchase
price in favor of the higher overall value the product brings to the table. This was certainly the case for Buffalo Marine Service when it elected to embrace a change
in lubricants.
