Heavy Equipment Trader Magazine
QUESTION:We just got back from Gulfport, MS with some information from Charlie
Sims of Gulf Coast Filters. He showed us 17 purchase orders totaling
over $350,000.00 for filters for military equipment. I saw 17 states
involved in using Gulf Coast filters on mostly fuel, cleaning solvent
and antifreeze.
Since the US Air Force tested the filters eight Air Force bases have
ordered Gulf Coast filters installed on engine oil. With the US
Government involved its just a matter of time until more big civilian
companies start catching on. Shell Oil has them on their drilling rigs.
The filters work just as well on a boat, heavy truck or small car if
you can find a place for them and have the skill to install they.
You might find the following interesting:
"761,000 Mile Inspection"
On January 6th, 1997 the truck came into Covington Diesel of
Nashville TN for its second engine inspection. However, this time, a
more detailed inspection was performed by Covington Diesel technician
Ricky Cook and Shell Oil's Howard Hill. In addition to the standard
inspections performed at 500,000 miles, this time they also pulled #4
and #5 pistons and liners. The results - over 761,000 miles with only
two oil drains - and we still had an engine in "new" condition. One
very interesting observation during this inspection was the presence of
marking within the valve cover placed there by Howard Hill of Shell
Oil. While inspecting the valve cover at 500,000 miles, Mr. Hill
polished several small areas within the valve cover. He told us that he
wanted to measure the accumulation of solids within these areas at the
planned 750,000 miles inspection. Well - at 761,000 miles Mr. Hill was
amazed to see that these areas were still clean and no measurable
buildup had taken place. the "end results" after 761,000 mile
inspection - All parts were reinstalled, the old oil was poured back in
and the truck went back to work!"
1,000,000 Mile Inspection:
Ask yourself this question - is it possible to run nine years,
1,000,000 miles and do it with just two unnecessary oil drains and
still have a good engine? Chances are you would answer the question
with a very unbelieving NO! For several years now there has been an
industry wide push for extended oil drains on trucks. Within most any
magazine to do with fleet maintenance you will find several oil
advertisements boasting about their 'NEW' oils. They all have claims of
achieving extended oil drain intervals, some up to 40,000 miles.
However, simply selecting a new type of oil and taking the 'Pour In &
Go' approach is not the single answer to extended oil drain intervals.
This 1990 Peterbilt achieved the 1,000,000 mile mark with only two oil
drains, not by the use of some new high teck oil, rather it was the
hard work of added filtration offered by the GCF paper towel bypass
filter. Added filtration is the key to extended oil drains.
At the 1,000,000 mile inspection, Howard Hill and Ricky Cook found
basically the same engine that they saw at 500k and 761k. The engine
was once again spotlessly clean and only marginal wear that could be
found was within the rings. Alongside our GCF equipped engine was
another engine that Covington Diesel was overhauling for another
customer. It was the same engine as ours and had 933,000 miles on it.
This engine was in normal 'good' condition for a Detroit with this
amount of miles. When we compared this engine to ours, one could
plainly see that our engine was much cleaner and had far less wear.
This other engine had routine oil drains every 12,000 miles. That's
over 77 oil drains in its life and this engine was undergoing a major
overhaul consisting of replacing all bearing, rings and liners. After
inspecting our engine, Howard and Ricky recommended that a set of
rings, not rings and liners, just rings, be replaced, The GCF equipped
engine, with only 2 unnecessary oil drains in 1,000,000 miles simply
needed rings. After determing the engine could be reassembled with only
the rings being replaced, we asked Mr. Cook to replace any two cylinder
kits, two rod and two main bearings. This would allow us to show parts
that had run a million miles using GCFs simple PM program. After the
work was complete, we once again poured the old oil back in and the
truck is now pulling for the 1 1/2 million mile mark. Gulf Coast
Filters, with the help of Shell Oil and Covington Detroit Diesel, have
proved conclusively that the use of GCF filters greatly extended oil
drains is now FACT not fiction!"
UPDATE: North Caroline Department of Transportation converting their
heavy equipment to GCFs. For the past three years the State of North
Carolina has been converting DOT equipment to GCFs. All 26 ferries
utilize the GCF filters. WE have delivered 194 GCF bypass oil filters
to NAVISTAR's factory for installation on new International trucks
ordered by NC DOT."
ANSWER: Your best bet would be to contact the factory. They have the oil
analyzed on the Detroit about every 10,000 miles. They have oil
analysis reports on everything from military equipment, offshore rigs,
shrimp boats, tug boats and even a race car. It's a matter of getting
all your ducks in a row. It's a matter of keeping the oil clean and
free of water and adding enough new oil to keep the additives up. As
you know any good motor oil has additives to neutralize acid and acid
can't form without water. I had to change the oil on my Subaru because
of oxidation at 83,000. I didn't have all my ducks in a row. I didn't
change the filter enough and I was running an extremely high oil
temperature. It has 220,000 on it now and has had four oil drains. I
was changing the bypass filter every 12,000 and adding a new qt of oil.
I should have been changing the bypass filter every 4,000 and adding a
new qt of oil. How much new oil you add is very important.
The oil the Detroit uses is Shell Rotella T 15-40. Lab analysis
always shows (SAE grade 100 degree C 40). The owner of the truck was
noticing he had to change the 2 rolls of Bounty big roll paper towels
more often lately to keep the soot content down. When the engine was
torn down for its million mile inspection the Detroit mechanic found
the problem. The line between the turbo and intercooler was split open
causing a rich mixture. What we do is put some oil on our skin. If it
doesn't wipe off clean we know it has too much soot in it. It's what we
call the palm test. When you change the big 0-2 Gulf Coast filter you
have to add 3 gallons of new oil. the little 0-1 jr takes one quart.
I don't know any of the bypass depth filters that can remove all of
the diesel soot. Some of it is large enough to cause wear and be
removed. Some of it is too small to cause wear or be filter out. We are
dealing with under 1/10th of one micron. My 84 6.9 Ford diesel probably
generates more soot than the Detroit. A new power stroke Ford doens't
generate much soot. Soot was a problem on the old gasoline engines but
hasn't been a problem on the newer gasoline engines. Motor oil can be
very dirty and still look clean because only soot turns oil black. A
lot of people are looking at their dipstick and saying my oil is clean
- yea right.
Good hearing from you. Tell the factory to fax or send you an oil
analysis report. Mine only goes up to 800,000. Put this in your file
