- Amsoil Products for Ford Powerstroke Diesel Trucks
The 6.0L Power Stroke uses a canister element oil filter on top of the engine. The AMSOIL Absolute Efficiency Synthetic Oil Filter for the 6.0 PSD is Part #EAO-88. The 1994-2003 7.3L Power Stroke Oil Filter Part # is EAO-99. and have a change interval specification of 25,000-miles/1-year. No other company has an oil filter that has these specifications except AMSOIL. When using the AMSOIL 15W-40 Synthetic Heavy Duty Diesel oil or the Series 3000 5W-30 Heavy Duty Diesel oil, the oil filter element must be changed at 25,000-miles/1-year. The specification on the oil is 25,000-miles/1-year, or longer with oil analysis testing.
You've spent your hard
earned money on the Ford Powerstroke Diesel option in one of the most popular and best engineered trucks
there is, now don't you think you owe it to yourself to use the very best oil in it? And don't let your
local dealership service center tell you that you have to use their brand of oil to "maintain your warranty". That
is a 100% false statement by the dealership, yet it goes on day in and day out. We constantly receive calls
from customers that were told this by their servicing dealership. This practice is not authorized or
condoned by the auto manufacturers, but the fact is it still goes on.
How a servicing dealership can essentially tell a customer that they have to use a lower
quality oil to "maintain their warranty" is not only wrong but it is also illegal unless they provide it free of
charge. There are Federal laws that protect you against this. Please read our Warranty Laws You Need to
Know section of this website to learn more.
In a recent Lubricants World Magazine interview the president of a
major national quick lube chain (which is owned by a major petroleum oil company) states thatif they can get customers to shorten their
drain intervals by 100 miles it would mean an additional $20 million in revenue for the company per year and if
they can get consumers to do one more oil change per year it would mean $294 million for the oil change alone and
$441 million in revenue when they include ancillary products and services that go along with the oil
change. In fact, the president of the quick lube chain openly admits that the bottom line is profits.
The shorter the drain interval the more money the quick lube makes. It is our opinion that they would be more
profitable by promoting and installing AMSOIL extended drain interval synthetic motor oil. It appears
that the short drain interval petroleum oils they promote are good at assuring that customers will be back for
another oil change in a relatively short period of time.

Take a look at the varnish deposits
in this picture. These are the results of a severe high temperature deposit test. The one at the far right is
AMSOIL Synthetic 15W-40 Diesel Oil and the others are major brand petroleum diesel oils. (left to
right: Chevron Delo 400, Cummins Premium Blue, Shell Rotella T, AMSOIL (15W-40). The test clearly shows that
AMSOIL keeps engines cleaner longer than other major brand diesel oils do. Which oil would you rather have
protecting your engine?
We are here to help you learn the facts and show you how you can use
AMSOIL motor oil and get a
superior product and also increase the performance and add to the longevity of your Ford Powerstroke
Diesel plus save time and money. The Powerstroke Diesel is an excellent vehicle and exceptionally well
engineered by Ford Motor Company and International. In our opinion it is one of the best vehicles ever
produced, however there are ways to make the performance and longevity even better with AMSOIL Synthetic
Lubricants.
Synthetic Oil Proven to Prevent Turbocharger Bearing Seizure
One
of the many specific areas on a turbocharged engine, such as the Powerstroke Diesel which can clearly benefit
from the use of synthetic motor oil is the turbocharger. When a turbocharged engine is shut off immediately
after a high speed run, "heat soak" occurs from the engine, and it considerably increases the temperature in the
turbocharger. Over a period of time this can lead to deposits that can block the oil flow to the turbocharger
bearings, leading to turbocharger seizure. Synthetic engine oils that are inherently more thermally stable
than petroleum engine oils have been shown to keep turbochargers considerably cleaner than petroleum engine
oils. A poor petroleum oil will give turbocharger seizure, caused by blocked oil ways, in under 100 hours of
a severe "heat soak" test cycle. A good petroleum oil will survive for 100 hours but with considerable
deposits and incipient blocking. A good synthetic oil will maintain the turbocharger in almost "as fitted"
condition. Read on to learn the many more ways in which your Powerstroke Diesel/ Ford Diesel can
benefit from synthetic oil.
Current recommended practice is to change your oil every 3000-5000 miles with petroleum based
oil as well as with some other brands of synthetic oils. This is completely unnecessary with the AMSOIL technology
that is available today, and has been available since 1972. The auto companies all know about AMSOIL but do
not promote it because it is often perceived that it can potentially cause them lost profits in service work,
parts sales, quick lube oil changes and on a long term basis, regular repeat vehicle sales since engines,
transmissions and differentials have been proven to last longer with AMSOIL Synthetic Lubricants. Several
dealerships we have visited stated that they like to keep customers coming in every 3000 miles so they can look the
vehicle over and possibly find other components that they can service.
The "3000 mile oil change" is, in our opinion, completely unnecessary. Many of
the same companies that continue to recommend the "3000 mile oil change" in the U.S. currently manufacture
and/or recommend, and have for many years, 12,000-18,000 mile synthetic oil changes in Europe. In fact Europe's
goal is to reach 30,000 mile oil change intervals in the near future.
It is also our opinion that the people that run the quick lubes and service centers are
there to make profits by seeing you on a regular basis. We know this because we
have tried to get some of the quick lubes and dealership service centers to carry AMSOIL extended drain interval
gas engine oil (25,000 miles/1-year and 35,000 miles/1-year with the 0W-30) and get the standard response that they
know it is an excellent product but if they install it they cannot keep customers coming back as often. AMSOIL then
tailored a special top quality reduced mileage extended drain interval oil (called XL7500) of 7500 miles for
gas engine vehicles for the quick lubes so they can keep customers coming back but still give them added
convenience of extended drains intervals. This has proven to be an excellent program for all involved.
In addition, many auto and equipment companies have tested AMSOIL and know how good it is and
many OEM auto engineers we work with even use it in their own vehicles but we believe they will not use it in
production for "political reasons". In fact, we first learned about AMSOIL many years ago when it was determined
that a major OEM factory race team uses AMSOIL, yet advertises another manufacturers brand of oil under a
sponsorship program.
It is our opinion that oil companies need to sell large volumes of oil and auto companies
want your engine and powertrain to have somewhat of a finite life. Enough life so that you are a very satisfied and
happy customer and will come back and buy another one yet not so long that you won't need to buy another vehicle
for a long time. Petroleum oil appears to accomplish both objectives. For the last 31 years, AMSOIL has been
proven by hundreds of of millions of miles of over the road testing as well as industry standard laboratory ASTM
testing to allow vehicles and equipment to perform better and last longer than vehicles using petroleum
oil.
The fact is that if every vehicle in the U.S. used AMSOIL that oil usage and waste oil would
be reduced by over 80%! Just imagine the money saved and the positive environmental benefits, not to mention
the improved wear protection provided by AMSOIL synthetic lubricants. Plus the fuel savings alone would amount to
3.66 billion gallons of fuel yearly and this is based on 1998 data, the last year Domestic Fuel Consumption data is
available from the government. Now, with those hard facts in-hand I find it hard to believe the auto companies are
not taking action to go100% synthetic on all lubricants in production vehicles.
I have an article of an AMSOIL user with 731,000 miles on his 1993 Ford Aerostar on the
original engine and transmission. He was using AMSOIL from the beginning. This type of mileage is not uncommon
when using AMSOIL synthetic lubricants. Now, what do you think would happen it everybody used AMSOIL and got
that much mileage on their vehicles? The auto companies like to hear reports of stuff like this on a small time
basis but not on a large scale as it could have major negative economic implications.
Nobody in the business of selling 3000 mile petroleum oil changes and repairing vehicles
is going to tell you how to extend your drain intervals using AMSOIL technology and drastically reduce the rate of
internal wear and they know very little, if anything, about the technical and engineering aspects of lubrication,
filtration and oil analysis science.
Simply changing your oil more often with petroleum oil will not give you all the benefits
that AMSOIL offers: You will not get improved fuel economy, you will not get
reduced engine wear, you will not get reduced operating temperatures, you will not get extended drain intervals and
you will not save money in the long run. Please, allow us to show you a better
way. We are here to help you. You have everything to gain and absolutely nothing to
lose.
AMSOIL has been in business
since 1972 and was the first company in the world to develop an API (Automotive Petroleum Institute) rated
synthetic lubricant for automotive applications. They coined the phrase "extended drain intervals" 30 years
ago and have been on the leading edge of technology and innovation ever since then. We have many satisfied
customers using AMSOIL products in both their commercial, trucking, fleet as well as personal, family and
recreational vehicles. We hope you will allow us to show
you a proven better way. We are here to help you and are at your service to assist you in your advanced
technology lubrication and filtration needs.
Specifically for the
Ford Powerstroke Diesel AMSOIL engineers and manufactures a AMSOIL Synthetic 15W-40 Diesel Oil
(as well as Series 3000 5W-30
Heavy Duty Diesel Synthetic Oil) that when used in conjunction with the AMSOIL Nanofiber
Technology EAO-99 engine oil
filter (7.3L) will allow you to travel 15,000 miles between filter changes and approximately 20,000
miles between oil changes. This was established by oil analysis testing. If you use oil analysis you can
usually go longer than 20,000 miles. Other AMSOIL benefits include reduced sludge and deposit formation,
extreme temperature protection, improved fuel efficiency and rust and corrosion prevention and it does not void any
new vehicle warranty. AMSOIL Synthetic Lubricants meet and exceed all API rated and
Ford specifications.
The other option is to install an AMSOIL Dual Remote By-Pass Filtration System. With
this system you only change your oil when oil analysis indicates. The regular full flow filter is changed at
7,000 mile intervals and the by-pass filter is changed at approximately 20,000 miles (or longer with oil
analysis). The AMSOIL AMSOIL Synthetic 15W-40 Diesel Oil does not break down like conventional petroleum based
motor oils, is much more shear stable and does not have the waxes, paraffin's and by-products that come out of
crude oil that is pumped from the earth.
The
by-pass filter removes the particles that cause wear in your engine down to less than one micron (a micron equals
0.001 mm) and keeps the engine oil analytically clean so you do not need to change your oil for a long time, while
still getting far better protection than someone that changes their oil every 3000 miles. We are experienced at
installing these units on Powerstroke Diesels and can provide you with exact installation instructions, tips,
bracket prints and photographs of our company truck.

AMSOIL Introduces World’s First Oil Filter Cartridge for Diesel Applications
with Nanofiber Technology.

AMSOIL INC. of Superior, WI has introduced a new premium, high efficiency cartridge oil
filter utilizing nanofiber technology for Ford 6.0L diesel engines. The new EaO-88 is the
world’s first oil filter cartridge for diesel applications using advanced submicron full
synthetic media. The EaO-88 provides an efficiency of 98.7% at 16 microns, significantly higher
than the OEM filter.
The rigid construction of this filter is due to a polymeric center tube and end caps, along
with its proprietary composition incorporating special grade nanofiber synthetic media,
enabling the filter to last up to 1 year or 25,000 miles when used in conjunction with AMSOIL
synthetic motor oil. Because of its improved oil flow, an additional benefit of this synthetic
filter media is that oil is delivered to key engine components quicker, thus enhancing the
lubrication process during cold weather starts.
Benefits include:
- Superior filtration efficiency
- Excellent flow characteristics
- Reduced engine wear
- Rugged and durable design
Fast Fact: A nanofiber is less than one micron in diameter. A human hair is
80 microns.

For example, the Performance Oil Technology Powerstroke Diesel vehicle #3 has over
85,000 miles on the same oil. Laboratory oil chemical analysis every 15-20,000 miles indicates the
oil is perfectly suitable for continued service. Other customers have traveled well over 100,000 miles and oil
analysis still indicates no oil change necessary. I will mail you a copy of vehicle #3's oil analysis results
with your product and technical information package so you can see the data for yourself. In addition, the
AMSOIL By-Pass filter will also remove up to a pint of water from your
vehicle's lubrication system, which is especially important in a diesel engine. Without this the water
promotes rust, corrosion and rapid wear. Internal engine heat also creates acids which also wear the engine
components. The water and acids build and continue to work destroying your engine even after engine
shutdown.
Oil analysis provides a
big return for your small investment by extending equipment life by preventing premature component failure,
reducing maintenance costs by eliminating unnecessary component changes and a decrease in downtime due to premature
scheduled maintenance as well enabling calculation of optimum drain intervals that will reduce lubricant costs and
assure maximum equipment protection.
Your regular full flow engine oil
filter will only remove wear particles down to the 20-25 micron range. The filter cannot remove finer
particles because the oil must be filtered quickly while removing most of the particles present in the oil, except
the particles below the 20 micron range. A study completed by Federal Mogul Corp. analyzing over 7000 main
and connecting rod bearings concluded that 60% of all engine wear occurs in the 5-20 micron range. This is
why no matter how much you change your current full flow oil and filter, regardless of brand, that you still are
not removing the particles that cause the greatest wear in your engine.
The AMSOIL
Super Duty engine oil filter utilizes a depth-type lofted fiber media that traps and holds dirt throughout its
entire thickness whereas a regular folded paper surface-type filter quickly becomes restricted as debris builds up
on the paper surface. The AMSOIL full flow filter has a finer synthetic cellulose filtration media, 75%
greater efficiency and up to 300% greater capacity than other popular oil filters as tested according to the
Society of Automotive Engineers HS806 test method.
If you
choose not to install the Dual Remote by-pass filtration system then the AMSOIL Nano
Technology full flow engine filter would be of a significant benefit to the long
term durability of your engine as well as allowing for 7,000 miles of service on the filter. When the
filter is changed at 7,000 miles all you have to do is top off the oil. When you reach 20,000 miles you
can either change the oil and filter or take an oil sample from the dipstick tube using an AMSOIL sampling pump
and send it into Oil Analyzer's Inc. using a pre-paid kit. Oil analysis will indicate the exact condition
of the oil and whether it is suitable for continued service as well as determining if there are any other engine
components or wear items that you need to be concerned with.

AMSOIL FFK-60 Fuel Filter for Ford 6.0L Diesel
PowerStroke™ Applications
The AMSOIL FFK-60 Fuel Filter incorporates both a primary and secondary
filter for maximum fuel cleanliness. The primary 10 micron filter, located in the Horizontal Fuel Conditioning
Module (HFCM), performs initial fuel cleansing before sending the clean pressurized fuel to secondary four
micron filter, mounted to the oil filter housing.
The secondary fuel filter includes a fuel pressure regulator and an
orifice on top of the housing that bleeds air out of the housing and back to the fuel tank. Following its trip
through the secondary filter, fuel is returned to the HFCM, where it is either directed to the tank or returned to
the primary filter.
AMSOIL EAO-88 Oil Filter for Ford 6.0L Diesel
PowerStroke™ Applications
Constructed of a highly efficient synthetic blend media, the AMSOIL
EAO-88 Oil Filter provides increased engine life and improved filtration efficiency.
The AMOSIL EAO88 is a cartridge-style filter located on the top of the
engine. When the filter is removed during servicing, the oil filter housing drain valve automatically opens,
draining the oil from the housing to the pan.
The oil filter base of the EAO88 directs oil to the oil filter, engine
oil pressure switch (EOP), engine oil temperature sensor (EOT) and turbocharger oil feed. The filter base also
includes an anti-drain back check valve, keeping oil in the filter assembly when the engine is shut off.
