Duramax Trucks: You've spent your hard earned money on the Duramax Diesel
option in one of the most popular and well 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 Duramax Diesel dealership service center tell you that you
have to use their brand of oil to "maintain your warranty". That is one of the biggest untruths we have heard,
yet it goes on day in and day out. We constantly receive calls from customers that were told this by their
servicing Duramax Diesel dealership. This practice is not authorized or condoned by the auto manufacturers, but the fact is it
still goes on.
How a servicing Duramax Diesel 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.
For the Duramax Diesel, AMSOIL engineers and manufactures a fuel efficient 5W-30 Synthetic Heavy Duty Diesel Oil
and a 15W-40 Synthetic Heavy Duty Diesel Oil that when used in conjunction with the AMSOIL Super Duty engine oil
filters will allow you to travel 7,500-10,000 miles between filter changes and 20,000 miles minimum 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 GM Specifications
The other option is to install an AMSOIL Dual Remote By-Pass Filtration System. With this Duramax Diesel system you only change
your oil when oil analysis indicates. The regular full flow filter is changed at 7,500-10,000 mile intervals and
the by-pass filter is changed at a minimum of 25,000 miles (or longer with oil analysis). The AMSOIL 15W-40
Synthetic Heavy Duty Oil does not break down like conventional petroleum based motor oils, is much more shear
stable and does not have the waxes, paraffins and by-products that come out of crude oil that is pumped from the
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 Duramax Diesels and can provide you with exact installation
instructions, tips, bracket prints and photographs of previous installations.
One of the Power Stroke Diesels in our dealer group has over 84,000 miles on the
same oil as of November 2003. 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. We will mail you a copy of this vehicle'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.
Duramax Diesel 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 Duramax Diesel 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 EaO Duramax Diesel engine oil filter utilizes a synthetic nanofiber 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 filtration
media that represents 98.7% efficiency at 15 micron and is 50% efficiency at 7 micron absolute. The Amsoil
EaO oil filter yields 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 Duramax Dual Remote by-pass filtration system then the AMSOIL EoA full flow
engine filter would be of a significant benefit to the long term durability of your engine as well as allowing
for 15,000 to 25,000 miles of service on the filter.
AMSOIL has a complete line of synthetic motor oils, greases, transmission fluids, gear lubes, Two-Stage foam air
filters, by-pass and full flow filters and filtration systems designed to extend the life of your Duramax
equipment and save you time and money. In addition we also offer a Preferred Customer wholesale 25% - 30%
wholesale purchase option,
retail purchase option or commercial wholesale account purchase option for businesses. We also offer a Dealership Option
for anyone interested in becoming an AMSOIL Dealer and/or purchasing products at wholesale cost.
"How to Reduce or Prevent Turbocharger Bearing
Seizures" on Duramax Diesels
One of the many specific
areas, on turbocharged Duramax Diesel engines, that can clearly benefit from the use of synthetic oil is the
turbocharger. When a turbocharged engine is shut off immediately after use, "heat soak" occurs due to the
extremely high temperature still present in the turbocharger. Over a period of time this can lead to deposits
that can reduce or block the oil flow to the Duramax diesel turbocharger bearings which can lead to turbocharger bearing
AMSOIL's Synthetic Duramax Diesel Oils are inherently more thermally stable than many diesel oils on the market and have
been shown to keep turbochargers considerably cleaner than other brands of oil. While poor quality engine oils
have been shown to cause turbocharger bearing seizure in under 100 hours during a "heat soak" test.
Many engine oils will survive the 100 hour "heat soak" test, but..., with considerable deposits and incipient
oil passage blocking. If you use low quality diesel oils make sure you let the engine idle for a few minutes
after use to allow the engine and turbocharger to cool. This does not eliminate deposit formation but it can
Take a look at the varnish deposits in this picture. These are the results of a severe high temperature deposit
test. This test clearly shows that AMSOIL keeps engines cleaner longer than other major brands diesel oils.
Which oil would you rather have protecting your engine?
The bottom line: To prevent
or eliminate Duramax diesel turbocharger bearing seizure, there is no substitute for a high quality synthetic diesel oil (like AMSOIL's) as they have been have been proven to maintain turbochargers in an almost "as fitted" condition and
significantly reduce deposit formation.
We are here to help you learn the facts and show you how you can use
AMSOIL and get a superior product and also increase the performance and add to the longevity of your Duramax
Diesel plus save time and money. Duramax Diesel trucks are excellent vehicles and exceptionally well engineered
by General Motors. In our opinion they are one of the most advanced vehicles ever produced, however there are
ways to make the performance and longevity even better with AMSOIL Synthetic Lubricants.
We 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
Simply changing your Duramax Diesel oil more often with "reputable" 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.
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.

Learn About the Deficiencies of Today’s
Ultra Low Sulfur Diesel Fuel
and the Importance of Using AMSOIL's
Diesel Concentrate Performance Fuel Additive
Diesel Concentrate Performance Fuel Additive (ADF)
Total system cleaner and lubricity improver for all types of diesel engines.
Excellent for ultra low sulfur diesel and biodiesel fuel.
AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency. It compensates for the
variances in quality of different fuels (including biodiesel) and the deficiencies of today’s Ultra Low
Sulfur Diesel fuel (ULSD) for better engine operation. New engine technology, tighter tolerances and
emission regulations require high-quality diesel fuel for long-term engine operability. AMSOIL Diesel
Concentrate meets the low sulfur mandate. It improves diesel fuel quality to exceed today’s stringent
performance requirements. AMSOIL Diesel Concentrate extends equipment life, lowers operating costs and
improves diesel performance.
Improves Fuel Economy and Restores Horsepower
As diesel engines are used, they become less efficient over time. Fuel injector deposits interrupt spray
patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. Tests
prove that AMSOIL Diesel Concentrate cleans dirty injectors, improving fuel economy by up to five
percent and restoring horsepower to like new. Acceleration is improved and with regular use, AMSOIL
Diesel Concentrate continues to enhance performance by keeping injectors clean. The net savings on fuel
expense can result in no additional cost to vehicle operation.
Lubricates Fuel Pump and Injectors
Ultra low sulfur diesel fuel has significantly reduced lubricity – a critical property in controlling
wear in fuel pumps and injectors. AMSOIL Diesel Concentrate adds back all the lubricity properties
needed and more. Fuel pump and injector service life is extended, saving time and money on maintenance
Reduces Cylinder Wear, Retains Engine Oil TBN Longer
With high rates of exhaust gas recirculation (EGR) in modern diesel engines, acids from combustion are
of particular concern. AMSOIL Diesel Concentrate neutralizes acids during combustion. It helps reduce
acid caused cylinder wear and helps extend engine oil TBN, maintaining engine oil quality longer for
Minimizes Soot Loading
AMSOIL Diesel Concentrate is a powerful cleaner that cleans fuel injectors and piston rings for improved
combustion and better sealing. It minimizes soot generated from incomplete combustion and helps keep
soot out of the crankcase. Reduced soot loading controls soot related wear and engine oil viscosity
Fuel degradation can cause gums, which increase deposits and the chance of filter plugging. AMSOIL
Diesel Concentrate significantly improves the oxidation and thermal stability of diesel fuel. It
overcompensates for ultra low sulfur diesel fuel’s potential stability loss caused by extra processing
and sulfur removal. Diesel fuel treated with AMSOIL Diesel Concentrate easily meets the requirements of
the National Council of Weights and Measures (NCWM) Premium Diesel Fuel Specification for resisting
diesel fuel degradation.
Improves Water Tolerance
AMSOIL Diesel Concentrate is an alcohol-free product that protects fuel systems against water
contamination. It helps prevent fuel/water emulsions and it protects metal against rust. Water can be
drained easier and fuel filters are less likely to plug, ensuring drivability.
Heating Oil Improver
AMSOIL Diesel Concentrate provides many of the same benefits in heating oil furnace applications. It
provides fuel oil storage stability, water stability, rust protection, fuel oil filter longevity, and in
certain applications, can keep fuel oil nozzles clean for proper spray in the combustion chamber. AMSOIL
Diesel Concentrate promotes trouble-free operation. AMSOIL Cold Flow Improver is recommended where fuel
oil is stored outside.
AMSOIL Diesel Concentrate is recommended for use with all types of heavy- and light-duty, on- or
off-road and marine diesel engines. Recommended mix ratio is one oz. of additive per five gallons of
fuel. Use with every new tank of fuel for the best performance and protection against fuel pump wear,
injector wear and injector deposits. Compatible with all types of exhaust emission systems such as
diesel particulate filters (DPFs). Add Diesel Concentrate to fuel before storage. Excellent for use with
AMSOIL Cetane Boost and AMSOIL Cold Flow Improver. This diesel fuel additive complies with the federal
low sulfur content requirements for use in diesel motor vehicles and non-road engines.
