Chevrolet Duramax Diesel Owners 

The Durmaax Diesel is co-developed by GM and Isuzu. It is direct injected with a 17:1 compression ratio and a high pressure Bosch electronic common rail injection system with 32 valves and a wastegated turbo. The block is cast iron and the cylinder heads are aluminum, which promotes excellent heat transfer and weight savings. The Duramax engine has an excellent power to weight ratio and puts out over 300 Hp and 520 lb.-ft. torque.

AMSOIL offers superior lubrication technology for your Duramax Diesel engine. Learn what many manufacturers and servicing dealerships don't want you to know about AMSOIL synthetic motor oil from experienced Truck Engineers and Lubrication Specialists right here in the auto and truck engineering and manufacturing capital of the world- Detroit, Michigan.

We are diesel engine, powertrain and chassis experts and are here to help you achieve optimum performance and longevity from your truck.

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 dealership service center tell you that you 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.

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 Duramax Diesel plus save time and money. The Duramax Diesel is an excellent vehicle and exceptionally well engineered by GM and Isuzu, however there are ways to make the performance and longevity even better with AMSOIL Synthetic Lubricants.

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?

Synthetic Oil Proven to Prevent Turbocharger Bearing Seizure

One of the many specific areas on a turbocharged engine, such as the Duramax 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 oilways, 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 Diesel Duramax can benefit from synthetic oil.

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 Duramax Diesel AMSOIL engineers and manufactures a 15W-40 Synthetic Heavy Duty Diesel Oil (as well as Series 3000 5W-30 Heavy Duty Diesel Synthetic) that when used in conjunction with the AMSOIL Eao-52 engine oil filter will allow you to travel 25,000 miles/1-year between filter changes and 25,000 miles/1-year between oil changes for normal duty service  If you use oil analysis you can usually go longer than 25,000 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 system you only change your oil when oil analysis indicates.  The AMSOIL Ea full flow filter is changed at 25,000 mile intervals and the by-pass filter is changed at approximately 25,000 miles for normal duty service.   The AMSOIL 15W-40 Synthetic Heavy Duty Oil  or the Series 3000 5W-30 HDD 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 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 and can provide you with exact installation instructions, tips, bracket prints and photographs.

The Performance Oil Technology Powerstroke Diesel vehicle #3 had over 87,000 miles on the same AMSOIL 15W-40 Synthetic Diesel Oil prior to changing to the AMSOIL Series 3000 5W-30 Heavy Duty Diesel 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 average 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.

If you choose not to install the Dual Remote by-pass filtration system then the AMSOIL Ea Oil Filter would be of a significant benefit to the long term durability of your engine as well as allowing for 25,000 miles of service on the filter and 25,000 miles/1-year on the oil.

Ea Oil Filters feature advanced full synthetic nanofiber technology, making them the highest efficiency filters that are available for the auto/light truck market. They have an absolute efficiency rating of 98.7% at 15 microns and 50% at 7 microns.

When you reach 25,000 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 has a complete line of synthetic 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 vehicles and equipment and save you time and money.  In addition we also offer a preferred customer wholesale purchase option, retail purchase option or commercial 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.
