How to order Amsoil


Dodge Cummins Turbo Diesel Amsoil 5w 30 is the best

You've spent your hard earned money on the Dodge Cummins Turbo 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 you have to use their brand of oil to "maintain your warranty". That is a false statement. We often 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 than AMSOIL 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 in the frequently asked questions 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 that if 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. 


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 Dodge Cummins Turbo Diesel plus save time and money. The Dodge Cummins Turbo Diesel is an excellent vehicle and exceptionally well engineered by Daimler-Chrysler and Cummins. 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. 

Specifically for the Dodge Cummins Turbo Diesel

  Specifically for the Dodge CumminsTurbo 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.

For 2007 and newer Dodge Cummins with Diesel Particulate Filters AMSOIL offers a 5W-40 Premium Protection Oil that is engineered to be changed as per manufactuer's recommendations, or longer with oil analysis testing. (Average 10 to 20K)


Another option is to install an AMSOIL Dual Remote By-Pass Filtration System. (see the BMK-25) With this system you only change your oil when oil analysis indicates. The regular full flow filter is changed at 25,000 mile/1-year intervals and the by-pass filter is changed at 25,000 miles/1-year. 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 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 Dodge Cummins Turbo Diesels and can provide you with exact installation instructions, tips, bracket prints and photographs of our company truck.

We have many customers with years of service and tens of thousands of miles on their Dodge Cummins Turbo Diesels with no oil changes. Laboratory oil chemical analysis approximately every 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. 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.
