CJ-4 Diesel Oil for the 2007+ models with
Diesel Particulate Filters


Whether you manage a small to large vehicle fleet, or drive your own personal diesel, we've got the secrets to the longest life and lowest maintenance costs using the best synthetic oils and greases, nanofiber filtration, bypass filters and oil sampling analysis.  And in today's tough economic climate, most fleet managers are realizing they need to find smarter ways to reduce fleet maintenance costs while boosting fuel economy and extending their fleet's service life.  And it's not just the engine, but the transmission, differentials, transfer cases, ball-joints, power steering, and aux hydraulic systems.  You've come to the right place, because we've got the answers you need that few know. 

A million mile 5.7L gas-engine van with the original untouched transmission?  No, we're not kidding. If our technology can do that, imagine what we can do for your diesel and gas powered fleet.

Have you ever realized that not a single OEM publishes a performance spec for oil or air filters?  Do you know why?  Until now you've been held hostage to the profit agendas of the world's biggest companies.  But not anymore.  We're automotive engineers who are passionate about moving you past the marketing hype and big corporate agendas. We'll give you the real facts backed by test-data, and let you in on the very secrets that the OEM's, upfitters and big-oil (including the API) don't want you to know. 

How good are AMSOIL's synthetic oil and nanofiber filter technologies?
  The certified ASTM & SAE data shows that they reduce wear by 70 to 98% over the typical commercial fleet products that you're probably buying now.  That's why the OEM's remain silent and pretend to yawn, instead of telling everyone or writing high-performance specifications.  You deserve to know the facts, because these technologies have clear potential to double your fleet life.  What would that do for your business and survival strategy over the next three years?

Warranty concerns?  OEM's rely on your fear to boost their profits from your wallet, but don't be a victim of fear and myths.  OEM's cannot and do not deny warranties for using dramatically superior technology that outclasses mousey API/SAE service grade requirements and has nothing to do with their equipment failure.  A Dealer employee may occasionally try to verbally deny a warranty, but the OEM's don't because they have the legal burden of proof (not you) and they have to do it in writing.  Regardless, we stand with you on any issue.

Cold-Air Intakes for Better Performance & Profitability


Have you ever considered an aftermarket cold-air intake system for your 3/4 and 1-ton trucks, to increase power, fuel economy and towing performance? 


Does it have to be tough and durable?  Easy, low-cost maintenance?  More air-flow than your engine will ever need... but none of the dirt?


Yeh, that's what we thought, too.  So we've married highest-performance, lowest-maintenance-cost nano-fiber air filters with ultimate performance Power Flow air-intake systems from Injen Technology.  They're custom-designed to squeeze every advantage out of our 2 micron Absolute Efficiency nanofiber filters, and squeeze every available air molecule into your turbo-diesel engine, for an air intake system that defines high performance. 


    GM, Dodge & Ford diesel intakes are Here!




Guardian Pest Control Fleet Study


Gasoline Engine Case Study:

Read how the Guardian Pest Control fleet dramatically boosted their fleet performance, service life, and profits...  Some excerpts:


"It is incredible that the fleet has quadrupled in size and Guardian has not had to add an additional mechanic."

"The accompanying photos detail the condition of the 225,000 mile engine at the teardown."

"The rear main bearing cap and oil seal were in good condition. The rear seal was very pliable and still intact, showing no signs of deterioration."




Synthetic Diesel Oils:

Learn about the Performance Power and Financial Advantages of Synthetic Diesel Oil in Diesel Fleets and Diesel-Powered Equipment...    Some excerpts:

“In the trucking industry,” said Foster, “synthetic lubricants are commonly used in the drivetrain for fuel economy benefits. Yet, I found it hard to believe that changing the engine oil would help fuel economy. However, the data indicates about a three percent fuel economy increase, and we’ve certainly noticed a difference.” 
      — D.W., Arizona, Fire District Chief Mechanic

“AMSOIL HDD made a significant difference in my fuel economy.  I’ve compared the same period this year to a year ago — same time of year, same loads, same routes — and found a 12 to 34 mpg increase with HDD. For me, that translates into a $1,500 to $2,500 a year savings.”   
   — J.P., North Dakota, Independent owner/operator

"The test fleets include 45 vehicles equipped with Detroit Diesel 6V-92TTA engines with an average 350,000 test miles per vehicle; 10 vehicles equipped with Cummins NTC-350 engines with 220,000 test miles per vehicle; 21 vehicles equipped with Caterpillar 3406 DITA engines with 220,000 test miles per vehicle. All results shown are averages..."



Do YOU know the profit-power of Oil Sampling and Bypass Filtration??



Bypass Oil Filtration Means Diesel Soot Removal:

Deep-Cleaned Oil and Doubled Engine Life


BMK-17 Dual Remote Bypass Filter system installed on 2002 GMC Sierra with Duramax Diesel engine and Allison transmission.Our Bypass Filter systems for commercial and fleet applications in cars and light, medium and heavy trucks (to Class 8) can filter particles down to less than one micron and are 89% efficient at 1 micron, making oil changes virtually unnecessary and virtually eliminating engine wear.  (A standard full-flow oil filter can only filter to 20 microns with reasonable efficiency.) By removing all wear particles and extending oil life, these filters commonly increase fleet vehicle engine life by 30 to 100%. These are the highest performance oil filtration systems available on the market, and with easy-installation kits selling for only $175-$450, pay-back is quick.

New to Oil Sampling Analysis and Bypass Filtration?? 


Have you heard?  Those are the secrets that the most profitable fleets and equipment garages have used for decades: bypass filtration doubles their fleet life, and OIL ANALYSIS is their key to using high-performance true synthetic lubricants to optimally tune their maintenance program for low costs, high uptime, and effective Predictive Maintenance.  Isn't it about time YOU learned those secrets to become more profitable?

So Easy to Add Bypass Filtration to Your Engine



Biodiesel fuels strongly accelerate the breakdown of ANY engine oil. 
No matter what brand or type of engine oil you use, you will need to closely monitor your oil performance with oil analysis and shorten drain intervals as your use of biodiesel blends increases.  In many cases, this can mean cutting your previous oil drain intervals in half (assuming use of the same engine oil).  If extended oil drain intervals are not shortened, biodiesel contamination could produce engine damage due to oil failure.  [MORE]

AMSOIL is the undisputed leader in synthetics.............

Since 1972, AMSOIL Synthetic drivetrain LUBRICANTS have proven to be the highest performance engine oils, greases, transmission fluids, and hydraulic and differential gear oils on the market. 
But the other key issue is
nanofiber filtration. 
We now cover oil filters, air filters and other fluid filters like NO-ONE else can.  AMSOIL offers the highest performance, most cost-effective, most comprehensive filter line on earth.  Consider air and oil...


Until now, Nanofiber filtration technology has been used exclusively in heavy duty applications, including the US ARMY Abrams M1 tank. AMSOIL Ea Filters are the first and only filter line to bring this technology to the auto/light truck market.

EaO nanofiber oil filters provide unmatched full-flow filtering efficiency to 98.7 percent at 15 microns, and 50 percent at 7 microns.  This translates to a 70% reduction in engine wear rates, tripling remaining engine life while giving longer filter life and lower pressure drop for better cold-start performance: the only filtration that gives you the best performance in every category!  Compare that to the filters lining the auto-parts shelves, which don't tell you their common 7,500 mile design life and either won't tell you what micron level their efficiency rating is for, or they claim a micron particle size without stating an efficiency: deceptive, meaningless numbers. 

Additionally, consider bypass filtration systems for commercial and fleet applications in cars and light, medium and heavy trucks which can filter particles down to less than one micron and are 89% efficient at 1 micron, making oil changes virtually unnecessary and virtually eliminating engine wear.  (A standard full-flow oil filter can only filter to 20 microns with any reasonable efficiency, but 5-25 microns is widely accepted as the wear-particle size range.)  Easy to install, these oil filter systems have been proven by millions of miles of over-the road trucks, construction equipment and fleet service. And we use these on our personal diesel pickup trucks: my Duramax 2500HD has over 70,000 miles since the last oil drain, the oil analysis looks perfect, and the appearance of this diesel oil looks like a gas engine with 3,000 miles on the oil.

AIR FILTERS:Abrams M1A1 Battle Tank bites the dust with Nanofiber Filtration Technology

The MOST IMPORTANT filter on the M1A1 Abrams battle tank is its' nanofiber air filter. 
The MOST Important filter on YOUR vehicle is also the air filter.

It's far better, and easier, to keep wear particles out of the engine than it is to attempt filtering them out of the engine oil.  Yet filter companies and vehicle manufacturer's are strangely silent about actual air filter performance and engine needs.  Now AMSOIL offers world-leading breakthrough Ea air filters with exclusive nanofiber technology.  Based on battlefield-proven air-induction systems used in military ground and air vehicles, this high-technology filtration is now available for consumer use!  Ea filters are guaranteed for 4 years, 100,000 miles.  The engineering rule of thumb for damaging wear particle size is 5 to 25 microns.  Incredibly, these filters are 100% efficient at removing particles of 3 microns, and are 80% effective at removing particles of a 1 micron size.  This means that NO WEAR PARTICLES CAN GET PAST OUR Ea AIR FILTERS!  AND, they're less expensive to use than ANY other air filter.

For Power Sports applications, AMSOIL offers a line of oiled-foam filters.  These filters provide better performance than oiled-gauze air filters, and are used almost exclusively in most off-road applications including baja, dirt-track racing, and motocross.

For light to heavy trucks, both gas and diesel engines, AMSOIL's partnership with Donaldson provides you with the best performance and most cost-effective air filtration systems in the world.  These include both Powercore and Nanofiber technology filters.  We have the full line of  Donaldson Filters Now Available , including air, fuel, water, oil and hydraulic filters, with exclusive performance warranties (no one else in the industry offers filtration performance warranties).  Contact us for specific recommendations, or see our Diesel Page.

Air Induction Systems:

Well-engineered aftermarket air induction systems can provide airflow improvements with gains in horsepower, fuel economy, and towing torque.  Unfortunately in many cases they may also let far more wear particles into your engine than the OEM filter.  And oiled media can contaminate mass flow air sensors, causing problems with emissions, fuel economy and performance that can even damage transmissions in some cases.  AMSOIL lets you leave those problems behind. Their full line of nanofiber universal air induction filters (EaAU) are designed to replace stock oil wetted gauze or foam conical filters that were supplied with custom induction systems produced by K&N, Injen, S&B, Green, AIRAID, AFE, TrueFlow and more. Whether your air induction system is in a gasoline street-rod, or a diesel truck, you have great airflow but you need better filtration and more capacity than oiled gauze or foam.  AMSOIL Ea Air Induction Filters are dry no-oil filters with nanofiber filtration media to bring your aftermarket far better efficiency, 50 times the capacity, and excellent airflow while being easily cleanable - every 25,000 miles.
