Your turbocharger needs a good synthetic oil for long life! 

"Aren't all Amsoil Dealers biased?" Some are. We are degreed engineers first, and we think you deserve a perspective on oils and filtration that's both highly qualified and objective, but we know that's tough to find. So after many years of automotive engineering experience we became AMSOIL dealers to help explain the facts and data, and move you past the marketing hype onto solid footing. We ARE biased in the sense that we want REAL data, REAL performance, and REAL value for our vehicles. So we sweep the hype off the table and look at certified scientific data so that our opinions and recommendations will have the best possible benefits.

 

One paperclip is usually as good as another, and when they aren't it doesn't matter. But in some fields, there is a world technology leader that brings stunning performance and great value to the table. In lubrication fluid and filtration performance, AMSOIL is that leader. We've seen it "up close and personal" in our own vehicles, and we know that when you understand the benefits of AMSOIL technologies, you'll see big benefits for your Dodge.

Specifically for the Dodge Cummins Turbo Diesel

AMSOIL engineers and manufactures a fuel efficient Series 3000 5W-30 Synthetic Heavy Duty Diesel Motor Oil, a 15W-40 Premium Heavy Duty Diesel & Marine oil, and a new 5W-40 Premium Synthetic Heavy Duty Diesel Motor Oil that exceeds the CJ-4 specification for the new 2007+ Cummins engines with Diesel Particulate Filters (DPF's).  (which oil should I use?)  When used in conjunction with the AMSOIL Ea nanofiber engine oil filters, the first two oils will allow you to travel 25,000 miles minimum between oil and filter changes. This has been firmly established by extensive oil analysis testing and millions of fleet miles. In fact, if you use oil analysis you can usually just change the filter and go much longer than 25,000 miles on the oil. 

However, the 5W-40 (DEO) is recommended for use at the longest Dodge/Cummins oil-drain interval listed in the manual.  Due to the lower TBN of the DEO's low ash CJ-4 formulation, longer drain intervals will require oil analysis sampling until more data can be collected on extended drain interval performance.  All of these oils deliver proven fuel economy gains.

AMSOIL benefits include reduced sludge and deposit formation, extreme temperature protection to extend your turbo life, improved fuel efficiency and rust and corrosion prevention - and of course it does not void any new vehicle warranty. AMSOIL Synthetic Lubricants meet and exceed all API and Dodge specifications.  In fact, these lubricants are so advanced that they've typically met/exceeded nearly every OEM manufacturer's published diesel oil test standard, worldwide, without any reformulation. 
 

The Secret Power of Nanofiber Bypass Filtration

The ULTIMATE oil-filtering option for lowest maintenance costs and downtime is to install an AMSOIL Dual Remote By-Pass Filtration System. This is the highest performance bypass oil filter in the world for light to heavy vehicle applications.  With this nanofiber technology system you only change your oil when oil analysis indicates a need. The full flow EaO filter is changed at 15,000 mile (severe service) or 25,000 mile (normal service) intervals and the EaBP Bypass filter is changed at a minimum of 60,000 miles/2 yrs (or longer with oil analysis).

For most gas or pre-2007 diesel vehicle applications, oil analysis will show that you NEVER need to change your oil again - even after 500,000 miles! 

How is this possible???  Simple: by using oil that is designed to not break down, and using filtration that removes all wear particles, there is no longer a need to change oil.  This saves a lot of downtime, as well as money, and uses about 80% less motor oil.

The AMSOIL 15W-40 Premium Heavy Duty Diesel & Marine oil and Series 3000 5W-30 Heavy Duty Diesel Motor Oil do not break down like conventional petroleum based motor oils, and they are much more shear-stable (maintaining viscosity).  Because they do not have the waxes, paraffins and by-products that come out of crude oil that is pumped from the earth, they do not build up internal engine deposits of tar, sludge, and varnish.  In fact, Amsoil oils continually clean the inside of your Cummins engine.  Which oil should I use?

The AMSOIL EaBP by-pass filters are nanofiber based, to remove the particles that cause wear in your engine down to less than one micron (a micron equals 0.001 mm) and keep 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. In fact, this level of filtration was determined in research, published in SAE Paper #881825, to reduce engine wear so much (way over 90%) that the wear rates could not be measured effectively.  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.

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 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 a high mileage Dodge Cummins Turbo oil analysis test results with your product and technical information package so you can see the data for yourself.

Oil analysis provides a big return for a small investment: it extends 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. Oil analysis is an easy, simple, quick procedure - but here's a short video to show you how easy it is:

  See this video on YouTube

A regular full flow engine oil filter will only remove wear particles down to the 20-25 micron range, while an AMSOIL full-flow EaO filter removes the majority of particles in the 7-20 micron range. But a full-flow filter simply cannot remove all the finer particles because the oil must be filtered quickly while removing most of the particles present in the oil.  That leaves some 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.

Extensive testing shows that AMSOIL Ea Oil Filters achieve a near-perfect absolute efficiency rating. The exclusive new technology used in AMSOIL EaO Filters provides filtering efficiency to 98.7 percent at 15 microns, and 50 percent at 7 microns. EaO Filters are the most efficient full-flow filters that are available for auto/light trucks, period.

Q: How do EaO filters compare to the full-flow SDF filters that AMSOIL offered for many years?
A: AMSOIL SDF Filters are not quite as efficient as an EaO: filtering efficiency was 94.3 percent at 15 microns and 51.2 percent at 7 microns. The AMSOIL SDF full flow filters had 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 (SAE) HS806 test method. The new Ea filters, with nanofiber technology, are even better.

Now consider the new nanofiber bypass filters, which are used in addition to a full-flow filter.  AMSOIL EaBP Filters are high efficiency bypass filters with 98.7% efficiency at two microns. They also remove soot, providing the ultimate in protection against wear, oil degradation and corrosion: your diesel's dipstick will show remarkably clean oil, slightly darker than from a gasoline engine.  Most importantly, you virtually eliminate engine wear, because the wear particles are filtered out of the oil. 

A complete BMK-15Ea AMSOIL Dual Remote By-Pass Filtration System kit for the Cummins costs about $300 or less (depending on options), so it is a cost-effective improvement that will pay for itself quickly: just add up the cost of your standard oil changes and instead substitute about $60-70/yr for a filter, oil, and oil sample analysis.

If you choose not to install the Dual Remote by-pass filtration system, the AMSOIL Ea full flow engine filter allows for 25,000 mile filter change intervals, and the 70% nanofiber wear-rate reduction is still a strong benefit to the long term durability of your engine - multiplying your remaining engine life by roughly 3 times (assuming only mild or no power upgrades). When you check your oil level every 5,000 miles or 3 months, all you have to do is top off the oil. When you reach 25,000 miles/1-year 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.

When using AMSOIL nanofiber Ea Air and Oil filters, analysis will usually allow extending AMSOIL drain intervals far beyond the guaranteed 15,000 (Severe) or 25,000 mile (Normal Service) drain intervals.

For most gas or pre-2007 diesel vehicle applications using AMSOIL synthetics and nanofiber bypass filtration, oil analysis will show that you NEVER need to change your oil again - even after 500,000 miles! 

How is this possible???  Simple: by using oil that is designed to not break down, and using nanofiber filtration that removes all wear particles, there is no longer a need to change oil.  The oil is so tough that just topping off the oil level when changing filters is enough to renew the additive package.  This saves a lot of downtime, as well as money, and uses about 80% less motor oil - which benefits both your wallet and the environment.

AMSOIL has a complete line of synthetic oils, greases, transmission fluids, gear lubes, Ea nanofiber 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.

Maintaining Your Warranty

Don't let your local dealership service center tell you that you you have to use their brand of oil, or you can't use a synthetic 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 dealership. Please be aware that this practice is not authorized or condoned by the auto manufacturers.

For a servicing dealership to essentially tell a customer that they have to use a lower quality oil to "maintain their warranty" is not only wrong and illogical - 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, and our section on API Licensed oils to learn more.

Another blatant public scam is the idea that you MUST change your oil every 3,000 or 5,000 miles or you are being an irresponsible vehicle owner. The State of California and GM are so fed up with this that they have started an educational program to teach drivers to change oil less frequently.  Why are people told this 3,000 mile baloney so often?

The people that run the quick lubes and service centers are there to make profits by seeing you on a regular basis.  They do not care about protecting the environment from excessive oil usage any more than they care about the Golden Rule or extending your vehicles' life. 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). Sometimes they get the big picture and start offering Amsoil.  But typically we 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 companies have tested AMSOIL and know how good it is and many auto engineers even use it in their own vehicles.  We believe they will not use it in production for purely "political reasons" that all boil down to company profit. It is our opinion that there is a motive problem in the marketplace: oil companies need to sell large volumes of oil, and OEM engineers can tell you from personal experience that 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 many years. So petroleum oil appears to perfectly accomplish the objectives of both the petroleum oil companies and the equipment OEM's.

AMSOIL has been proven for 35 years to prevent your vehicle from having a short 150,000 to 300,000 mile life.  In fact, your Dodge Cummins can go over a million miles with Amsoil.  How do we know?  We could talk about diesels, but everyone knows gas engines aren't as durable...

I have an article about 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 if everybody used AMSOIL and got that much mileage on their vehicles?

Sure, the auto companies like to hear reports of stuff like this once every year or two --  but not on a large scale, because it would have major negative economic implications. 

Newer Amsoil synthetic oil and filter technology have recently enabled the "million mile van" using 25,000 mile synthetic oil and nanofiber filter changes, and 150,000 mile transmission and differential synthetic fluid changes.  Just think of how much money was saved by not replacing that commercial van every 200,000 miles, and never having transmission repairs!   And if a Chevy 5.7L gas engine can last 930,000 miles with almost no wear and stop because of defective valve keepers that were not hardened to spec and wore out prematurely... imagine how long your Cummins can last.

Few people in the business of selling petroleum oil and repairing vehicles have the character it takes to tell you how to extend your drain intervals using AMSOIL technology.  And although they've had some training, they actually know very little, if anything, about the technical and engineering aspects of lubrication, filtration and oil analysis science. Is AMSOIL just a scam?  Visit our special Amsoil skeptics Q&A to find out.

How to Reduce or Prevent Turbocharger Bearing Seizures on Cummins Turbo-Diesels

One of many specific ways that turbocharged Cummins Diesel engines can clearly benefit from the use of synthetic oil is the turbocharger itself. When a turbocharged engine is shut off immediately after use, bearing "heat soak" occurs due to the heat that naturally flows out of the hot exhaust manifold and into the turbo, adding to the high temperatures still present in the turbocharger: all this heat "soaks" into the bearings which are no longer being cooled by a flow of engine oil.  Over a period of time this can lead to deposits that can reduce or block the oil flow to the turbocharger bearings, which can lead to turbocharger bearing seizure.

The hotter the outside temperature and the heavier your load, the greater the risk to your turbocharger's life.

To combat these problems and give your turbo maximum life, our engineering staff recommend two things: 1) use of a turbo cool-down timer, and 2) one of AMSOIL's Synthetic Diesel Oils (listed below).  A cool-down timer gives your engine a chance to lower the EGT (Exhaust Gas Temperature) to a safer level before the engine shuts off.  A full PAO (Poly-Alpha-Olefin) Group IV synthetic does not break down and form deposits in the same temperature range as petroleum ("mineral") oils.  Of these two, a high-quality synthetic oil is the most important.

AMSOIL's Synthetic Diesel Oils are inherently more thermally stable than most diesel oils on the market, and have been shown to keep turbochargers considerably cleaner than other brands of oil. In fact, AMSOIL synthetics have a noted historical reputation for maintaining turbochargers in a clean like-new condition.  Meanwhile, 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 typical or low-quality diesel oils, it is critical that 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 when using petroleum diesel oils, but it can dramatically reduce it.

Take a look at the varnish deposits in this picture below. These are the results of a severe high temperature deposit test with some of the most trusted commercial brands. This test clearly shows that AMSOIL keeps engines cleaner longer than other major brands of diesel oils. Which oil would you rather have protecting your engine?

The bottom line: To prevent or eliminate 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 to show you how using superior AMSOIL products will increase the performance and add to the longevity of your Cummins Diesel, while saving you time and money. Cummins Turbo-Diesel trucks are excellent vehicles and exceptionally well engineered by Dodge.  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.

Skeptical? No problem!

Read our Q&A with hardcore "scamsoil skeptics"

Long life: We have an article describing 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 performance is unheard of in basic passenger vehicles with conventional petroleum oils, but is not uncommon when using AMSOIL synthetic lubricants.  Just think of how much money was saved by not replacing that van every 200,000 miles!

Improved Cummins fuel economy savings:  

While most customers will only get a 5 to 10% fuel economy improvement (my diesel truck gained 8%, my car mpg improved 10%), gains of 20% are not uncommon.  Phillip is a customer with a 1999 Oldsmobile Silhouette van who had changed his motor oil at 3,000 mile intervals.  In the spring of 2005 when he used Engine Flush and changed to AMSOIL engine oil with about 85,000 miles on the odometer, he got an instant 20% fuel economy increase which has been saving him about $12 per week.  That annual savings of more than $600 is six times more than the $100 annual cost of the AMSOIL products.

CAUTION !         BIO-DIESEL FUEL ?         CAUTION !

BIO-DIESEL FUEL CAUTION

Biodiesel fuels produce more rapid 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 will 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 is likely to produce engine damage due to oil failure.  [MORE]

Which engine oil should you use
in your Cummins Turbo-Diesel?

Your two choices for pre-2007 Cummins Diesels are the 15W-40 Premium Heavy Duty Diesel & Marine oil (product AME), or the Series 3000 5W-30 Heavy Duty Diesel Motor Oil (product HDD).  For 2007 and later diesels, those models are equipped with the Diesel Particulate Filters (DPF's), and your truck requires Synthetic 5W-40 Premium Diesel Motor Oil (product DEO) which exceeds the new CJ-4 specification.

Download Free Diesel Oil Guide & Comparison

(1.3 mb pdf)

Despite your owner's manual recommendation of a 15W-40 oil, your Cummins engine - like nearly all engines - is designed to use a 30-weight oil.  The 15W-40 recommendation is based on the assumption of petroleum oils which will often "shear back" to a 30-weight oil in diesels, and if you use a 30-weight oil that shears back to a 20 weight oil you will have wear problems (or worse).  Of course, AMSOIL's HDD formulation will maintain viscosity as long as you are using it as recommended in a healthy engine (no fuel getting in the oil, for example) - so your engine will enjoy year-round benefit from the 30-weight oil it was designed for. 

Both the AME and HDD oils are 25,000 mile oils that outperform every other available diesel oil on the market, and are LESS EXPENSIVE to use because of those extended drain intervals.  Both oils are also superb performers in gasoline engines.  The DEO oil exceeds the performance of any other CJ-4 oil on the market.  Any of the three oils will work well for you, but our best recommendation is for you to make an informed choice based on your specific needs.  Here are some suggestions to help you:

        For this Application...                                         Pick this oil:

  2007 & later models (CJ-4 spec is req'd)**                       5W-40 (DEO)

             Fuel Economy                                           Series 3000 5W-30 (HDD)

    Cold Temperature Performance                             Series 3000 5W-30 (HDD)

    All-fleet oil for home/farm/garden                     5W-30 (HDD), or any of the three

            Lowest oil usage                                     15W-40 (AME) or 5W-40 (DEO)

          OTR Freight Hauling                           5W-30 (HDD), 5W-40 (DEO), 15W-40 (AME)*

       All-fleet oil for class 3-8                              15W-40 (AME) - or 5W-30 (HDD)**

All-purpose oil for logging/heavy-construction           15W-40 (AME), 5W-40 (DEO)*

*While it is difficult to compare them, Engineers generally believe the thicker 40-weight oils (AME & DEO) may provide slightly more wear protection than 5W-30 (HDD) in extremely heavy applications, particularly off-road/gravel where drivetrains can be subject to heavy torsional shock-loading.  However, for highway/city mileage, HDD fuel economy savings probably exceed savings from reduced wear with AME - if there is any reduced wear at all with AME.  Experience has shown that changing to any of these three AMSOIL synthetic oils will produce fuel economy benefits.

**5W-40 (DEO) oil is also a fully backwards compatible, all-fleet oil.  So if using one oil for your entire fleet is one of your most important considerations, and your fleet includes 2007+ diesels (or earlier with DPF's), this is the oil to use.  However, be aware that the low TBN restrictions of the CJ-4 spec means that extended drain intervals will not be possible on your vehicles without oil sampling analysis.  (DEO has a TBN of 8.0, vs 12+ for AME & HDD.)  For this reason, our best recommendation is to use two fleet oils.  One for gas and 2006 or older diesels, and the other for 2007+ diesels.
 

Simply changing your 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. 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!

Dodge Cummins Owners Questions and Answers

Q:  Changing Fluids in my Dodge Ram Cummins truck? [Adapted from a GMC D/A question, because we felt that Dodge owners deserved the same information]

I have a 4x4 with a 6-speed standard gearbox.  I bought it new in 2001 and now have 98 000 miles on it.  Over the years I always made sure that the maintenance was done as per the owner manual but something bugs me.  Nowhere in the schedule maintenance does it talk about gearbox oil change.  They cover the engine oil, the engine coolant system and all kinds of minor items but they never talk about the standard transmission, the transfer case, the rear and front differentials, and what about the power steering and the hydraulic clutch?  How many years can we go without replacing the oil in all these components?  I understand that they use synthetic oil these days but are these synthetic oils good for the life of the truck?

AMSOIL has been in business since 1972 and was the first company in the world to develop an API (American Petroleum Institute) rated synthetic lubricant for automotive applications. They coined the phrase "extended drain intervals" 30 years ago with 25,000 mile drain intervals, and ever since then they have been defining the leading edge of lubrication technology, innovation and performance.  No other company in the world offers 25,000 and 35,000 mile oil changes, and AMSOIL guarantees their product performance. No-one else does that. AMSOIL is the Gold Standard in lubrication and filtration, and amazingly, their superior-performance products are cheaper to use.  The fact is, if you’re not using AMSOIL lubricants, you’re wasting money.

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...

OIL FILTERS:

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.

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:

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, and have OEM certified fitment for your vehicle.  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:

AMSOIL offers a growing line of the only OEM certified air induction filtration systems on the market.  Offering dramatic airflow improvements for gains in horsepower, fuel economy, and towing torque, they also keep wear particles out of your engine better than any marketed product.  Current air inductions systems include the 7.3 liter PowerStroke.  In addition, AMSOIL has released a full line of nanofiber universal air induction filters (EaAU) 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 than oiled gauze.  AMSOIL Ea Air Induction Filters are dry no-oil filters that offer far better efficiency, 50 times the capacity, excellent airflow and are easily cleanable.
