#4 – Diesel Fuel Additives all relating to the varous Ford Powerstroke models.

Oil Recommendations:
AMSOIL DMO 5W40 and DME 15W40 (CJ4 for 2007 and newer)

For 2006 and earlier use the higher Zinc and detergency CI4+ rated oils which are best for the long life of your engine and contribute to the cleanest possible crankcase.
Here are AMSOIL’s “High Zinc” products that are available: AME 15W40 CI4, ACD 10W30 and HDD 5W30 is often noted for increases of MPG 3% to 8%

The Ford 6.0 LOVES the HDD 5W30 – AMSOIL INC. directly quotes this oil works as if the engine was manufactured with the HDD 5W30 in mind. It will assist in high temperature climates too because it transfers heat better while the 100% synthetic base stock stands up to the abuse.

Most our 7.3 customers use the old AME 15W40 for 15,000 miles/1-year but many who like to stick with OEM oil changed are using the new low cost OED 15W40 and OEC 10W30 in winter.

For CJ4 Requirement – See this new report on AMSOIL’s reaction to the DPF fuel dilution problem & why Amsoil is the only choice for these newer engines. (use Amsoil DEO 5W40 or DME 15W40 on new models 2007 and up requiring CJ4 oil specification)
The #1 comment is regarding the improved mileage and smoother engine performance. AMSOIL is the only diesel oil designed for extended intervals under load which can resist the added sheer caused by new diesel emissions systems which increase soot, heat and average engine RPM. Find out why people have trusted AMSOIL Diesel oils since 1976.

We feel the best contribution AMSOIL has to your diesel next to our engine oils is our improved fuel additives for ULSD Fuel. You need to return the lubricants and additives removed by ULSD. The new AMSOIL ADF (See link) improves mileage enough to pay for the product as verified and tested over 12.5 million miles.

Please review these additives and our Q&A section on the Diesel Fuel Additives page.

Reach 25,000 miles or more before changing engine oil. You don’t have to go that long, but AMSOIL knows our diesel engine oils will neutralize soot and acids, retain its viscosity, resist sheer and reduce oil temperatures in turbo and non-turbocharged diesel engines for that duration. These products save you time, eliminate deposits, reduce oil consumption, reduce overall repairs needed, and most importantly reduce dependence on foreign oil.

A customer in Florida using the HDD 5W30, Power Core air filter (P603577), and SVO 70W140 in the differential commented instantly on a increase of 3MPG in his 6.0.

AMSOIL ATF Transmission Fluid lasts three times longer and reduces temperatures under load up to 50 degrees saving transmissions and fuel.

Use the BMK-21By-Pass filter system to reach 100,000 and beyond oil life while virtually eliminating wear and soot.

OIL FILTER: Ford Powerstroke 7.3 (94-03) uses the AMSOIL EaO-99 Oil Filter and the drop in EAA-728 AMSOIL absolute Efficiency Air filter. (air filter varies with year – call or check here)
The Full flow EaO-99 is a 1-year, 25,000 mile filter.

The 6.0 Uses it’s own special line of filters: The SDF-88 Donaldson/Motorcraft oil filter and the factory P603577 Donaldson Power Core air filter which you can buy from us by phone for less than the dealership or auto parts store. 800-579-0580.

OIL: Use the AME 15W40, ACD 10W30 HDD 5W30 or DME/DMO 5 & 15W40 (for CJ4 requirement) Synthetic Diesel engine oil. The life of these can be found on the pages resulting from the links.

PLEASE SEE Oct – 2009 – Amsoil Tech Service Bulletin – OEM Interval Recommendation
Subject: Fuel dilution issues in 2007 – 2010 (covers 2013 too) light-duty turbo-diesel pickups requiring CJ4 Rated Diesel Oils.

Don’t forget the AMSOIL Do It Yourself FLUSH. You need to get all of the old oil out and neutralize the acids to take advantage of the full benefits of AMSOIL diesel oils.One 16oz bottle is all you need. Our flush is not a solvent and residue will not harm the new oil as it’s now detergent based.

Please refer to our interval chart for more info.

Look up your vehicle’s filters, capacities, plugs, wires, wipers and Transmission/Drivetrain Fluids.

New – AMSOIL Low Viscosity – Replaces MERCON LV, SP – (Use AMSOIL ATL)
For all other automatic transmissions use the AMSOIL ATF. (Also meets SP available for the 6.0)
Decreases temperatures up to 50 degrees, improves power transfer, and lasts three times longer, the ATF is known as a problem solver for individuals and critical fleets.

For manual transmissions, transfer cases and differentials we have several choices for your Powerstroke.
Please use our application tables to find the right product for your truck or review the gear and transmission oils in the Drivetrain lubes section. To simplify things remember the Severe Gear for your differentials. This product already contains the limited slip track lock additive you need.

7.3L PowerStroke Air Induction System
(PCIS73) call 800-579-0580 for current price.

AMSOIL now carries a retrofit air induction system kit for Ford truck owners who operate their vehicles in dirty or dusty conditions. Biggest benefits include:

* Improved fuel economy
* Increased horsepower
* Greater filtering efficiency
* Greater filter capacity

Designed for Ford 250-550 pickup trucks built after January 1998 thru to the 2003 model year.

The new air induction system brings better performance to Ford owners. Diesel engines need clean, unrestricted air for optimal performance. The new Donaldson 7.3L PowerStroke Diesel air induction system with PowerCore technology provides better air filtration through better engineering.

Greater Filtering Efficiency
The Donaldson air induction system is three times more efficient than the industry-leading cellulose media. The layered structure from PowerCore technology is totally non-metallic and allows for 99.95 percent efficiency. The highly efficient Donaldson PowerCore air filter is the only aftermarket induction system that is approved by Ford Motor Company and sold by FORD. We will save you $.

AMSOIL Is The Solution
AMSOIL provides high-quality lubricants, filters and fuel additives for diesel applications that directly address the challenges of maintaining a diesel engine.
AMSOIL diesel oils deliver extraordinary lubrication in diesel commercial, fleet and personal vehicles. They are formulated with high-quality synthetic base stocks and premium additives to exceed the higher performance demands of diesel engines. AMSOIL diesel oils
withstand the stress of higher heat, higher acid levels and excessive soot-loading found in EGR-equipped engines.

AMSOIL Ea Air, Oil and By-Pass Filters provide top of-the-line filtration performance for diesel engines. Ea Air Filters are the most efficient filters on the market, preventing contaminants from entering sensitive diesel engines through the air intake. Ea Oil Filters offer maximum
efficiency over extended drain intervals. Ea By-Pass Oil Filters provide the best possible filtration protection against wear and oil degradation, while removing 39 percent of soot particles less than one micron.

AMSOIL also offers Injen/AMSOIL cold air intakes for many diesel applications, providing improved horsepower, torque and efficiency.
AMSOIL diesel fuel additives are formulated to combat the varied quality, cold-temperature performance and other issues diesel fuel can present. They provide improved lubricity, maximum pumpability and increased efficiency in diesel engines.


AMSOIL AME 15W40 is rated for the Ford Powerstroke 7.3 and 6.0 Turbodiesel for drain intervals 25,000 miles or one year. The same interval for our new AMSOIL EaO-99 oil filter (7.3) or EaO-88 (6.0). Simply run for up to 25,000/1-year for normal use or 15,000/1-year for severe service. See the Selection guide and Interval Chart. Both can be ordered through us.

We strongly recommend you review this article from Al Amatuzio (CEO of AMSOIL) regarding the AMSOIL Donaldson partnership and the quality of this company.

Increase economy even more using the AMSOIL Severe Gear 75W90, 110 or 75W140 which has a interval of 100,000 miles.

I suggest taking a oil sample before you convert to AMSOIL just to see the current condition of the oil and wear patterns especially if you bought your truck used. It will also help you gain an appreciation for the durability of AMSOIL Diesel engine oils. Call us for the kits or continue reading.

Start your Preferred Customer membership now to be notified of all the AMSOIL updates and improvements as well as “At Cost” buying.

I recommend the 15W40 AME in engines with higher mileage and the HDD 5W30 in new engines broken in. The ACD 10W30 is an excellent alternative for slightly better mileage. The HDD is great for efficiency but it features base stocks which allow the oil to not fluctuate in viscosity and anti-wear at all. Oil analysis tests will astonish you. Most of our 5W30 users quote an increase of 2 MPG.

The AME 15W40 is AMSOIL’s best selling product. Since 1976 this has been improved constantly to exceed all future engine, EPA and API requirements but the new DEO 5W40 continues on with the 2007 CJ4 rating while AMSOIL will keep the AME at the CI4+ while all of our competitors remove the better anti-wear oils from the shelf to consolidate space. Oils which meet the new CJ4 are backward compatible but do not have the life and antiwear additives you need in your 2006 and prior not to mention the detergent capacity. If you are in extreme low temperature areas, we also suggest the AMS-Oiler for more protection at winter starting.

Change your Mind – NOT Your Oil!

Switch to AMSOIL 15W40 or 5W30 HDD save time, fuel and cut your oil consumption significantly (use ACD 10W30 for year round protection in colder climates).

“I’m so tired of $60+ oil changes every 3 weeks and having to wait and watch over some one else change my oil! What is bulk oil anyway?” AMSOIL 15W40 is the solution to this problem!

For your first order (example 1994 and newer 7.3 TD) order one or two EaO-99 filters, one 4-gallon or 5-gallon case of (AME) 15W40 or ACD 10W30, one or two test kits optionally (KIT-02) and a can of our (FLSH-CN) engine flush for change over’s when converting to AMSOIL for the first time. For other engines there are several different filters so just provide the year and engine on your order request or catalog request.

If using the engine flush, I first start by purchasing a local oil filter just for the engine flush procedure. This will also bring the oil level down enough to add the can (follow instructions on can) and catch more of the deposits assuming your current filter has expired. Most AMSOIL diesel customers take advantage of our Preferred Customer program and buy direct to get the best price and ordering simplicity.

Call me at 1-800-579-0580 with questions and to order at a reasonable price or read about the Preferred Customer to buy at outright wholesale. There is a simple form for the trial 6-month membership. I can set you up as the preferred on the phone too. AMSOIL will mail you a packet with prices 15% to 35%.

We now have the new Absolute Efficiency filters available for the bypass line as well. Please see more on our dedicated Bypass Filter Page.

Use our By-Pass filtration kits and extend changes even further (Now 100% efficient at 2 microns and will hold up to a quart of water).. If you don’t use AMSOIL use the By-pass kit at least. It filters 5 quarts in 5 minutes at 45 miles per hour. When using AMSOIL HDD Diesel your engine will run smother, quieter and many even notice an increase in power. Our gear and differential lubes will add to the economy. These are mostly used by large fleets but we have hundreds of individual customers using them.

Recently the entire state of North Carolina performed extensive studies proving the relevancy and value of these units in their busses. Most don’t believe it at first, but now because of the use of the By-Pass filters and analysis they now clock over 200,000 miles on the oil and the life of their trucks are extended by several years. (Most use the low cost Heavy Duty Diesel and Marine 15W-40, AMSOIL grease, 75W-90 gear lube and the Universal ATF in the automatics.)

Keep it simple on the Bypass

We have many Ford Powerstroke customers using our bypass system who have simply gone to a 15,000 mile interval of changing both filters on the bypass unit and no analysis. The intervals have just been increased thanks to the new Nanofiber oil filters. Change the full flow at 25,000 miles and the bypass at 50,000 or every other time you change a full flow filter. No, they are not draining the oil – Just changing the filters. (We recommend you monitor the oil with the Oil Analysis kits. This in many instances will allow intervals to stretch even longer.)

Our best recommendation for standard service is to sample the oil at least once yearly when using the BMK-26Ea Bypass Kit or BMK-21 for 6.0 owners. Just change the full flow at the first 15,000 and bypass filter at 30,000 miles ( first service), top off the diesel oil, then 25,000 miles each time after that for full flow, then 50K or every other full flow (EAO) filter change for the bypass EaO-100 spin-on filter. You should never have to actually drain the engine oil using this procedure until about 250,000 miles as long as you perform oil analysis after servicing to see ahead. Proven and backed with 35 years of field service.

Oil analysis is the only way to know the condition of a lubricant beyond AMSOIL recommended intervals and typically saves fleets tens of thousands of dollars. It becomes clear how well AMSOIL AME 15W40 contains soot passing it more efficiently to the filters. This results in oil lasting three times longer than expected in heavy duty equipment such as refuse haulers.

How well do you think it will stand up in your work truck?

If you want to avoid problems with soot and deposits, the By-Pass and the ADC Diesel Fuel Concentrate is your solution. Call us for price or start the wholesale account today.

Keep your fuel system clean. Posted on the “Diesel Page” was a recent article by an engine rater (who recommends and sells AMSOIL Products), suggests a upgrade kit to the current fuel filtration system due to the less than stellar quality and cleanliness of the available diesel fuel here in the US. Improper combustion is the primary cause of soot in your engine. When clean fuel burns completely, the only by-products are water and carbon dioxide. Unfortunately today’s diesel engines are nowhere near 100% efficient and soot makes it’s way past the rings in the form of acids and NOX.
You can significantly reduce this when using the AMSOIL Diesel Fuel Additive. Primarily, this keeps injector pumps clean and lubricated properly while restoring proper spray patters lowering soot byproducts. This unique product also drops the gel points by 20° to 30° F allowing you to avoid more expensive winter fuels and additives. AMSOIL Diesel Fuel Additive is available at a great price.

“AMSOIL offers diesel fuel additives that provide real
results,” said Markham. “In northern climates, if you get
some fuel with a high cloud point you could find yourself
stranded somewhere. Offer prospects with diesel
vehicles a bottle of Diesel Concentrate Plus Cold Flow
Improver as a way to make sure they are protected.”

Fuel pressures as high as 23,000-psi demand much from the high-pressure pump and solenoid-controlled fuel injectors, so this is definitely an area to not overlook.
You can order a case of the
(ADF) Diesel Fuel Additive Concentrate with twelve 16 ounce cans for next to nothing if you call us. Treats 80 gallons each can.

EaA-103, EaA-118, or L Absolute Efficiency Air Filter for Ford 7.3 Powerstrokes (different per year)

 Air restriction will kill performance in a TURBO charged diesel. Take advantage of AMSOIL’s new 98.6% efficient @ 2-micron synthetic filters.

The new nanofiber technology used in AMSOIL Ea filters surpasses all other technology in efficiency, capacity and service life. With AMSOIL Ea Air Filters, dust and submicron particles remain on the surface and are trapped in the nanofibers, preventing particles from lodging in the filter media depth. This produces higher efficiency and higher capacity which extends engine and filter life and reduces engine wear.

AMSOIL Ea Air Filters hold up to five times more contaminants than cellulose air filters. Since the nanofibers in the media are so small there are more pores per square inch, allowing for higher dirt-holding capacity and lower pressure drop when compared to cellulose filter media alone. Thinner media fibers produce more uniform pore size distribution, improving the filter’s overall quality and ability to capture and retain particles. Testing shows that Ea Air Filters hold 15 times more contaminants than a wet gauze type filter. The capacity is so great, in fact, that the new AMSOIL Ea Air Filters remain effective for a full 25,000 miles or one year before cleaning. This coincides with the AMSOIL 25,000-mile/one-year motor oil drain interval, adding even more convenience for motorists by consolidating routine maintenance.

Q.  I have a 2001 Ford F-350 Pickup with a Powerstroke Diesel with 7000 miles. I’m getting ready to change over to synthetic oil. What AMSOIL motor oil would you recommend to use?

A. AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil is our premium top of the line product. While there are best uses for both our Series 3000 and our AMSOIL 15W40 Diesel and Marine Oil, Series 3000 is our recommendation for the Ford Powerstroke engine. It surpasses the API Energy Conserving Rating requirements designed to provide significant fuel savings. It has highly effective anti foam agents to prevent oil foaming. Series 3000 5W30 offers better protective film at higher temperatures than conventional SAE 40 oils while retaining fluidity at subzero temperatures.

FFK-60 Fuel Filter for Ford 6.0L DieselPowerStroke™ Applications The AMSOIL FFK-60 Fuel Filter incorporates both a primary and secondary filter for maximum fuel cleanliness. The primary 10 micron filter, located in the horizontal Fuel Conditioning Module (HFCM), performs initial fuel cleansing before sending the clean pressurized fuel to the secondary four micron filter, mounted to the oil filter housing. The secondary fuel filter includes a fuel pressure regulator and an orifice on top of the housing that bleeds air out of the housing and back to the fuel tank. Following its trip through the secondary filter, fuel is returned to the HFCM, where it is either directed to the tank returned to the primary filter.

AMSOIL EaO-88 Oil Filter for Ford 6.0L DieselPowerStroke™ Applications

The AMSOIL EaO-88 is the worlds first 100% synthetic cartridge type oils filter. Please see more on this product on our Absolute Efficiency information center.

Combine this with the extended intervals. Truck lasts longer with more money in your pocket. We stress to use ANSLYSIS to get the most from your dollar.
