This means your use of AMSOIL HDD in your Powerstroke can generally be used up to 25,000 miles w/ analysis or 6 months if no analysis is used. Knowing that Ford designs these intervals to be conservative (using conventional SAE 40 motor oils), the use of an oil analysis will generally prove that the AMSOIL HDD (or AME) is still within the proper specs regarding to alkalinity, wear metals, soot, NOx% (nitration and oxidation), water, fuel, etc.. The ANALYSIS company makes the recommendation but you see the results yourself. Why in the world would you change the oil if it's still good?  And why would you use another oil when AMSOIL users experience instant fuel economy increases of 5% to 15%??  (6% to 15% when AMSOIL is used through out the power train and intake filters)

It is highly likely when using analysis (cost less than $20.00) that the results will return saying - "continue use till next interval - change filter if not done at last sample and top off.."  It's still good! you save money, have a new filter and replaced about 2-quarts raising the level of acid and soot control even when new EGR systems are used. 

By running analysis at the Ford recommended intervals (7000 miles)  and changing the filter at that time of  the (SDF-99 filter for Powerstroke) interval you will likely reach 20,000 miles on that oil and save the cost of several changes, less wear on your engine and better gas mileage. With analysis you always win! Just benchmark it the first time around.

"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 two SDF-99 filters, one 4-gallon case of (AME) 15W40, one or two test kits (G-1451) and 1 can of our (AEF-CN) engine flush for high mileage changeovers when converting to synthetic 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. This will also bring the oil level down enough to add the cans (follow instructions on can - one can per 5 quarts sump) and catch more of the deposits assuming your current filter has expired.

By-Pass Remote Filtration Units - Eliminate virtually all engine wear

By-Pass Filtration (BMK-16)

Use our By-Pass filtration kits and extend changes even further (Filters down to 1/10 micron particle size 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 100,000 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.) 

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

For your Ford Powerstroke or International Diesels order the BMK-16 mounting system. Includes the SDF-26 full flow filter and the BE-100 By-Pass unit. For more information please visit the description on the AMSOIL filter kits.

In Turbodiesel applications our AMSOIL SDF Full-Flow Filters are recommended for 7000 miles or 6 months whichever comes first. Change other manufactures' filters at the engine manufacturer's recommended filter change intervals.

In Heavy Duty Diesel trucks it in not unusual for the engine manufacturer to recommend 25,000 and 50,000 without By-Pass filtration. Mack has designed an engine for 40,000 miles per change recently. AMSOIL has been tested on the road using analysis and By-Pass filtration for up to 409,000 miles.

Testimonial: Several of our customers using the diesel products for the first time always send feedback regarding their amazement on how well the oil actually performed. They can't believe how smooth the engine now runs and sometimes the mileage quoted sounds very exaggerated!  One of my customers actually made it into the 2003 AMSOIL calendar!  Don't forget to examine the AMSOIL gear and transmission products to maximize your efficiency and totally extend all your fluid requirements.

• ANALYSIS KITS - These kits retail for about $20 retail with two way postage included. To sample your oil you can either purchase the $25 pump with hose (Vampire™ Hand Pump - same as military uses) for easy extraction from the dipstick tube. You may drain a portion from the drain plug (difficult to get a representative sample) or if you have the By-Pass kit use the drain valve attached to the manifold for the quick and easy extraction. 

• Contact us for these kits. Non postage kits sell for around $15 if you need to do several vehicles together. Co-op discounts available for fleets. 

Keep your fuel system clean. Posted on the "Diesel Page" was a recent article by Kennedy Diesel aftermarket parts (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.  We suggest using the AMSOIL Diesel Fuel Additive to keep injectors clean and lubricated properly. 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. 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.

TS-103 and TS-118 AMSOIL Flowzair Air filter for Ford 7.3 Powerstrokes 

 Air restriction will kill performance in a TURBO charged diesel. Take advantage of AMSOIL's newly re-engineered 2-stage foam air filters. Same pricing, better materials. A properly designed dual-stage oiled-foam element traps dirt better than any other filter media. AMSOIL has recently upgraded their materials for more dispersant area in the foam.   The 2^nd stage material is a new Polyethylene closed cell based mater treated with a new filter oil. This new material contains 125,000 ppi3 (pores per cubic inch). And the 1^st stage a new 8000 ppi3 pores per cubic inch. Delivers a phenomenal 2000 SQft of filtration surface area per cubic foot of filter media. More contamination trapping surface area than any filter known. Now an 18% better air flow and 99.5% cumulative efficiency rating.

Also re-designed  is the gasket sealing edge utilizing a new base material. A blue Ethylene Vinyl Acetate (EVA), which not only looks better, but also creates an un-compromised seal, better fit and designed to be used over several times. Vibration proof positive sealing with as little as 10% compression and more. 

The metal support frame has been improved to an 18-gauge and the hole size changed to 3.96 mm circular–turbo-perforations to assure air flow is maximized! Typically weaker materials would flex under turbocharger vacuum.

We can also offer you a great price on Hastings fuel filters which should not be ignored for regular maintenance or you may loose all performance. The fuel filters are the most overlooked part in most diesel engines.

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 offers better protective film at higher temperatures than conventional SAE 40 oils while retaining fluidity at subzero temperatures.
