Dodge Cummins Recommendations

AMSOIL Motor Oil, interval and Filter Recommendation For Dodge Cummins Turbo Diesel Trucks

AMSOIL saves Dodge Cummins owners on diesel fuel and maintenance.

Dodge Diesel Owners Can Reduce Costs and Improve Performance

AMSOIL HD 15W40 and 5W30 increases MPG 3% to 8%
The #1 comment is regarding the improved mileage and smoother engine performance. AMSOIL is the only synthetic diesel oil designed for extended intervals which can resist the added shear caused by new diesel emissions systems which increase soot, heat, foaming and rust.. Find out why people have trusted AMSOIL Diesel oils since 1976.

Reach 20,000 + miles before changing oil.

Use the By-Pass filter system to reach 100,000 and beyond.

Required Capacities: Dodge Cummins 5.9 uses our Donaldson **ELF7349 Oil filter or the BMK-15 By-Pass Filtration Kit

UPDATE: 12-29-2005
New By-Pass Recommendation - From this point forward the new recommendation for 2004 and newer Dodge Ram trucks equipped with Cummins Diesel 5.9 L engines is a BMK-11 with special adaptor, instead of the BMK-15 By-Pass System. All new application guides and price lists will be modified for this recommendation.  Please make note of it in your current price lists and application guides as well.

** See information on the new Donaldson Endurance Nanotechnology oil filter - The ELF7349

1997 to 2003 - Engine uses 10 quarts plus filter (2.75 US Gallons).  The 04 & 05 use 12 quarts.

First, be sure you have surpassed at least the 5000 to 20,000 mile break in period. The Dodge Cummins 5.9 turbo diesel manual states: (1998.5 to 2002) Maintenance requires the regular replacement of oil and oil filters at 7,500 miles.

And the 2003 and up says: For 2004, the oil change interval has doubled to 15,000 miles for normal use, and 7,500 for severe use (towing). California, Maine and Massachusetts engines remain at 7,500 and 3,750 for normal and severe use, respectively.

Now, AMSOIL HDD Series 3000 5W30 and  AME 15W40 is rated for all turbodiesel engines, heavy-duty diesel engines, non-turbodiesel engines, and light duty diesel engines for drain intervals at least twice the recommended interval or 6-months whichever comes first.  Extend your changes further as outlined below using our simple Oil Analysis kits. With Analysis expect to double or triple the manufactures suggested interval. Because with analysis, you have hard evidence of the condition of the oil and engine, thus you will know exactly when to change oil and have a better understanding of AMSOIL quality and why we make the recommendation we do. No warranties can be effected. 

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

Keep it simple

We have many Dodge Cummins customers who have simply gone to a 15,000 mile interval of changing both filters on the bypass unit and no analysis. No, they are not draining the oil - Just changing the filters. (If you want to extend longer then we suggest the Oil Analysis kits) One dealer suggests changing the full flow and bypass filter at 10,000 miles for the first service, then 15,000 miles each time after that. You should never have to actually drain the engine oil using this procedure. 

The below is using AMSOIL w/o the bypass system:
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. Then once you have installed the appropriate AMSOIL synthetic oil and filter, change your filter and top off at your next normal interval. Example, If you are doing 7500 mile oil changes currently, change your AMSOIL SDF filter at that point (no longer than 10,000 miles), then top off the oil. You should now be able to reach 15,000 to 20,000 miles (with a filter change in the center of that interval) then drain and fill with your next filter. That is the basic coverage for AMSOIL's synthetic diesel motor oils as stated on the data sheets. AMSOIL Synthetic Diesel Oils are designed to last at least twice the manufacturers recommended interval.

I personally suggest once you reach the manufacturers recommended interval (3,750, 7500 or 15,000) to change the oil filter (Donaldson ELF7349) and top off. At this point you may want to get the engine back to operating temperature and pull a sample for your own piece of mind. Our kits are postage paid and simple to use. More about that below. Next when you reach your next incremental interval, change the filter again, top off, and sample again as needed. In most cases the sample will come back, "No Corrective Action Required. Oil Is Suitable for Continued Use. Resample at Next Normal Interval."

If you have not seen the data on AMSOIL's superior synthetic diesel product, before you leave please visit our Synthetic Diesel Oil section but first check out the By-Pass filter section below.  AMSOIL 15W40 and Series 3000 5W30 is best priced in our 4-gallon case or larger containers.

The most common comment I get from my diesel customers (most use the lower price 15W40) is, "I expected a little increase in mileage but nothing like this! I can't believe it!" 

With the 15W40 you simply cannot get a better value in motor oil. Since 1976 this has been improved constantly to exceed all future engine, EPA and API requirements. Try it out and you will never switch back. If you are in extreme low temperature areas, we also suggest the AMS-Oiler for easier winter starting.

Change your Mind - NOT Your Oil!

Switch to AMSOIL 15W40 or 5W30 HDD save time, fuel and cut your oil consumption significantly.

This means your use of AMSOIL HDD in the Dodge Cummins can generally be used up to 25,000 miles w/ analysis or 6 months if no analysis is used. Knowing that Cummins 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?  Why spend more money on a oil product that basically turns to acid prematurely and does not hold its viscosity? Today's EGR turbodiesel operate at higher temperatures and RPM thus the increase in oil sequence testing demands and new proposed specifications.

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 your results will return saying - continue use till next interval - change filter 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 Dodge Cummins recommended intervals (3,750, 7500 or 15,000)  and changing the filter at that time of (SDF-80) interval you will likely reach beyond 22,000 miles and save the cost of several changes, less wear on your engine and better gas mileage. With analysis you always win!

"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 for your Cummins Turbodiesel ask for two or three Donaldson Nanotechnology filters, one 4-gallon or 5-gallon case of (AME) 15W40, two test kits (G-1451) and a can of our (AEF-CN) engine flush 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, simply add the can to the old, existing oil, idle for 15 minutes and drain.

Once you have changed your oil, watch your mileage. Most customers are pleased with the added mileage. Try our Heavy Duty Diesel (HDD) 5W30 for even more efficiency in the Dodge.

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

By-Pass Filtration (BMK-15)

Use our By-Pass filtration kits and extend changes even further while virtually eliminating all engine wear. (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 a decrease in engine drag. Our gear and differential lubes will add to the economy. Dave Mann - Dealer in Detroit Michigan has Interstate Batteries of Detroit, Inc. using them and the entire state of North Carolina has done studies proving the relevancy and value of these units in their busses. Interstate Batteries couldn't believe Dave's recommendation 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, "My average truck life has increased by several years!" says the president of the Detroit division. He says he has also picked up a 5% fuel savings. (they 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. Generally costs between $150 to $240 each depending on which engine you have and if you use the single, dual remote or Dual Guard. With the By-Pass system you can also cut the frequency of analysis. Do one each time you change a Bypass filter (every 25,000 miles or once each year).

For your Dodge Cummins order the BMK-15 mounting system. This includes the SDF-26 full flow filter and the BE-100 By-Pass filter. You should also purchase the BK-13 test petcock valve ($8.25) and the BK-11 90* adapter kit ($25.00). For more information please visit the description on the AMSOIL filter kits.

In Turbodiesel applications our Donaldson Full-Flow Filters are recommended for 7000 to 10,000 miles or 6 months whichever comes first without analysis. 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. For the best price on all AMSOIL products sign up as a Preferred Customer for just $20 per year and order direct wholesale.

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!  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.

A short note from Al Amatuzio - Founder of AMSOIL (May 2005)

The other day I was reviewing the April Action News and the new G-100 product catalog included in it. The products featured in this issue were our two new motorcycle oils. Anyone reading about these outstanding new oils couldn’t help be impressed by how they totally blew the competition away in head-to-head performance tests. 

Once again, AMSOIL outperforms the competition and puts test results that prove it right there for everyone to see. It’s also interesting that the very bike manufacturer that said not to use synthetic motor oils in their engines now sells and recommends a synthetic motor oil with their label on it. 
They don’t make it, but they profit from it so now it’s OK to use. That’s very similar to how the other oil companies and automakers badmouthed synthetic motor oils until they began marketing their own synthetic oils. 
Are their oils as good as AMSOIL? Not when you look at the tests! AMSOIL has a long history of making lubricants that are the very best. And the way we have shown they are the best is by testing them against the competition and publishing the results in our sales literature or right on the product labels. 
I don’t know of any other oil company that does this like we do. But then, I don’t know of any other oil company that makes products as good as we do, so they don’t really have as much to toot their horn about as we do.
