I've been using Amsoil in my 04 Ram 5.9 L Cummins almost since it was new. 280,000 miles and no engine problems at all! Love it!

Solid premium product. I try to take care of my vehicles the same way I do my body. I look for the full protection of the lubrication this product provides in the rigorous operations I put my truck through, and the many miles I do. I'm happy with it.

Have used the diesel oil in my Ram from Day one. I believe it's the best on the market. I trust it.

Changed all the fluids in my 99 Superduty(220000 miles) over to Amsoil products. Truck starts easier in cold weather trans temps have dropped 10-15 degrees towing and I gained 2 MPG.

Was using Mobil Delvac 1. Would change oil at 15000 miles, changing the filter at 7500. Doing oil analysis at 15000 miles the oil was at 70%. Switching to Amsoil I change at 25000 changing the filter at 12500 the oil is just a little over 80%. Results speak for themselves.

I am using the amsoil for the last five years About 100,000 and 120,000 miles per years My semi truck and me we are happy and saving money it's amazing for the best

In my diesel trucks. Awesome oil. Lasts 25000km before I even think of changing it.

Run this oil in my 2012 Duramax. Can go a full year without oil change. Saves me money. Also use the Amsoil filter.

Love it. Good quality oil for a good price for this quality oil. Will Definitely buy again as its cheaper to do it my self than having the dealer do it and I get a way better oil for my truck.

ALSO IN MY SS2 CAMARO

Been using Amsoil diesel oil and Ea08 filters every 15k since the truck turned 30k miles. Have 276k now. Could do a longer interval with testing

I am relatively new to Amsoil but have and have both Duramax and Cummins - currently have a L5P Duramax with an Amsoil Duel Bypass oil filter set up which I did not have on my previous Duramax. Thus, apples to apples may not be in the following: 1. Blackstone reports come back much better than with the Rotella T-6 I was using in the prior '15 Duramax actually with about 7500 vs 5000 miles. I got some usage w/Rotella T6. 2. A bit of oil usage with the Rotella t-6 but absolutely none with the Amsoil. Repeat not apples to apples exactly as different engines and the L%P has a duel bypass set up on it.

I use the 5w40 and 15w40 in my 2003 Dodge Ram 2500 5.9 cummins ... when I got the truck it had 378,000 also had little blow-by.. it ran mobile 1 most of its life .. switched to AMSOIL signature series (max-duty) and the blow-by was gone and it also slowed down completely with drinking some oil .. 7-10,000 and I might need to add 1/2 qt this stuff is AWESOME .. now I have 429,000 and this cummins runs like its NEW with 10,000 miles on it .. everyone that I know with a cummins , I get them hocked on it also .. everything I own has AMSOIL

Used in all my vehicles for years

Maintenance

I use this oil in my '02 2500 Ram Diesel to protect that engine for the long haul. The 5.9L Cummins is the last of the "loud ones" for Dodge. I want to try for 750,000 to 1 million miles before it needs any real work put into it. That sound is one of the reasons that I bought it in the first placeI love how it runs and I get great longevity out of the oil. If you run a diesel you would be crazy to not try some in yours. Worth every penny!

I have always run synthetic oil in everything, but since I bought my Duramax, I thought I'd try you product and filter. So far so good, I'll let you know in about 150000 miles.

This is the only product that I can find that is recommended for my Eco Diesel and it performs as advertised.

Great stuff wouldn't use anything else.

First time have used Amsoil diesel oil. So far so good. However I didn't notice much change in fuel economy after using Amsoil 5W40 SS diesel oil for my first oil change in this truck, in town driving. High way driving did show some improvement, all the way up to 30.2 mpg, previously had gotten 29 mpg. I think part of this is my motor is still breaking in as diesels take awhile to do so. Overall I am pleased & have used Amsoil in both of our vehicles going on 18 years.
