I have used the DME on 6 different GM 6.6L diesels, and have never had a problem. I towed boats with earlier trucks, and now farm use with the current truck and the DME is an outstanding oil for this engine.

I have used this oil in my 2002 diesel truck for many years and won't change.

I always used valvoline premium blue then I tried this stuff 1 time and I’m hooked I have literally swapped all fluids in all my vehicles and toys generators etc to amsoil even my family members have switched to this oil in their vehicles I even used the quick shot fuel additive in my 44 year old truck and it woke up that old Quadra jet carb! Don’t hesitate to buy this! I am in the process of putting their dirtbike oil in my dirt bike at this very second!!

great oil and fast shipping got to my door steps in 2 days keep up the great work Amsoil

178,000 miles and still going strong in my 2012 F350 4x4. Amsoil is all I use on my Truck.

Use this in my powerstroke for the past 17 years

Great oil always changed the engine oil at 15k miles with the 6X and now I use 4X and change it at 10k miles. Oil samples come back great. '10 Ram with a Cummins 6.7L- Been using AmsOil on it for 120k miles still going strong!

Been using this oil for awhile and seems to run a little quieter. Extremely happy with this product.

Got the oil in a good time but didn't get the filter at the same time was kinda disappointed because I had scheduled to get the oil change done. So I had to go buy a filter from napa.

Only oil I’ll run in my 6.0 powerstroke

I've been using this oil in my 04 6.0 diesel for a couple years now and I'm very pleased with how it runs and feel it's the best oil for longevity.

I have an older Dodge Cummins diesel and this oil checked all the Marks at a great price.

Top quality oil and filter, super fast shipping. For sure a repeat customer!

I like your services and I like your products I’m very happy with them

Best oil ever for my 2018 Sierra Duramax!!!.

See previous review!

I used Amsoil years ago in my 02 durmax and saw instant fuel millage increase and then I switched to shell rotella t6 synthetic, thinking I would get the same performance. I could never get over 17mpg with rotella t6 so I switched back to Amsoil and again I saw an instant increase of 2mpg and now I get 19 unloaded. I also saw a significant increase pulling my 8,000 lbs camper. I recently pulled through Cherokee Nc and through the Smokey Mt. Pkwy into Gatlinburg Tn. I averaged 13.5 mpg ! I will never use anything else in my durmax again.

The truck has been driven about 800 miles since the oil change. The oil is still at the full mark on the dipstick. The history of the last oil change (and the first of my ownership with this truck) is that the engine used a quart of oil in about 2,000 miles. In my opinion, still a little soon to really rate the oil's performance.

This oil eases cold starts in cooler weather and lengthens the interval between oil changes. I used to change at 8000 km with conventional oils and it was black, this oil I change at 10,000 and it is as clean as the day it was changed.

Great oil, Great prices and very fast shipping!
