Review: Great Product, Great Price. What more could you ask for, - I decided to go out on a limb and purchase this oil for my 2022 RAM 1500 EcoDiesel. I was paying $150 for 9 quarts of Mopar OEM 5W-40 oil and just was so tired of spending that money every 2 months. Plus the powertrain warranty was up at 100k and I said screw it. No i'm sure you've all heard the horror stories of the Ecodiesels. Before anything else, let me clarify. I purchased the truck brand new and has been completely trouble free. I average about 28mpg, with a 33 gallon tank, or 830ish miles of crusing range doing 75MPH. CP4 pump has not failed yet but I think by driving over 800 miles a week, it keeps it well oiled. Now as for the oil, It was really hard to believe that hard cold starts would disappear. That I can confirm. I'm down in Texas and its been cold, in the 40s and 30s, and it starts right up without any issue. Compared to the OEM oil, it would take a couple turns to crank over. Another thing I noticed is the oil temps run higher. Range with the OEM oil was around 206 vs now around 219. I have not noticed a real significant increase in MPG, still getting around the same 27 to 28 mpg. Truck does run smoother. Idle is a lot more quiet and not as "clunky." So far I've driven about 1300 miles with this oil and it has not even turned a spec black. Oil level has remained the same. Overall, I have been extremely impressed so far. I'm sure its not gonna kill the motor not using the correct "MS-12991" oil spec recommended but this has blown the OEM oil out the park. Oil is oil (in my opinion) but to each is own, just thought I would share my experience so far. Happy driving!

### ⭐⭐⭐⭐⭐ Impressed.
*by D***D on November 10, 2025*

My 2000 7.3 EX has never sounded this smooth, and not making laggy hiccups when switching to/from high idle tune. I didnt take it for a drive yet, but ran thru gears to listen to the pull after up-to-temp and Im already impressed. There is an obvious difference and I've run all the top brands.
