We have a 2016 Ram 1500 Ecodiesel and prior to using this product I was eating up half a tank of DEF every month. I ran back to back bottles and started using the DEF at our local Fry’s store. The DEF consumption went down dramatically. Folks, this stuff really works. We are having to fill the DEF every two months now. Fantastic product and works extremely well.

I bought a used 2021 F250 with 75k miles. At first it was drinking DEF. I used 3/4 of a tank on a 900 mile road trip. I used this product on the first tank on my 5900 mile move to Alaska from Virginia. The first 3/4 tank of DEF, with the product in it, got me to Indianapolis, about 800 miles. The second tank I started using the Rislone DEF Treatment in every box I put in the truck, it got me to Mitchell, SD which was about 1000 miles and I used half a tank. About 1200 miles later I put 1 box of DEF in before I crossed into Canada, and stocked up on 3 boxes knowing I had about 3k more to go. Keep in mind, I'm hauling a 20ft enclosed trailer full of all my earthly possessions, and I have quite a few tools and heavy things. Something happened after that first 3k miles. I made it the next 3k miles and only used 1/2 tank. Now when I fill up it says 7500 miles to empty. I don't know if that's true, but it's been a long time since I've had to buy DEF.

BMW of Roseville diagnosed a faulty SCR sensor. $6,700 for a new DEF tank was quoted. Rislone fixed it for $20.

I used this in DEF tank since I had been geting P20EE codes regularly. I could see crystalization around pour tube, cap, etc. I put this in, then I got the dreaded Poor DEF Quality message and P20EE code again. Then it went away. A few miles later, back again. Then after a few days. maybe 75-80 miles, no more codes. Took a long trip of 650 miles, plus local driving, code and DEF message have never appeared again. Seems to do the trick. I also add in the Rislone maintenance DEF fluid product. Seems to all be working as intended.
