Rislone Diesel DEF Treatment, 8 oz (Pack of 6)

I think it's working not sure but truck runs a little better

Good product. Used on my 2015 F350, but I cannot really tell if this has helped or bot. Time will tell.

Used this product in late Aug early September, truck has 83k miles and has had new def tank at 40k. Almost instantly started having issues. Sensor after sensor, then def injector, tank cleaning and def fluid replaced seems to have cured the issue. I use my LML Duramax lightly and thought this would be a helpful solution…turns out I either had too much contamination already and this loosened it all up/sent it through and clogged everything or the product itself caused the issues Thousands later I’m 100 miles without fail safe mode threats from the dash after 3 months in of repairs

I don’t know if it helps or not. Truck is still running good

My def gauge was stuck. This was recommended to treat def and get rid of crystallization. I have added 3 bottles so far and no movement on gauge so far
