Rislone® 4744 DPF CLEAN™ Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 oz, 1-Pack

2019 Silverado Duramax (Only 49k miles but out of time warranty) in limp mode reduced power, Check Engine Light On and Trouble Code P2002. Repair shop could not force re-gen or could clear the code, they quoted $3,600 to replace the DPF so I parked the truck until I could afford the repairs. In the meantime I saw a U-tube video talking about this Rislone DPF Cleaner and the success that people were having. I figured why not give it a try so I bought two bottles. I followed the simple instructions and completed the process twice for good measure and WALLAH!! Engine Check Light went off, Power was restored and I removed the code with a OBD2 scanner. Have over 200 miles now and no issues....I'm SOLD on this stuff, it sure worked for me .

Works! So does the their def additive. Got me off the side of the road in my 2019 Ram 3500 Dually 6.7 diesel. Putting these in made my truck run better and started a regen. I’m sure it’s a bandaid but it works!

good stuff, but not much useful unless your dpf is really clocked badly.

CEL came on in my 2013 BMW X5 Diesel. Code was for Diesel Particulate Filter (DPF) being compromised. Independent mechanic wouldn't touch the diesel emissions system; BMW wanted over $4,000.00 to assess and clean (the DPF is pretty buried under the car and the $4K was almost all labor). With 1/2 tank of fuel in the vehicle, I poured 2 bottles into the tank and drove the car at 70 - 75 mph for about an hour. Code cleared, and CEL went out. the $50 I paid for the 2 bottles saved me at LEAST $3950.00. I'd say it is a great value and heartily endorse the product. I plan to introduce a bottle to probably every 4th or 5th tank of fuel to maintain DPF cleanliness. I give this product a full 5 stars - it is NOT snake oil. Beat Navy!!!

2018 Ram 2500 6.7 Cummins. Put it in the DEF Tank while it was at 1/4. Drove until the def tank was almost empty. It definitely worked. I did use at a higher concentration that the directions say but I had to try something fast. It cleared up the filter and nozzle.

This is a fantastic product! I have a diesel BMW wagon, and after pulling codes realized it was the DPF. Put this in a half tank of diesel, ran it for 40 miles, drove it next day and light and codes went away!

No more p2002 code thanks to this product

I drive a diesel truck and strive to take care of it so it takes care of me. This is a treatment I use every 5,000 miles by adding a bottle to my fuel tank when it’s half full. I concentrate it at that level to get the most cleaning for my trucks DPF, turbo, EGR, and exhaust system.
