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

Values for money. Worked!!! Saved me a huge repair bill on my VW Passat.

This is a good product to use to keep DPF (diesel particulate filter) clean and to clean a dirty DPF to eliminate the check engine light code. One treatment has kept the CEL from reoccurring for the last 2000 miles since I used it. I plan to treat every 5000 miles as a precaution to clean the DPF and fuel injectors.

I started using this app uear ago when I had a DPF sensor issue. I replaced the sensor and have been using this every 5k since. This is what I have noticed. Quicker regeneration it takes have the time to complete a regen. Regeneration is less frequent and DPF indicator takes much longer to accumulate.. I know there's no real science behind my claims but it's hard to ignore . I used to have random exhaust codes too and those have stopped completely I get great MPGs and the 6.7 is always super smooth and quiet. This is just my observation in my situation but if your having regeneration and egr issues which we all know is common with these this rislone product has seemed to serve me well.

Took a while longer to work than the instructions but cleared message. Debating whether or not to buy one to have on hand.

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 .

This product cleared the CEL on my 2014 VW Jetta Sportwagen TDI. When the mileage reached around 140K, the CEL came on intermittently for a few months, then it stayed on solid. I guessed the problem had to do with the emissions system, so I bought this product. I figured it was worth trying for $100 or so because I knew dealer service would be expensive. It took two bottles to clear the CEL. I spaced them 500 miles apart. After extinguishing, the CEL has not returned. Going forward, I plan to use the treatment every 4000 miles. As per the instructions, I emptied a complete bottle into a half-full fuel tank. Then I drove about 35 miles at low speed. Then, I added diesel fuel as normal.

I read the reviews and was skeptical. My 2011 BMW X5 35d had all the check engine lights on. Followed the instructions. Was able to get the vehicle to regenerate and the problem went away. I now use it on a regular basis. Your results may vary, but I am a convert and will continue to use it. On my 3rd bottle.

This stuff cleared my filter out fast.

Waste of money, 2018 ford f250 , 125453 kilometres, 6.7 power stroke. Followed directions and it did absolutely nothing for my truck, engine light still on and no performance difference.
