Rislone® 4744-4PK DPF Clean™ Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 oz, 4-Pack

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.

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 .

Been using in my 2020 Ram with 6.7 Cummins. Seems to help shorten the length of time engine spends in "regeneration mode"

Excellent product

This product works very well but you have to follow the directions or it does not work I bought three .bottles

I had the check engine light come on. Checking the code, it said in essencethat the SCR cleaning was below the threshold. I added a bottle to half a tank of DEF and followed the directions on the bottle. No codes since then (1 month).

This product seems to be working. Had to use 2nd bottle to get the code off for the exhaust. Been off for 3 days now. Will use a bottle at every oil change (5,000 mi). THX

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.
