Rislone DPF Clean Diesel DPF, Exhaust & Emissions System Cleaner, 16.9 Fl oz

It cleared code P2002 on my truck. Was quoted around $900 to fix but didn’t need after using this cleaner. Will use their products in the future. Great product

I use this to ensure I have zero def system issues. Works great and is good insurance for keeping codes away.

It is very easy to use and inexpensive insurance. I keep a bottle in my truck, so when I have the opportunity to buy def at the pump, I can protect my trucks system.

gets rids of ash buildup in your DPF

Product works well

I purchased an older vehicle, and thought it would be worth trying your Rislone CAT COMPLETE Fuel, exhaust & emissions system cleaner. It worked wonders in that car. The smoke just flushed right out of it. It runs so much smoother and has much more pep to it. Great product. 🤗

Not sure if it made any difference or not. I didn't have any codes and used the DPF Cleraner product more like a preventative maintenance application. I did use Rislone's DEF treatment product and that worked great.

I was getting a code from my O2 sensors, basicly the difference between the front and back sensors was not enough (Duramax L5P) and this product seemed to help clear that up. I have another code from the fuel pressure sensor and it did NOT clear that one. Im pretty sure that one is a bad connection. Bottom line, do not expect miricles, but in some situations, it seems to help. It smells like amonia so I'm guessing this well help more with catalyst and DEF related issues. Its a little pricey for something thats difficult to prove, but I would try it and see if it helps your situation.

Having a code come up on my instrument panel, read several reviews, threads and then read the company site, googled it and people say it works, only time will tell, easy to use, remember do not put it into the wrong tank or you can make things worse. Will update after a few hundred miles

Snake oil! I tried it since the dealer told me it would be a week before they could even look at my truck. Directions say add 1 bottle to 1/4 tank of fuel. My gage was on 3/4 so I put 3 bottles of the stuff in it. Absolutely no effect. I knew it could not survive combustion and still somehow destroy the ash buildup in the DPF but I was desperate. Waste of money.
