Features

  • Increases power, performance, mileage and saves fuel by not only cleaning the entire emissions & exhaust system, but the fuel system too.
  • Regular use every 5,000 miles tunes-up the fuel, emissions and exhaust system keeping clean and prevents excessive exhaust regeneration and the CEL light from returning. Clears P242F & Other OBD Codes.
  • Will not void manufacturers new vehicle warranty. Specifically designed and safe to use on vehicles with DOC catalytic converters, DPF particulate filters, SCR selective catalytic reduction devices, or DEF systems.
  • Works with all ULSD (Ultra Low Sulfur Diesel), regular dieseloff road for USA, biodiesel blends B2, B5, B20, DI (Direct Injected), common rail another name for DI, IDI (Indirect Injected), TDI (Turbo Direct Injected), and turbocharged engines.
  • Lowers ignition temperature inside DPF to burn soot and particulate matter, ideal for infrequent highway regeneration intervals.

Description

Rislone DPF CLEAN Diesel DPF, Exhaust & Emissions System Cleaner has high- performing detergents and heavy duty cleaning solvents that effectively scrub and remove contaminants, soot, carbon build-up, and oily residue from the fuel injectors, combustion chambers, turbo, EGR, diesel oxidation catalyst, diesel particulate filter and the exhaust system. These along with other active chemical agents, react with the gases created in the combustion process to remove the remaining inorganic deposits. This process restores their function and with regular use maintains efficiency. As fuel is burned, contaminating byproducts are created that are circulated throughout various vehicle systems. These systems are designed to be able to handle this process during most normal engine operation. However, the use of poor quality fuel, short driving distance, cold weather, improper maintenance, and component failure can greatly increase the amount of contamination and deposits created inside these systems. Such factors can cause increased exhaust emissions, reduced fuel economy, lost power & performance, drivability issues, engine overheating, hard starts, check engine light illumination and premature engine wear. NOTE: This bottle is designed to work in ALL diesel tanks including those with misfuelling devices. INSTRUCTIONS: Light Duty Diesel (up to 40 gallon fuel tank), add entire bottle into approximately 1/4 full tank truck or large SUV, (1/2 full tank for car or small to mid-size SUV) of diesel fuel. Drive vehicle (ideally in a lower gear than you normally would) for 20 to 30 miles. Continue to drive vehicle normally and fill tank with diesel fuel. For vehicles with extremely dirty filters, a force regeneration may now be initiated. If light is still on, second application may be required, or mechanical attention is needed. Medium and Heavy Duty Diesel (40 to 80 gallon tank) use 1.5 bottles. 81 gallons and larger use 2 bottles.

  • Does what is says!
Size: 16.9 Fl Oz (Pack of 1)
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. ... show more

  • This product REALLY works as advertised
Size: 16.9 Fl Oz (Pack of 1)
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!!! ... show more

  • Worked on my 2014 VW Jetta Sportwagen TDI
Size: 4 Pack
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. ... show more

  • Solved the problem
Size: 16.9 Fl Oz (Pack of 1)
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).
