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

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.

Works good product saved me a $3000.00 dealer repair bill . Be patient, after driving 360 miles the code cleared for the plugged diesel particulate filter

This product cleared a full DPF on a RAM 2500 with two applications, will purchase again for regular maintenance

It’s ok but honestly I couldn’t really tell much difference if any.

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 .

The code went away in one day.Only drove 20 miles local.

3-STARSThis is a review on Rislone DPF Clean, Exhaust & Emissions System Cleaner, 16.9 oz. I am giving this product a 3-star review. This product did not decreased regen frequency from previous additive. This product produced same mileage numbers as previous additive. I noticed a slight increase in mpg of +1. I did not get any engine error codes while using this product.I used 1 bottle of Rislone DPF Clean, Exhaust & Emissions System Cleaner, 16.9 oz. I added the bottle to 8 gallons of fuel.No check engine lights came on. Vehicle showed no adverse affects from additive.Regen mileage interval with NO additives was 384 miles after receiving vehicle from repair shop. Mileage between regens decreased from 384 miles (baseline) to 323 miles. A product used 3 tanks before, dropped mileage interval below baseline mileage. This product gave my vehicle a decrease of 61 mileage between regen intervals compared to baseline numbers. I had previously used Liqui-Moly Diesel Purge 3 tanks prior to this product. Rislone DPF Clean, Exhaust & Emissions System Cleaner gained 0 miles over previously used Rislone Hy-Per Diesel, relating to regen mileage intervals. I'll base the review on increase of +1mpg. This product showed no improvement in regen interval length compared to other Rislone Hy-Per Diesel product. Regen period slightly shorter, but removed less soot. I did not notice any improvement in power.Driving Notes:30 miles driven during regeneration cycleSoot down to 12 grams.EGTs = 556F temperature, normal highway drivingEGTs = 692F temperature during regeneration cycleInjection quantity at idle at baseline=9mmInjection quantity at idle after Rislone DPF Clean, Exhaust & Emissions System Cleaner=8mm#1 #2 #3 #4 #5 #6 #7 #8Injector balance at baseline: -0.5, 0.1, -0.2, 0.9, -0.6, -0.1, 0.0, 0.4Injector balance after additive: -0.6, -0.2,-0.3, 0.5, -0.9, -0.3, 0.4, 1.2Less fuel being used at idle.Exactly same from previous additive.Regen down to 12 grams.No negative affects.My review is based on product efficiency, any damages to vehicle, check engine lights turning on or off, ability to clear engine codes (if my vehicle has any check engine lights), increase or decrease in mileage, and increase or decrease in regeneration mileage intervals. I will not use price as a factor. You will have determine if product is worth the cost. These products may or may not save you costly repairs or replacement. I cannot determine if these products can or will damage your vehicle.My vehicle has no check engine light or error codes. My vehicle is in good working order with no current issues during this review. My vehicle has over 200,000 miles. This is a stock vehicle, with a stock (OEM) factory tune installed. Just prior to this test, my truck was not performing a regen cycle. Repairs were done which included a new 9th injector, new DPF pressure monitor. The pressure monitor measures pressure before and after the DPF filter. The difference in pressure allow computer to estimate how much soot has accumulated in the DPF filter. A force regen was also performed on my vehicle and a passive regen performed before I received my vehicle from repair shop. Vehicle is performing as it should.Test drive is relatively the same and consistent. 49.5 miles one way, with a drive time of about 56 minutes. There is a gradual 1129 foot elevation gain one way and 1129 elevation loss the opposite way. There is some surface street driving, some freeway driving, and most of drive is highway.Hope this review helps. I will be writing more reviews on other diesel additives. I have some data from other additives for comparison listed below. Most products seemed to help and a couple seemed to worsened DPF performance during testing.You should not compare the towing data for comparison. I have just added it to show that towing will change data. Towing will increase exhaust gas temperatures and should make the DPF more effective. My regen mileage intervals increased, decreasing regen frequency, while towing.There are many factors that affect the DPF performance. The factors that I noticed (on my vehicle) are outside temperature, humidity, and EGTs. Lower temperatures decreased DPF performance. Higher humidity decreased DPF performance. Higher outside temperatures and lower humidity seem to increase DPF performance. Higher EGTs such as towing increased DPF performance.Regeneration Interval Mileage Comparison of Different Additives:baseline (no additive), 384 miles between regeneration intervalsArchoil AR6200 Fuel Treatment, 391 miles between regeneration intervals,+7 mile increase from baseline, +7 mile increase from previous additive(none, baseline)Wynn’s DPF Regenerator, 462miles between regeneration intervals, +78 mile increase from baseline, +71 mile increase from previous additiveSeafoam (high dose), 504 miles between regeneration intervals, +120 mile increase from baseline, +42 mile increase from previous additiveNitrox Clean Cat Diesel, 324 miles between regeneration intervals, -60 mile decrease from baseline, -180 mile decrease from previous additiveArchoil AR6500 pulling trailer in hot weather (not same comparison) , 1075 miles between regeneration intervals, +691 mile increase from baseline, +751 mile increase from previous additiveNitrox Clean Cat Diesel 2nd try, 402 miles between regeneration intervals, +18 mile increase from baseline, +78 mile increase from previous additive(Nitrox Clean Cat Diesel)Liqui Moly Diesel Purge, 265 miles between regeneration intervals, -119 mile decrease from baseline, -137 mile decrease from previous additiveWynn’s Turbo Cleaner, 298 miles between regeneration intervals, -86 mile decrease from baseline, +33 mile increase from previous additiveRislone Hy-Per Diesel, 323 miles between regeneration intervals, -61 mile decrease from baseline, +25 mile increase from previous additiveRislone DPF Clean, 323 miles between regeneration intervals, -61 mile decrease from baseline, 0 mile difference from previous additiveArchoil AR6500 pulling trailer in hot weather one way, cooler temps coming back(2nd trip, different route) (not same comparison), 680 miles between regeneration intervals, +296 mile increase from baseline, +357 mile increase from previous additiveStar Review Legend1 star: Made check engine light turn on or trigger error code(s)2 star: Causes no check engine warnings and no engine error codes. Mileage worsened or DPF regeneration intervals decreased in mileage.

I followed their directions and added one bottle to a half tank of diesel in my Jetta TDI. Ran about 2,000 mi and unfortunately it did not work.So I filled the tank to half again and added another bottle of this snake oil and the same results. It did not work.So ignore the YouTube videos on this because its nothing more than snake oil!!!
