## Overview

Rislone Hy-per Diesel Complete Fuel System Cleaner is a premium all-in-one additive that cleans injectors, valves, and combustion chambers while boosting cetane levels and fuel economy. It stabilizes fuel, prevents gelling, lubricates critical components, and reduces emissions. Compatible with all diesel engines and fuels—including ULSD, biodiesel, and off-road diesel—this treatment enhances performance, protects fuel systems, and ensures smooth cold starts, making it a must-have for diesel vehicle owners seeking peak efficiency and reliability.

## Description

Rislone Hy-per Diesel Complete Fuel System Treatment improves the quality of Diesel fuel by increasing its cleaning ability, adding lubrication, removing contaminants, fighting corrosion, and helping to prevent the fuel from gelling & going bad. This one dual cavity bottle contains the same amount of additives equal to a bottle of regular injector & complete fuel system cleaner, anti-gel cold flow improver, fuel stabilizer & conditioner, Cetane booster & diesel treatment, ULSD sulfur substitute, and UCL pump & injector lubricant. Simply put, it is the best all in one diesel fuel additive money can buy. Works with ALL: Ultra Low Sulfur Diesel (ULSD), Regular Diesel, Biodiesel Blends, Direct Injected (DI), Indirect Injected (IDI), Turbo Direct Injected (TDI), High-Pressure Common Rail (HPCR), and Turbocharged Engines. Use with ALL: BlueTEC®, Cummins®, Duramax®, EcoDiesel®, Navistar®, PowerStroke®, TDI® CleanDiesel and many more. Heavy Duty Top-Lube improves fuel lubricity to protect fuel injectors and pumps from wear, especially in todays severely refined diesel fuels. Cold Flow Additives inhibit wax crystal growth, reducing fuel pour point and cold filter plug point even in harder to treat diesel fuels. Reduces CFPP up to 20°F (5°C). Fuel Stabilizer Antioxidant retards oxidation, reduces sludge formation, inhibits fuel decomposition and provides fuel stability for storage. Cetane Improver raises the Cetane number of diesel fuel to improve cold stars and reduce misfires, warm-up time, black exhaust smoke, and emissions. Typical numbers show a 1 to 2 point increase in Cetane Number CN per ASTM D613 engine test. Dual clean-up and keep-clean formula removes injector deposits, prevents and estores lost power and improves fuel economy. Real world testing shows an average fuel economy increase of 7.3% and an 87% power recovery with regular use. Includes a specially designed spout which allows it to be poured into all fuel tanks, including those with misfuelling devices.

Review: Absolutely works as advertised! - My 2015 Ram 3500 6.7 Cummins was running really rough after a fuel filters change. At idle there was a regular pulsing swing from 600 rpm to choking. It was clearly being starved of fuel. I put on brand new pair of Fleetguard filters after the new Mopar filters started throwing an injector rail code and put me in limp mode a couple times. The Fleetguard filters cleared the code and no more limp mode. It ran better but something was still wrong. I figured something was clogging the injectors? Let me try this stuff. On the bottle it says it works right away but may need another bottle in severe circumstances. This product cleaned/cleared up that rough pulsing idle within 2 minutes and my 6.7 is running free again! I highly recommend this product!
Review: Best for my TDIs - Tried all the fuel additives for my TDIs. So far this is hands down the best. Keeps those codes at bay if used properly. So far so good!!!!

## Questions & Answers

**Q: 6.0 power stroke is better but not 100%. Will it damage engine by running a few consecutive treated tanks?**
A: 6.0 Power Stroke is an oil additive.  Rislone 4740 is a Diesel fuel additive.  Have been using it for a Yanmar engine for many years without problems.

**Q: Can be used for a diesel electric generator?**
A: This diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines. We would recommend that you use the amount stated on the directions depending on the tank capacity of the generator. If the tank is 10-18 gallons we recommend a half of a bottle. If over that you may use a full bottle.

### ⭐⭐⭐ Seemed to make engine run smoother and quieter.
*by S***N on November 2, 2024*

3-STARS This is a review on Rislone Hy-Per Diesel Complete Fuel System Cleaner, 500ml. I am giving this product a 3-star review. This product did decreased regen frequency from previous additive, which suggests that it may have cleaned the DPF to some degree or enhances combustion action to burn cleaner. No changes to fuel mileage from baseline were noted. I did not get any engine error codes while using this product. I used 1 bottle of Rislone Hy-Per Diesel Complete Fuel System Cleaner, 500ml. I added the 500ml bottle to 32 gallons of fuel. No check engine lights came on. Vehicle showed no adverse affects from additive. So far, this is the only product that seemed to have made the engine run quieter and smoother. 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 2 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 2 tanks prior to this product. Rislone Hy-Per Diesel Complete Fuel System Cleaner gained 25 miles over previously used Wynn’s Turbo Cleaner, relating to regen mileage intervals. I'll base the review on regen mileage gain on previous mileage (not baseline). I did not notice any change in fuel economy. I did not notice any improvement in power. Driving Notes: 35 miles driven during regeneration cycle Soot down to 4 grams. EGTs = 556F temperature, normal highway driving EGTs = 692F temperature during regeneration cycle Injection quantity at idle at baseline=9mm Injection quantity at idle after Rislone Hy-Per Diesel Complete Fuel System Cleaner=7mm #1 #2 #3 #4 #5 #6 #7 #8 Injector balance at baseline: -0.5, 0.1, -0.2, 0.9, -0.6, -0.1, 0.0, 0.4 Injector balance after additive: -0.9, 1.2, 0.1, 1.0, -0.8, -.04, -0.3, 0.0 Less fuel being used at idle. Decreases in regeneration intervals, +25 miles from previous additive. Regen down to 4 grams. No negative affects. Quiet operation and smooth idle. 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.

Mileage worsened or DPF regeneration intervals decreased in mileage. DPF regeneration process worsened. 3 star: gained less than 50 miles in regen mileage interval, or slight increase in mpg. 4 star: gained more than 50, but less than 100 miles in regen mileage interval, or +2 mpg increase 5 star: gained more than 100 miles in regen mileage interval, or +3 mpg increase.
