The Most Complete Formula Available: Rislone Gasoline Fuel System Treatment

Over time, poor or questionable gasoline can foul up your car’s fuel system. It’s important to keep this critical system clean so your car can work at peak efficiency and power. Rislone Gasoline Fuel System Treatment is made to improve the quality of gas by increasing its cleaning ability, adding lubrication, removing contaminants, reducing spark knock, and helping to prevent the fuel from going bad. It’s far more than your average fuel injector cleaner — it’s one of the most awarded and popular fuel system treatments on the market. It’s even won a PTEN (Professional Tool & Equipment News Innovation Award – a difficult task for a fuel treatment product.

One dual-cavity bottle contains the same amount of additives equal to a bottle of regular fuel injector cleaner, upper cylinder lubricant, fuel stabilizer, gas dryer, gas treatment and octane booster. In other words, this is one powerful bottle. This formula increases power, performance, mileage and saves you gas by cleaning and lubricating the complete fuel system. It also happens to be our most popular fuel treatment worldwide.

One of the key factors to getting the most performance and economy out of your gasoline engine is to maintain the quality and cleanliness of your fuel system.

  • “Just wanted to say thanks. You see, I read a Facebook post back in November or so where someone mentioned the mileage improvement that could be obtained through the use of your Rislone fuel injector cleaner. I didn’t think much of it, in fact I kind of thought there is no way a little bottle of magic potion can make much of a difference, especially since my Jeep is relatively new.

    A little background: I have a 2012 Jeep Wrangler Unlimited. It just turned 10,000 miles so still pretty much new. Of course within a few weeks of purchasing it I had added about 300 pounds and a lot of roll resistance with larger tires, bumpers etc. I started tracking my mileage and it was dismal (all data points were during winter, December to early April):

    12.36 mpg, 11.76 mpg, 12.32 mpg, 12.87 mpg, 12.8 mpg

    I pretty much do all city driving but this was ridiculous. So I decided to try your product. The results were good enough that I felt compelled to write this email. First tank 13.38 mpg, I’m thinking not bad but is it worth it? Then:

    13.94 mpg, 13.85 mpg, 14.02 mpg 15.14 mpg (drove a little on the expressway)

    Other than the last data point it was all city driving. So basically I’m converted, I don’t think I’ll ever stop using this stuff. Thanks for putting out a product that lives up to the hype.”

  • “Hi all, I own a 2001 Subaru Outback station wagon. It has 190,000 miles and I wanted something to add to my fuel tank to give it more "Zip" while driving to work.

    I saw your gas treatment additive at Wal-mart so I thought I'd give it a try. I added it to a full tank of gas and after a short time I noticed my car seemed to accelerate quicker and run smoother. I later saw your Engine Treatment Concentrate and thought I'd try it as well. I was so happy with the added pick up, smoothness while accelerating during mountain driving and the overall ease of driving with your products. I am looking forward to seeing a change in my fuel economy. I'm sure it will be noticeable. I've had numerous chances to tell friends and co-workers about your products. I plan on using them on a regular basis for my vehicles overall care. Thanks for a great product that really works.”

  • “Believe me when I say I think a lot of fuel additives don't do much. This stuff is different, and I felt the difference right away, and I noticed my 2013 V6 Camaro has better performance in the summer heat than usual. This is a product that actually works in a sea of products that don't. Thanks!”

    B. Wesphal - Atlanta, GA
  • “I noticed an MPG drop when the "winter" gas started hitting the pumps. A salesman at AutoZone suggested I try Rislone Fuel Treatment, and it really helped with startup, noise and acceleration with my 2012 Audi A4 (turbo). Good stuff. I use roughly every oil change.”

    T. Hahn - San Diego, CA
  • “I tried the complete gasoline treatment in my Mercury Grand Marquis and noticed a smoother running engine. It really works.”

    S. Peters - Chicago, IL
  • “I applied the product after leaving my car running (Chrysler 300 Touring) for 20 minutes. Then I test drove it & it ran smooth. Test drove it for a 2nd run, & it ran smooth. Truly an unbelievable product and hands down it's the problem solver.”

    Jay - Erie, Michigan
  • “I don't know what this product has inside but it works. I have a 2002 Ford Explorer with 114,000 miles that was idling terrible, shaking and hardly staying alive. Then decided to put some kind of injector cleaner and went to Walmart and the first product that hit my view was the Rislone, what the heck, let me give a try, that was two days ago, today is Sunday and the idling is by far much better and smoother and with somewhat better power. I hope it stays this way. Where I live the gas is poor quality whatever brand, so I was thinking of trying also the Rislone oil treatment. So is a good product that I have seeing for many years around...congratulations...”
