Rislone Complete Fuel System Cleaner for Gasoline, Ethanol, and Hybrid Vehicles

[This review was collected as part of a promotion.] I bought this today and used it immediately. Great price and great product! Gas treatment, injector cleaner, octane booster, water remover and fuel stabilizer! I noticed I had better mileage and car responded really well when accelerating

I caught myself down on my luck. One day, I was just scrolling through, minding my own business in AutoZone, and looked over and this just popped out. I said to myself, "Hey, you should try this." I tried it. I'm a new man, and so is my brother.I caught myself down on my luck. One day, I was just scrolling through, minding my own business in AutoZone, and looked over and this just popped out.

[This review was collected as part of a promotion.] My F150 was running a little rough. I added a bottle of the One Tank Deep Clean. It was amazing the difference it made. After about 20 miles, I could definitely tell a difference. My truck started to really perform as it should. It feels like I gained 10 horsepower. WOW. Definitely would recommend.

I bought this fuel system cleaner to add to my fuel for regular maintenance. So far I have no complaints at all.. I've received better gas mileage. Smoother idling and more horsepower. I will definitely be using this product with every oil change as suggested

[This review was collected as part of a promotion.] I rely on Rislone 8-in-1 Tune Up Fuel System Cleaner to combat the effects of ethanol in my 1979 Lincoln Continental with over 106,000 miles on the original engine. In doing so, I also enjoy the other benefits of easy starting and excellent acceleration.

Using the Rislone Fuel System Cleaner is good hygiene for the engine — reducing carbon deposits, cleaning the fuel injectors, and keeping everything running smooth and efficient. After just one treatment, I noticed improved fuel economy and improved throttle response. It's simple to use, works exactly as promised, and gives me peace of mind knowing my engine is cleaner and healthier. Highly recommend for anyone who wants to keep their car performing at its best!

[This review was collected as part of a promotion.] I’ve tried a few fuel system cleaners before, but Rislone Complete Fuel System Cleaner 4702 really stands out. After using just one bottle in a full tank, I noticed smoother acceleration, less hesitation, and overall better engine performance. What I like most is that it’s truly an all-in-one product. It doesn’t just clean injectors—it also helps remove carbon buildup, improves fuel quality, and even adds lubrication to protect engine components.  That’s a big plus compared to other cleaners that only do one thing. Within about 50–100 miles, my car felt more responsive, and my idle smoothed out noticeably. It also helped reduce some minor engine noise, which was a nice bonus.  Another thing I appreciate is how easy it is to use—just pour it into your gas tank, and you’re good to go. No complicated steps or multiple treatments needed. Overall, this is a great product if you want a quick and effective way to clean and maintain your fuel system. I’ll definitely keep using it regularly. Highly recommend if your car feels sluggish or hasn’t had a fuel system clean in a while.

[This review was collected as part of a promotion.] I have a Chevy cruise that was constantly bogging down and not running right my buddy suggested this product to clean out my fuel injectors to see if that was the issue. I used a bottle of this and haven't had an issue since.

Please read the SDS and google the CAS numbers before putting this garbage in your car!! They claim 8 different fuel cleaners in one bottle but show only 2 ingredients on the SDS and the largest amount is a base for skin cream!! Before you waste your hard earned money and ruin the second biggest expense in your life, do a google search on the ingredients so you really know what snake oil is!!!
