Quality
I could tell a big difference after I used Rislone on my 15 yr old car. It ran alot smoother. EXCELLANT PRODUCT. I think it worked better than Seafome.

The best.
This is one of the few additives I've used that actually works. I could feel a difference in both cars Sienna and CX-9

Use it more than once. The first tank could reduce fuel consumption while it cleans.
The first time I used it on my 2025 Landcruiser with 2000 miles on it my fuel consumption dropped from 21.9 to 19 mpg. I was shocked but rode the tank out. Two tanks later I put a second bottle and I got 23 mpg. Same driving. Even newer cars need cleaning and I can feel a nice acceleration improvement and it runs very quietly.

Smooth Running, Noticeable Results
This fuel system cleaner really makes a difference — smoother acceleration, better performance, and great value in a pack of four. Easy to use and keeps the engine running at its best!

This stuff works! Period
I've used Rislone products for years, in my Nissan, Jeep, 56 Chevy classic, & my Corvette 645hp muscle car classic from the past, & I have had nothing but good experiences with them. You can't go wrong with Rislone! Update, it's so good, I'm ordering the 4 pack again, 7-18-26 especially for my 1956 Chevy 350ci, & my 2002 Corvette Z06, 645 horse, muscle car, but I'm going to drop a bottle content into my Jeep Wrangler, & Nissan. Love the stuff.

Did not cause anything nefarious, but also no lasting results
Review is for: Rislone Hy-per Fuel Complete Fuel System Cleaner Gas 8 y/o vehicle felt like sluggish acceleration (especially uphill under light load) but otherwise running fine and recently serviced. Figured the price was right and would give product a shot in a full tank of gas. Reset trip meter to accurately check MPG. Acceleration seemed to improve slightly, but MPGs went down measurably. Things back to previous state after a few hundred miles. TLDR; Would not buy this again unless I was driving a much older and less maintained vehicle.
