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!

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

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!

A little of everything at once
I'm not sure my car knows what to do with the octane booster but the rest of the additives should help my newer 1.5L tiny turbo stay clean and happy. I'm a little concerned about the summer ethanol mix when the temp here is still below freezing and I expect this should help. It looks and smells like unrefined kerosene.

Cleans injection system
It can be tricky getting it into the gas hole. My '08 6 cylinder Merc seems just a little better after I treat about 15 gallons of gas. My fuel economy is too variable on this car to comment on this aspect. I don't believe any treatment will change the feel in the seat for performance. It may reduce idle vibration and studder during accellerating. The whole idea is keeping a good spray pattern at the injectors. There are other items you should also consider manually cleaning like throttle body. I have always liked their Engine Treatment, so I have stayed with the same brand for fuel nozzles.
