Rislone Hy-per Fuel Fuel Injector Cleaner Concentrate, 6 oz

I was skeptical about this particular fuel additives. Normally I don't use what's recommended (especially my so-called mechanic friends) but in this case for my 2017 Honda fit it worked phenomenally. My fit was idling rough and had some hesitation at stoplights. I tried a bottle of Rislone Hy-per Fuel Injector Cleaner and noticed a difference within about 20-30 miles. The idle smoothed out significantly, and the acceleration feels much crisper without any stress. Definitely brought peace to my mind! I would highly recommend this in a heartbeat!

Put in about 1/3 of a bottle cranked it some to get the mixture into the carburetor let it sit overnight. Got it to start the next day ran rough for about 5 minutes then started to smooth. Only brand of the 6 options at the auto parts store that listed "carborator" out and run good.

My vehicle was seeming sluggish so I used the injector cleaner and there was a noticeable change pretty quick. Great product. Definitely will buy again.

[This review was collected as part of a promotion.] I've purchased Rislone treatments for many years and many cars. It always does what it's supposed to do. I highly recommend any and all of their automotive additives.

[This review was collected as part of a promotion.] I bought this a couple of days ago trying to get better gas mileage and I used it just how the instructions intended and when I completed it and filled my tank back up I noticed on my day to day driving from work my car records my gas mileage and it went up considerably!!!

I bought this item and it's one of the best investment I've made for my vehicle. The quality is wonderful for the price I bought it for. Since I've bought it my vehicle has had no problems and runs and drive perfectly.

Noticed a little less MPG even after oil change, This improved it by a couple MPG, cleared out rough idle as well.

[This review was collected as part of a promotion.] Bought this yesterday, so far so good!!! Will buy again.

When I first bought it and used it my check engine light went out for awhile but it came back on and I bought it again and have used it but the check engine light is still on
