This has given me an additional 2 MPG, which is unheard of (with my driving, at least). Engine sounds and feels more smooth. I think this is quite effective at providing a cleanse to your fuel system. I was having issues with starting for a while- now (after about a half tank running) I have no issues at all. Thanks!

I've tried many different additives and this is by far one of the best, if not thee best. As soon as I put it in the tank and fill up gas, I notice the difference within a mile or two. The engine gets quieter and rough idle becomes non-existent. Other additives have nothing on Rislone!

Works great but make sure you fill your tank up before pouring it in.

This is my favorite fuel system cleaner brand. Good value for the price. Same as what I'd buy in the store

I used the oil treatment and had great results quieting my engine noise on my 14 kia forte with 120k. Decided to try the fuel treatment to help with rough idle. This worked just as good as the oil treatment! My car is now as quiet as when it was new, barely hear it running standing right by it! This treats 22 gallons but my car only has about 10 gallon tank. Tried to pour in half bottle but it didn't come out even so I dumped the whole bottle in and filled up the tank. Within first 1/4 tank it was smooth as a kitten. Ran to 1/2 tank then filled up again to get it to intended strength and get more our of the bottle. This stuff works better than any of the other stuff I have tried. Gumout, Lucas, techron only gave 1/2 the results I got with this. This will be my go to and recommendation from now on!

I was getting the engine light on in my car and after scanning for codes I got the impression that I need to change my oxygen sensors but after pouring this into a 1/4 tank and driving it for about 30 miles the error went away

My vehicle is an 2010 Ford Taurus, which I purchased Brand New. Mileage is now 79,700 and still runs efficiently and strong. Rislone Gasoline Additive has made my car quieter and added more power.

Once every 6 months I deep clean all my cars fuel systems. Some I can feel a big difference, my Ram 1500 Hemi, once I run tank about 3/4 down I can feel a boost in power(Is not in my head), I have raced cars etc and when whatever it cleans happens, truck feels like it had a tune done. Most likely it's the injectors cleaned causing the power increase and smoothness, but I notice it right away. I have not noticed a boost in my Camaro SS, doesn't mean it isn't helping, but I did not notice anything.

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.

I use it regularly on a 2012 Honda Accord and a 2020 Toyota Corolla. I get great mileage and smooth engines. It also keeps my Honda's engine so clean that I never failed a smog check. This is the best additive money can buy.
