Hy-Per Fuel Complete Gas System Cleaner By Rislone Review

The 2015 Rav4 I was driving was having a hard time keeping travel speed on the Bear mountain until I used this product Thanks for attention.

Always was a great additive.Used a scope to look down my plug hoes and the piston crowns were squeaky clean! This product may not be readily available in all regions!

Review is for:Rislone Hy-per Fuel Complete Fuel System Cleaner Gas8 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…

I'm restoring a 1993 Bronco (fuel injected) that has been in semi-storage for several years, but it was run occasionally. I changed the filters and the stale gasoline (was treated with SeaFoam), but it was still idling a bit rough with an occasional miss. Having bought the Bronco new, I also recall having other fuel system issues that were stubborn, even with the Ford Dealer working on it. OK, time for the "Mechanic-in-a-Can" approach. I added this treatment, the whole bottle, to a bit under a…

Excellent product. Been using for years. It will improve cars performance. It will eliminate any wateri n fuel system. I use once a year in a car that is not driven in winter. I highly recommend.

Brand new truck. Got a tank of gas, truck started to stutter badly and would cut off. Poured this product directly into the fuel fill. Let the truck idle in the driveway and within a few short moments, the stutter was 100% gone and the foul exhaust smell from the bad gas went away. This stuff is a must if you suspect water in your gas, or bad gas from a vehicle not driving in awhile. Try this first before panicking and going to a costly mechanic. This stuff really does help with bad gas and…

Seemed to make all the problems worse. Used in the winter on a 2009 Toyota Matrix with an almost empty tank of gas, then filled up (like the instructions say). Car had more trouble starting, idled much less smoothly, definitely didnt improve acceleration or anything else.Would not buy again.

This stuff is NOTICABLE! I put it in my grand cherokee with 362,000+ miles and noticed quite a difference in idle smoothness, highway passing and overall hummm of the engine. Believe me, I know this vehicle and have owned it since 26k miles / 1997 and can tell any type of difference about 'er. I will buy this stuff again.

I've never used anything like this before but I'm pleased I finally gave it a try. I used it in my hot rod 2003 WRX Subie (highly modified/ produces 480+ hp) and it quieted the engine noise a bit but it really made a difference in my 2011 528i BMW. I've had a problem with an engine warning alarm coming on when I really stepped down hard on the gas pedal. This happened twice in the last two months. I added a bottle of Rislone 4700 to a full tank of gas, and I haven't had any more problems. I…

I used this product in a 2007 Honda Accord , with a I-4 , VTEC , engine. Miles per gallon had dropped to 23 city 26 highway The car has 247,000 miles on it. I added this to a full tank. I then drove towards Atlanta on I75 @ 75 miles per hour. When I filled up at Half tank left Highway mpg had jumped to 32. Like when the car was new. I improved starting. My main goal was cleaning the fuel injectors. When I returned home I rechecked the car with the computer scan tool. And both long term and…

My car was stuttering/shuttering and stalling (especially when going uphill). The mechanics at the dealership recommended to drop the fuel tank, remove the gas, scrub the tank and replace the old fuel pump - which would cost $700-800 for all the work and parts. It was an old car and the cost of the repair was between a third and half the cost of the car. I used this and filled up the tank and the issue was almost resolved. I used a second dose and the problem was gone.It lasted long enough for…

This works as advertised. I used this at the start of a 1,300 mile road trip and it pushed out an additional 2 MPG on my car, over the course of the trip I easily saved money over the cost of this item. The effect wore off after 3000 miles unfortunately.

I commute 15 miles each way to work five days a week in my VW GTI. This fuel cleaner is one of the best that I’ve used. There is a noticeable difference in exceleration and power. I try to use it with every other gas refill when my tank is about half empty. If I don’t use it I’m able to tell the difference in performance. However, I can’t really tell the difference in gas mileage consumption because I’m kinda heavy on the pedal on the highway. (I’m use to autobahn driving) As I’ve notice, this…

The fuel cleaner is effective for cleaning fuel systems. I initially used one bottle and had to use another bottle after a month to get the results I need.

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…

Worked great on a sluggish generator and atv. I neglected them carbs very dirty but they ran poorly. After 20 minutes in gas tank the idle improved and starts easy.

I drive a Jeep Wrangler, & recently had the EGR valve replaced and 2 O2 sensors. My mpg at that time went to 6. mpg. in a very short time. AThe EGR valve became sticky, and I am not willing to pay a high amount again to repair it. I have low mileage, and feel this is a curse, which I must shake. hahhaI bought this and put it in as directed to do, filled up the Jeep, drove no more than about 100 miles, and.I am shocked my mpg went up from .4 to 12 mpg as of this afternoon when i checked it. I am

my gas milages TANKED after using this… i normal use lucas products but i was referred to this via amazon it had decent reviews… i went from getting avg 26mpg on the freeway too 14.9mpg…? wtf

I'm not one to review, but i have a 1990 boat with a GM V6 engine that was stalling out at idle, in spite of running fine at speed. Adjusted idle screw, it still would die. Changed fuel filter, spark plugs, wires, dist cap, ran much better but still dying at idle. Used spray cleaner on throttle body and carb, no change. Finally realized the 30 gallon gas tank was probably a combination of 1 and 2 year old gas stored over the winters, in spite of having added stabil/seafoam. Duh. my mistake…

My car is a 2012 honda civic with nearly 300,000 miles. It started having problems starting and when I took it into the shop they told me the alternator was bad and replaced it, but a few weeks later it started having the exact same issues. I do trust my mechanic so I think the alternator was part of the problem, but I was panicking that I was looking at another massive repair bill. My research suggested the fuel injectors could be the problem.I tried a different brand of fuel injector cleaner…
