It does work for a temporary fix. Price wise is very inexpensive against other brand products that are 30 to 40 dollars or even 50 dollars that guarantee passing emission results. If you use this product for every 5 -10 full fuel tank period or more, I can say you can extend your catalytic converter life, a system with a smooth riding less noise under the hood. If it is every 2 fuel fill up, you will need a new catalytic converter. I have used it on my vehicles the last year and mileage increase has been noted.

1990 Corvette was starting super rough when turning the key to fire up the vehicle. Tossed this in the tank when it was nearly empty and topped it off w 91 octane gas. I don't know the science behind it but this baby fired right up and fixed whatever was causing it to struggle to start. Incredibly impressed.

I just bought a certified used car and noticed the miles per gallon were lower than expected. I put this in the fuel tank, following directions and it cleaned out whatever needed to be cleaned out.

This stuff is awesome. Our Mazda 2 has a P2006 code. We put this in, cleared the code, and drove for 75 miles passed our state inspection (safety emissions). The light does come back on after you turn the car off and back on (after about .5 miles).Another pro is that the car drives a lot better. More power.I highly recommend this.

I can't believe the quality of this product! This is the 2nd time I've purchased it and again I'm amazed by how well my car responds to it. Going to try your entire line next and recommend to family and friends

This stuff really works. Bought it several times. Had a GMC suv that would die when you have it gas. It would start back up, but when you stopped and tried to take off again, it would die. Poured this product in the gas tank, and problem solved. It's been running great.

Needed to smog my truck ran this cleaner through engine with 20 gallons of gas the plugs looked quite clean so this helps remove any build-up on spark plugs hope it also cleaned the fuel system i will run more cleaner again i did not do any thing to truck for 16 years.

It may just be my imagination, but I'm pretty sure my truck had more power and fuel mileage was quite a bit better with this. It's pretty price to use with every tank, but I will get it again if I feel like a need to treat my fuel system again.

This is my first time using this product, but so far I am very impressed. It was very easy to pour in with the attached nozzle. I'm also noticing an increase in MPG with only one use.

I had my car put on a computer for a reading. It indicated that both fuel injectors needed to be replaced. Tried this stuff instead. Fix it! Runs perfect.

I have used this product several times and am generally a fan of Rislone. This did help to increase mileage on long trips on a couple of occasions and it does seem to be a decent value if you take advantage of the rebate. It's a pretty good jack-of-all-trades additive that can also stabilize gas in infrequently driven cars.
