I added this to a full tank before a long drive and the car felt smoother after a few days of normal driving. Super easy to use, no tools or mess. I’ll probably keep a bottle around for regular maintenance.

My truck has over 120k miles, so I wanted something simple to help keep the fuel and exhaust system maintained. Poured it in, filled the tank, and just drove like usual. Easy product and worth adding to the routine.

I like that this doesn’t require taking anything apart. Just pour it into the gas tank and drive. My car seemed to idle a little smoother, and it feels like a smart maintenance step for an older vehicle.

Routine Care Notes

This product is intended for routine maintenance support, not for mechanical diagnosis or repair. Some drivers look for routine care options when dealing with concerns related to catalytic converter efficiency, exhaust-system deposits, or catalyst-efficiency codes such as P0420 or P0430, but this product should not be presented as a guaranteed fix for any fault code, emissions issue, or inspection result.

Catalytic converter clean

A customer’s vehicle was having trouble with the catalytic converter. I wanted to try something new. I found this product and tried it on this vehicle which had the same code for catalytic converter to be replaced. I tried this product Vehicle started smoking and had a real bad smell of burnt. For the price it wasn’t too bad. The check engine light went away it was very effectiveness.

Good value pack

Great value and worked well on my 08 Altima I was fixing up. Seems to have given the engine a boost.

Smoothed my engine

Well I have used this in my last fill up, now several days, and I must tell you that I noticed a smoothness to my engine the first mile. I have no way of checking if it true cleans out the catalytic converter, but it sure has something that is causing a positive effect. I got this product because I own a 2017 Prius V wagon style car and it has gotten a bit rougher running lately. I had the shop install new plugs, had the EGR device cleaned, and all the recommended services done, and still it wasn't quite right. So I got this product filled my tank with gasoline and poured this into the tank when I got home. It sat in the tank overnight. I jumped in the next morning and started my drive and before I got to the first traffic light, I noticed it felt smoother, less engine roughness. Why exactly, I don't know, but this is my experience. It will take many miles to really know if this is a permanent change, but I sure know it works better in my car than regular fuel injection cleaner and it costs about the same. So I think from here on, this is my new additive. Just to mention, my Toyota Prius V has 78,000 miles on it and I change the oil every 3 thousand miles. It had been getting about 39 mpg and now is showing about 41 mpg, so it is a positive in my opinion. Not earth shattering, but I like the improvement just fine. If you have similar issues, I recommend you give this a try and see if it smooths your engine. I will be interested in hearing your comments to see if your getting the same engine feeling I got. Enjoy.

I expected it to smell

Im really unsure about this product.
It says it's ether, but it looks and smells and feels like water.
I think im going to do a little more research prior to using. instructions are included, and are easy to follow.
If it works it'll be a great deal, i just really want to check it out a bit more.
I'll update if my score changes.

1 Bottle did great on less restrictive cats.

I use these type products whenever I get the chance... These products work by superheating your cat and basically steam cleaning the honycomb inside... This one seems to work especially great on less restrictive cats like my pre-2000 dodges, and also did prettty well on my highly restrictive 2010 Beamer, but I'll need to use another bottle on that one... You basically just dump it in and go. Make sure you only have about 1/4 tank or less for full effectiveness per bottle and you'll know when it works due to the steam and often some dark water coming out of your exhaust...

It worked great for me

Used one bottle when I got down to 1/4 tank
Drove till tank almost empty
car 180,000 miles began running MUCH better, smoother, more power, better mpg
Added second bottle and Filled tank then drove 1,300 miles while towing a heavy trailer. Car ran great and still does.
I still have one bottle left and have no need for it right now, maybe in a year or two ?? good stuff
