Molecure Catalytic Restore Emission Treatment – Catalytic Converter Cleaner & Oxygen Sensor Fuel Additive – Reduces Carbon Buildup – 12 oz Bottle, Treats Up to 20 Gallons

I added this to a full tank as directed and noticed smoother acceleration and improved throttle response after driving for a while. The engine feels cleaner and quieter, and an emissions-related check engine light showed improvement. It's very easy to use—just pour and drive. For the price, this is a great preventative maintenance product and a good option to try before spending money on costly catalytic converter or sensor repairs.

The product does what the label states. Added this to a full tank of gas, and within a quarter of a tank I was already able noticed better acceleration and less hesitations, especially when the car is cold. I'm thinking that using this regularly might help my car make another couple of years.

I have used products from this manufacturer in the past and have been satisfied. With this in mind, I decided to try this particular product to see if it produces the effects advertised. It does seem to help with starting and running more smoothely at idle. I thisnk this is a good producr to use on my higher mileage vehicles, which is all I own actually. What I am hoping to see in the near future is a better throttle response by having the catylic converter cleaned out somewhat.

Great Product. I have purchased this a few times for each of my different vehicles and it makes a difference. Seems to clean out the engine a make it a bit smoother. I will continue to buy this . For the price its a good deal. Just try it. It works.

Waited till tank was down to a little less than ¼ tank per directions. Ran up and down the interstate at highway speeds 26 miles. It ran great peppy. Reset the check engine light for O2 sensor after filling up with gas. The light hasn't come back on. Used on a Toyota Sienna van with 305,000 miles. Been a work horse for us and this additive worked so far. O2 sensors were changed at 230,000 miles. Original cat converter on it with no blockages etc. Worked for me. Recommended

used the Molecule Catalytic Restore Emission Treatment in my SUV. I added the full 12 oz bottle to a near-full tank as directed.After about half a tank of driving, I noticed smoother acceleration and improved throttle response. The engine felt more responsive, especially at highway speeds. Fuel economy also improved slightly compared to the previous two tanks. For the price, it's a solid option if you're dealing with minor carbon buildup or just want to maintain your catalytic converter and oxygen sensors. I'll likely use it again as part of regular maintenance.

I was pleased with how quickly I received this item, how easy it was to use, and the noticeable improvement in my vehicle performance. I felt a smoother ride, enjoyed a better fuel economy, and haven't seen any engine lights since using this product. I will definitely use it again to extend the life of my family vehicle.

One of the best Fuel System Cleaner I have ever used, I had 02 Sensor alarm, and it clear it after first use. This came highly recommended by my family mechanic who suggested this would be cheaper to try then buying new oxygen sensor. I am glad I found this product.

Worked immediately in wife's car! Was having issue with Check Engine light, appears to be off now. Also feels like the car is running less sluggish.

This is another one of those products where you just don't really know if it's going to work until you've put mileage on a vehicle. The only way to really know if it works is if you have a DTC indicating a catalytic issue or you run the full bottle and you put a borescope down a spark plug hole. Of course, there's also did you fail your last emissions test and you passed it this time after using this product? My state does not have emissions testing. But I have honestly no reason to believe this product does not work.
