MotorKote Catalytic & Exhaust Treatment provides the care your catalytic converter and exhaust system need to ensure peak performance, lower emissions, and pass emissions tests with confidence. Review: This actually works when their competitor didn’t - Worked perfectly, 2010 F150 5.4 with 244,000 miles. Yes, replaces the engine 20,000 ago but the exhaust system, including O2 sensors are all original. I’ve tried other cleaners with no success. Decided to try this, and because the truck had a 32 gallon tank, I purchased the 6 bottle deal. (Instructions say 1 bottle per 16 gal gas) 1st tank had 3/4 of a tank when I added the first 2 bottles. 2nd tank, added 2 bottles when I filled up. 3rd tank, added last 2 bottles when I filled up. Gas gauge hit 3/4 of a tank and the check engine light went off. Reminder, I HAD 244,000 miles of build up on stock exhaust parts, including sensors. Worked so good, I’m buying another 6 pac for the truck to add again. First 6 cleaned enough to stop the engine light BUT I doubt it cleaned them completely. Figure I should continue what’s working. Really really works for check engine light due to 2 separate O2 sensors faulting. Review: Worked more than 4 times! - Used this on several of my cars with the P0420 code. It worked almost every single time, just follow the directions and don't fill up your gas tank until you are close to empty. This wont fix mechanical problems; but it's probably the best chemical cleaner out there for cats that doesn't involve taking them off and washing them. EDIT: Where I live the smog requirements changed for classic vehicles. I was now forced to register my 1991 Hardbody truck with a smog check. I take very good care of it, but since the car has past the 200k mile point and nissian is known for making shitty catalytic converters; I gave this another shot. Truck passed with flying colors. Not sure what is in this stuff; but the people making it sure as hell know what they are doing. I'm also not sure how the 100% guarantee works. This can't fix mechanical problems; so if it doesn't work your vehicle has a mechanical problem. ## Features - ADVANCED FORMULA.

I have poor acceleration in my car, especially when going up hills. he said my catalytic converter is clogged. So try this before replacing my converters. He said to add two bottles to 12 or more gallons.. run it to 1/4 tank.. add another bottle bring to half a tank and run it till 1/8 a tank. He said highway to get it warmed up nicely **Q: Cómo es el método de uso?** A: No funciona. **Q: Do I use this on a full tank of gas? Or in a tank that's near empty?** A: I believe I used it with about half a tank of gas. Suburban has 40 gallon tank so..... I have had no cat. converter or O2 codes since running this through system. **Q: Do these cleaners work for the bad smell that cats put out sometimes?** A: All I know is that it is supposed to help your vehicle pass emission inspection. If you follow the directions it might not work. The ratio of 16 oz : 16 gal didn’t do any difference to my vehicle. I don’t recommend this product ## Customer Reviews ### ⭐⭐⭐⭐⭐ This actually works when their competitor didn’t *by W***R on March 21, 2021* Worked perfectly, 2010 F150 5.4 with 244,000 miles.

I had it looked at at the local garage, and they hooked up the analyzer and it said that the catalytic convertor seemed bad, and also the oxygen sensors. After running most of the cleaner through it, it seems to be running much better. I had never heard of a catalytic cleaner. Hope that takes care of it, as the Insight is the most economical running car that I have ever had. It has 220,000 + miles on it now, with 57+ mpg lifetime. I bought it with 104,000 miles on it with 56 mpg lifetime. So, it has been making over 58 mpg since I have owned it. I knew that a new catalytic convertor would be expensive, but found that the oxygen sensors were even more expensive. So, crossing my fingers that this takes care of it lol ## Frequently Bought Together - MotorKote Catalytic and Exhaust Treatment | 16 oz., Single - Motorkote MK-HL32-06 Heavy Duty Hyper Lubricant Engine Treatment, 32-Ounce, Single, Black - MotorKote MK-FO16-06 Fuel Optimizer, 16-Ounce, Single --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/80146168-catalytic-and-exhaust-treatment-16-oz-single](https://www.desertcart.com.ar/products/80146168-catalytic-and-exhaust-treatment-16-oz-single) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-26*
