## Description

PERFORMACE! SAVING!DURA LUBE SEVERE CATALYTIC and EXHAUST TREATMENTDura Lube Severe Catalytic and Exhaust Treatment is formulated to protect and treat the Catalytic Converter and Exhaust System from oil poisons. This will aid in reducing the carbon footprint of your vehicle and improving overall performance; helping to increase fuel efficiency, and protect your converter. Use before replacing your catalytic converter. Directions: Add full bottle into 60 liters 16 gallons of fuel or 30 mL per 3.8 L 1-Ounce per Gallon. Last up to 3 months or 5,000 miles - whichever comes first.Manufacturer Note:PLEASE NOTE THAT THIS PRODUCT IS NOT INTENDED TO BYPASS, DEFEAT, or SHUT DOWN EMISSION CONTROL DEVICES INCLUDING OXYGEN SENSOR ELIMINATORS, SIMULATORS, OR OTHERWISE ACT IN ANY WAY AS A TUNER OR DELETE KIT. THE USE OF THIS ADDITIVE WILL NOT ALTER THE FUNCTIONALITY OR OVERIDE MALFUNCTION INDICATOR LIGHTS ON AN ENGINES OBD SYSTEM.

Review: This thing works!! - I have used it twice on my 25 year old car and it helped my car pass my state's emissions tests. Before the treatment, my car had a blast of white smoke coming out of the muffler and once I started using it the smoke was virtually gone.
Review: It got the car to pass inspection! - This was added to a car that's around 12 years old that had the check engine light come on periodically. It was taken in to get an inspection and failed due to a fail on the catalytic converter. The estimate for the repair was about $2500 because the catalytic converter is attached to the exhaust manifold and the labor to get it all taken apart and put back together is substantial. The car wasn't really worth the repair given the mileage on it, but we weren't ready to buy a new car just yet. We decided to roll try this out to see if we could pass emissions one last time and have more time to shop for a new car. It was easy enough to use... add it to the gas at the next fill up and drive. It took a few days to get a little past the halfway mark before the check engine light went out. We took it in, it passed inspection, and we got the sticker. The light came back on a couple of days later, but turns off for about 30-60 miles every so often. We didn't notice any other benefits... performance and mileage were about the same as before. This may work as a preventative for some people, but we were long past that point. This isn't going to fix a car's catalytic coverter, but it'll buy you some time before you get a repair or get a new car and sometimes that's all you need!

## Questions & Answers

**Q: What's good for diesel engine 6.7**
A: Dura Lube also makes a Diesel version which works best for Diesel Catalytic and Exhaust systems.

**Q: Can I combine with Garantee to pass**
A: It all depends. Are you trying to pass an emissions test? It may take several times with several different bottles to clean out. Also it depends on how bad your catalytic is. This is not a miracle worker if you have a bad cat. It does a very good job on cats that are not completely packed. Your question is too vague

**Q: I have two vehicles, one with 80k miles and one with 110k miles. They both run fine with no check engine lights. Is this a safe preventative cleaning?**
A: Yes, that would be a good idea I do the same for mine . It’s a cheap piece of mind .

**Q: Donde se vierte el liquido**
A: En el tanque de gasolina

### ⭐⭐⭐⭐ Product worked temporarily
*by J***N on October 17, 2023*

I give few product reviews because most of the time they don't work. So, when I purchase I pray! Well, I did not pray this time but the product worked. Wow! Therefore, I can say with all honesty...this product cleared my check engine light. Here is what I did: First, do not clear the check engine light with a scanner. If the light is showing in your dash, then OK (leave it). Next, make sure you only have around a quarter tank of gas. Now, set your Trip A meter to zero (or calculate 25 miles by adding it to your current odometer reading). Next, place the entire bottle of the product into your gas tank. Start the engine and drive around 25 miles (mine worked at 21 miles). Note: you don't have to drive right away. You can drive the 25 miles or a period of time (mine was two days). After driving for 25 miles you should see the check engine light go out. Good luck! Update (1): check engine light came back. update (2): Found the problem. The gasket near the oxygen sensor (bank 1 down stream) had a leak. Gasket replaced and check engine light went out. So, check for exhaust leaks before making a purchase.
