Review: It lasts a long time, , cleaning. - Excellent product, I liked it, it works, I recommend it.
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

*by J***G on October 28, 2025*

Ran 1 bottle added to 1/2 tank gas in Subaru Outback with 214K miles, vastly improved performance followed by 2nd bottle added to 1/2 tank and it did not seem to improve past just 1 bottle. Did not make ODB2 lights go off. fast delivery, good value, and I will buy again.
