Review: Promising ... - I don't want just to say it works without giving details, but it could be hard as there is no objective data or measurement to present. I will try to tell the long story short, and you can see how it is working. 2005 Honda Pilot, over 190k miles. Late 2019, the check engine light came on for the first time while I am driving and it went off before I could brought it to the shop to check. I mentioned it to the mechanic when brought my car to do maintenance, he checked it and said the it was catalytic converter and asked me to just pay attention, and probably no need to do any check or fix soon. The light came back on and then off maybe a handful of times, but remained off for the most. The car passed the emission inspection at the end of 2019 without any problem. 2020, due to Covid and work from home for over nine months out of the year, I did not drive the car much the entire year, probably about 300 miles a month(used to be 1.3k - 1.5k miles a month). The check engine light came on and off became worse and worse. I bought a code reader and checked it, it is P420. I kept on discussing with my mechanic he kept on saying it probably not worth the effort and money to diagnose and fix, and if it can pass the emission, it should be okay. By the end of the year, I was driving with the check engine light on around 80 to 90% of the time. The light did go off once a while but it would come back on shortly. The car passed the emission test again in December. While discussing about the check engine light with the gentleman who ran the emission test, he told me that there might be some cleaner I can use to see if it could correct the issue. That lead me to buy this. During the first bottle with about 16 gallon of gas, the check engine light went off after about 50 miles of driving, stayed off for about 80 miles, then came on again and stayed on for another 60 or 70 miles, then off and on again right around time the tank was near empty (240 miles). I got another tank of gas without the cleaner, about 30 miles later, the light went off, and now I have about 150 miles with this tank of gas it has stayed off. My conclusion is that it is very clear, this cleaner works. I plan to get a few more bottles and continue to use it until the check engine light stays off for good.
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

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.
