Review: Great product with a great company standing behind their commitment. - I’ve had this product work before, and it’s been good. This time it did not, and I actually used the warranty/guarantee process and they stood by their assurance and refunded me! I would absolutely buy the product again, my car is a 1995 BMW with <75k miles and it failed CA smog, but using this made it pass before. After the failure this time I had the car checked and it needed an O2 sensor, which fixed it for good, hopefully. But I would absolutely recommend this product to others - if the car isn’t suffering from something major, it DOES work! And the company stands behind it.
Review: It works! - My 2005 Jetta failed the inspection and my mechanic said (after clearing the engine light) that I should drive the car for 20 min highway and 20 local. We've tried that the whole day but out of three lights on his device only 1 went away. Next day the light engine came back. After not being happy with the explanation offered by him (a family friend) that I should keep driving it until we get lucky I went online and found CRC 05063. Followed the instruction (one bottle on full tank of gas). Before my tank was under 3/4, engine light went off!! At half tank I went and did the inspection - IT PASSED! I am really impressed! Update August 2015! I have been using this product for 2-3 years now and if it is not working for you please read. In July I have used the first bottle and took my 2005 Jetta for inspection. It failed. Ordered a second bottle and it failed again. My mechanic said keep driving. Did 200 miles in one day and nothing. Decided to take matters in my own hands and ordered Autel MaxiScan MS300 ($18, it allows you to read and delete codes). There were two faults - EVAP and 2nd something about Oxygen. Went online and this is the first time I heard about driving cycles. These are steps that you have to follow so that your car's computer can start measuring all the parameters needed for the test. Driving cycles are not exact science but I tried to follow the instructions as much as I could and after just 20 minutes (10min city and 10min highway) ALL the parameters were set and I passed the emission test with flying colors! So, just before you give a comment about CRC like "tried and didn't work" be aware that there are other things you have to take into account.

## Questions & Answers

**Q: How do I get my money back it did not work**
A: I once submitted all the required paperwork for the money back and they never sent me a dime.  I did see slight lowering of some numbers but very little.  Basically buy it but don’t expect to actually get a refund much less twice the amount

**Q: Does this clean oxygen sensors and catalytic converter?**
A: This product cleans out just about everything totally from the gas tank to the exhaust tailpipe. Severely clogged systems may require a second treatment but anyone that lets it get to that point is probably going to need a lot more than an oil change and a few spark plugs.

**Q: Does it have to be done right before the test or a week before is okay?**
A: i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter;  if you're not passing due to HC, that is a tune up and maybe new O2 sensor...

**Q: Will this help with the egg smell I get once in a while after I floor it. Doesn't stink all the time only once in a while**
A: Yes, it will.  The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips.  This product cleans all of these areas.

### ⭐ Miracles don't come in bottles.
*by J***O on August 2, 2025*

I drive a 2010 Honda Pilot and the Check Emissions light came on. I tried every additive I could find to try to clean out the catalytic converters, but alas there was no escaping the costly replacement. I drove the vehicle with the warning for over a year, and while I didn't feel like I was noting any drag or performance issues, once I had the converters replaced, I noticed the improved engine response. I know the sensor was working correctly because in the extreme cold, the error would clear, but as soon as the temps warmed up the check engine light would reappear. It was better to bite the bullet and have the issue corrected, I found. Despite all of the videos on YouTube assuring me I could simply blow my issues out, I was never able to do so.
