    This stuff actually works! My check engine light came on due to an emissions problem...I bought a bottle of this, filled my gas tank up, poured the bottle in, let it sit overnight, took my car for a spin in the morning and it went off after driving about 5 miles!

    I used this in a 2000 Honda Civic VP.

    I used the product as directed but it did not work. The Check Engine Light came on four hours after I turned it off. I then bought a more expensive competing product to clean the catalytic converter which worked -- the Check Engine light remained off and the car passed the emissions test.

              Used on 92 Saturn sc2 and it passed with flying colors. It failed the first time and was throwing a code for egr valve. After using crc product the check engine light went off and it passed.

              Comments about CRC Guaranteed to Pass® Emissions Test Formula:

              It just plain works. Used it on an LT1 powered vehicle with 160k miles after it failed emissions. Followed directions and car passed with flying colors! Picked up some mpg too.

              Have recommended it to friends and it worked for them too.

              Only downside is you MUST add to full tank of gas and run it all out. When all you want is to get your plates, it is expensive and a bit aggravating to just drive around trying to run the tank dry. Worth it though to avoid a trip to the garage and likely expensive repairs.

                    well, to be honest the CRC did not work to pass the car, I had a clogged converter and the egr was not working right, but it did clean out all the gunk in the fuel system, the car runns awsome after you use it, if your car won't pass after you use it, have a teck look at your egr valve and catalytic converter, my car is old and if these parts are bad your car won't pass, your catalytic converter will get black powder coating on it in side. and there is nothing that will clean that off, but yes crc did bring the numbers of the test down by half, so it dose work, just not on a car with warn out parts,

                          I have a 1995 Jeep Grand Cherokee Laredo 6V with 185K miles and I'm in California. My first smog passed all with exception of NOX at 15 mph. Allowed max. is 457 and my car came in at 500. At 25 mph max. allowed was 533 and it came in at 314. Will this product help and possibly make it pass a second time around? Thanks!

                            I'm happy to help, MP! It's definitely possible that this CRC Guaranteed to Pass® Emissions Test Formula (Part No. 05063) may help you pass your emissions test in California with your 1995 Jeep Grand Cherokee Laredo L6. This product utilizes a chemical called polyether amine or PEA which is also in other fuel system cleaners such as Chevron Techron Concentrate Fuel System Cleaner (20oz. - Part No. 65740, 12oz. Part No. 67740), Gumout Multi-System Tune-Up (Part No. 510011) as well as Gumout Regane products and others. This additive is also found in some of the Top Tier gasoline brands as well.

                            This additive does an excellent job at cleaning engines and reducing emissions. CRC recommends that you run this product through a full tank of fuel before going for your emissions testing. It is also recommended to make sure your vehicle is up to operating temperature before going for the testing as the engine will not be at peak efficiency when it is cold.

                            I doubt it. If your Nox level is that high, it usually means one of two things. Either your engine is running hot or you have a lean air/fuel mixture.

                          my 1996 chevy tahoe was running very badly so i replaced the distributor cap and that solved one problem but created another. now my check engine light is on and it sent a code 430 which is saying my converter is bad and needs replacing, $1000 repair. i can't pass emissions so i was wondering if this product will solve the problem and let me pass my test.

                            I highly doubt that this will help you pass emissions. Your problem may be as simple as a bad O2 sensor behind the supposed bad catalytic converter.
