    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.

                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,

                      • Q:

                        All other fuel system cleaners say pour in product, "THEN" fill the tank with fuel. This makes more sense to me for mixture advantages. Why does CRC insist on doing this process backwards? I don't need to pass a test but keeping my 05 Grand Marquis running perfect is very important to me. There aren't many (grand paw) Marquis out there with 450h.p. averages 20.8 mpg and has made many enemies out of Stangs, Camaros, and hemi mopars. I need to know how to use this product to clean everything it claims it will. P.S. the guys at Advance Auto in Jackson, Tn. know me and my car.

                          A:

                          I'm happy to help, Poppy! Sounds like an awesome sleeper car! I can tell you take a lot of pride in your 2005 Mercury Grand Marquis and want to keep it running at its best. The CRC Guaranteed to Pass® Emissions Test Formula (Part No. 05063) can be helpful in situations where you need extensive cleaning quickly to help pass an emissions test. The active ingredient in this product is polyether amine. This along with petroleum distillate, sweetened middle petroleum distillate, solvent naphtha and naphthalene make up this product.

                          Polyether amine can be found in many additive products. This may also be in the gasoline you use in your vehicle. If you are using a top tier brand gasoline, it may contain this chemical. Typically, they'll have enough to keep the engine clean in the regular and mid-grade and enough to actively clean in the premium grade.

                          Since you are not trying to clean up the vehicle for an emissions test, a great option would be Chevron Techron Concentrate Fuel System Cleaner (Part No. 65740 [20oz] or 67740 [12oz]). If your fuel contains ethanol, you may find that an ethanol treatment, such as Sta-bil Ethanol Treatment (Part No. 22264), Lucas Oil Products Ethanol Fuel Conditioner (Part No. 10576) or Sta-Bil 360 Protection (Part No. 22284) can also help to keep your vehicle in top shape.

                          A:

                          I'm happy to help, Guido! CRC Guaranteed to Pass® Emissions Test Formula (Part No. 05063)has been shown to reduce CO, HC and NOx emissions and may help your 1990 BMW 325i pass its idle HC emissions. CRC offers a double money back guarantee if you are unable to pass your emissions test after following the product instructions.

                          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 chemical is also found in some of the Top Tier gasoline brands as well.

                          This chemical 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.

                          This item could help you pass the emissions test. However with out the presence of your vehicle we cannot provide you with a 100% answer.

                          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.
