Ok. Let's set the level of expectations here. This product will NOT magically fix oil leaks or reformulate the chemistry of your engine with magic snake oil. It is just an engine component cleaner,... but it seems to be a very good one.

My 1997 Camaro has just a hair under 240,000 miles on it. I keep it very well maintained and have never had to do any substantial engine work. A few months ago, my check engine light came one. I used my code reader to pull up a catalytic converter code usually indicating that the Cat, my O2 sensors, or all of the above are ready for the scrap heap. My wallet and I didn't like that option.

Before I go any further, let's take a second to explain what a catalytic converter actually does. A catalytic converter is a catalyst bed that initiates a chemical reaction that converts unburned hydrocarbons in your exhaust system into COx and water without actually participating the in reaction itself. (This is why it is called a catalytic converter). Unfortunately, the heat of the reaction also causes N2 molecules in the air to oxidize and produce NOx. So, a properly functioning catalytic converter must be appropriately sized to heat itself to the right temperature to "light off" the right amount of unburned hydrocarbons without getting too hot. Proper heating actually makes the converter "self cleaning, " burning off normal build-up as it runs.

So, a properly maintained catalytic converter SHOULD run forever. However, real life has a way of getting in the way. Engine parts foul, crack, leak, and get carbon build-up. This allows unburned gas, engine oil, or even coolant to enter the exhaust system and deposit loads of crud into/onto the emissions hardware, such as the O2 sensors and the tiny air passages within the cat.

Verified Purchase
I normally do not write reviews but, thanks to all of the other reviews on this product, I have saved a ton of money. The check engine light was on for our 2005 Honda Pilot. The dealership informed us that it was the catalytic converter and we would eventually have to put a new one in to pass the smog test--the cost? $900.00!! I started doing some research on products that would clean emissions and found this product on Amazon. Many people offered helpful advice in their reviews and we used some of those tips. Thanks to their time and effort to write a review, we saved the cost of a new coverter. This is what we did: we purchased 2 bottles of CRC. We filled the tank up with a quality premium gas and ran a bottle through. With about a quarter of a tank left the check engine light went off--great sign but we were still concerned about the test. We ran another bottle through with premium gas just to make sure it was clean. We then ran the car for about 30 minutes on the freeway and took it for the test. It passed with flying colors and the technician remarked that our emissions numbers were very good and the car was clean. I will be purchasing more of this product for our other cars. Thank you CRC and other reviewers for saving us money and time.

My 1989 Toyota SR5 V6 truck was a certified CA GROSS POLLUTER...until I used CRC Guaranteed to Pass formula. To pass smog, you MUST:

-Get an oil change(eliminates dirty, unburned oil fumes out the tailpipe)
-Tune up(new plugs, wires, cap/rotor)
-Run Super Unleaded 91 octane fuel(burns cleaner)
-Get catalytic converter very HOT(run at freeway speeds)
-Wash engine(runs cooler)
-Top off all fluids(especially coolant)

The CRC formula was my trucks' very LAST HOPE. If it failed again...I was going to sell it to the wreckers. After all, the truck had a full life at 227,000 miles. I did everything the directions asked and ran CRC through my entire fuel tank. On the day of the test - I drove the truck at 80+ mph on the freeway for a full 30 minutes before the test. Below are the FINAL RESULTS:

Hydrocarbons(HC/PPM)
15mph @1628RPM MAX=127 MEASURED=26
25mph @1562RPM MAX=108 MEASURED=16

Carbon Dioxide(C02/PPM%)
15mph @1628RPM MAX=0.55 MEASURED=0.03
25mph @1562RPM MAX=0.69 MEASURED=0.03

Oxides of Nitrogen(NoX/PPM)
15mph @1628RPM MAX=1031 MEASURED=115
25mph @1562RPM MAX=891 MEASURED=115

What do the above numbers say? It means the additive product literally SAVED MY TRUCK!!! Not only did it get low, like new car numbers...the entire fuel system and spark plugs are squeaky-clean again. Doing ALL the above is the ONLY reason why I got such crazy LOW emission figures! Verdict? Maintain your vehicle and it too, can pass the World's STRICTEST emissions standards(California).

If CRC ever wanted me to do a TV commercial for their wonderful product...I would GLADLY DO IT FOR FREE!!!

It's THAT GOOD...

I spent so much money trying to repair my car, but unfortunately nothing worked....My check engine light continuously stayed on....so my dad told me about this product, and I jumped on it as soon as i found out about it. I followed the directions put the formula in a full tank of gas, and 2 days later my check engine light went off....I drove the car till I had about 1/4 gas left and filled up again and passed the test....this is the real deal Holyfield!!!!
