I was so skeptical that this would even work, after a mechenic told me $2000+ to fix the cat converters on my 02 ford escape, I figured, it couldn't hurt to try, so I got 2 bottles did as it said and it really did clear the converter code, my truck passed inspection we'll see if the light comes back on or if anything else pops up, but for now I can say it worked

I bought this the to help with the P4032 Code error that I received after the lovely shade of "Check Engine" turned on. My mechanic suggested I use this to treat the cat converter. His instructions is to pour a full bottle in a half tank driving until you are on E and then pour it and refill it again. **[Please use instructions method in which suit you best, since my mechanic has work on my truck for years,that is what he suggested for me]** You can follow the instructions on the box as well. I did exactly what he said and the Check Engine light went off. Now this is not a cure for the P4032 error code that we get, this is a temporary fix to pass your emission, or until you save $ to buy the Cat Converter and mine for my Mitsubishi Endeavor [2008] is pretty expensive. I read lots of reviews and I can honestly say that this stuff does work. I do dont go into panic mode when I see the "Check Engine" I really hope this helps any one with a Mitsubishi Endeavor vehicle.

My "N.O." (oxides of nitrogen) level was very close to the limit two years ago when I had my Toyota pickup tested. I thought I might not pass this time so I ran a can of GTP through it with about 12 gallons of fuel. After my tank was down to 1/8 full, I filled the tank and went for a smog check. My vehicle passed. Two years, the NO level was 507 PPM. This time, the NO level was 421 PPM. I'm satisfied. I was thinking I'd need a new catalytic converter or an O2 sensor (but that was replaced 4 years ago). I didn't require any repairs to get it to pass and the oxides of nitrogen level was MUCH lower than two years ago.

I've been using this product for many years. On two occasions early on when one of my vehicles failed the smog test, I added this product to my full gas tank, ran the vehicle down to 1/4 tank then had it smogged again. This time it passed. The same thing with my daughter's old pickup. After adding this product and retesting it passed perfectly. Ever since I run 3/4 of a tank of gas with the CRC added through my vehicles before smog testing and I have never failed a smog test again. This stuff has worked great for me!

Sequence: Failed inspection (Atlanta, GA, 2004 Rav4, code=P0420), added to 3/4 tank of regular, all engine check lights went off within 1/2 mile (they've been lit since 2006), drove ~200 miles, filled with premium, went for reinspection, easily passed. Very impressed, as was the inspector. Year 2: Added to full tank, consumed that tank, filled up with regular, passed again. Just works.

Worked for me! I have a 2003 Honda Civic that has 171K miles on it and needs a new catalytic converter. I got 2 bottles. Added one at half a tank and topped it off with 1/2 tank of premium. Drove it about 100 miles, added another bottle and topped that off with premium. Drove another 50 miles. Had the check engine light reset, drove 10 mins at highway speed and had it inspected. Passed with flying colors.

If this stuff wasn't so highly flammable I would kiss it. I have a 2007 Honda Civic EX, 191000 miles. Check engine has been intermittent for the last year and a half, coming on for a few days, being off for a month or two. Code was for the catalytic converter. Passed smog once when the light was off. Of course, the second I decided to sell it, the light came on and stayed on. Quote for a new cat was $1800 (I'm in CA). It's only a $5k car so this was a bummer. I found this stuff online and thought it was worth a shot. Read the reviews and figured I had a 50/50 chance of it working. I poured it in a 3/4 full tank, drove all over (the first time I've been frustrated at the amazing gas mileage of a Civic) until empty, filled up with premium, drove home and parked it. Next morning woke up, turned the car on: viola. Light off! Passed smog! $1787 saved (I bought two bottles)!!! Best stuff ever as far as I'm concerned.

My car has 2 catalytic converters that need to be replaced. I live in NW Indiana and we have to get our cars emission tested every other year and unfortunately this is the year it had to be done. The check engine light was staying on and a vehicle will not pass with the light on. I used this product several days before trying to test emissions. The light came off almost immediately and it passed the test!! Now I have two years to decide what I want to do with the car.

Same story with the catalytic converter needing replacement. I poured the bottle into a full tank of premium gas, burned half the tank going up to Michigan for the weekend (long drive, high RPM), burned the other half on the way home. Halfway home the check engine light turned off. On Monday went and passed the emissions test. On Thursday the check engine light came back on. Sorry environment, too poor for a new catalytic. In my opinion this juice did exactly what I needed it to do.

my car failed E Check 4 times. I was at the end of my rope. I followed the directions. Added it to my gas,drove it to almost empty and filled the gas tank went back to E Check for the 5th time, The guy testing my car ,handed me the report and said you not only passed, you had lower emissions than Ive seen from newer cars in months. I was so doubtful of it passing I downloaded the form for a refund. Shame on me,this stuff really worked on my 1995 Saturn with 198,000 miles. Amazing stuff
