Most US states require mandatory emissions standards testing for passenger vehicles. Deposit buildup in the fuel system can cause increased emissions, reduced performance and contribute to poor fuel economy. CRC GUARANTEED TO PASS contains powerful detergent additives strong enough to remove harmful carbon and varnish deposits from the fuel system and emission control components in gas-powered vehicles. CRC GUARANTEED TO PASS reduces CO, HC and Nitrogen Oxide emissions and is effective for both tailpipe exhaust analysis and more stringent OBD II plug-in, on-board diagnostics emissions testing methods.
This stuff works. I live in NJ where we have very stringent emissions testing and I have used this product 3 times in the last six years. Same car now with 140,480 miles on the clock and readings were about 40% of what is allowed, follow instruction on the box and you got it.

"This product saved me several times already."
Excellent product, I got "Check Engine" light, and my mechanic suggested I replace catalytic converter (about $1,000 job) before I go for inspection. A friend of mine recommended I buy "CRC Guaranteed to Pass" formula. I bought it, followed instructions, and passed NJ State Inspection with high score. I have more than 180K miles on my car, and this product saved me several times already. I would strongly recommend this product to my friends.

"I recommend this product a least once a year."
I was told that I had an EGR circuit problem that kept me from passing DMV inspection. A bottle of this product and 150 miles later, the check engine light went off and all was well and passed inspection. That was two yrs. ago and all is still well in the circuit. I recommend this product a least once a year.

"100% you will pass."
100% you will pass - 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.

"I didn't just pass the test I smoked it!"
Failed 5 times in one day and then pasted after one tank full, man this stuff works. My old 83 Dodge truck has been a pain! Even my main man hates my truck but he always come through with a passed AZ air tag. Just read the box and follow the directions. I didn't just pass the test I smoked it! CO2 was like zip!

"...passed GA emissions with flying colors."
This product works great. My 2003 Honda Accord 4 cylinder had 4 failure codes on GA emissions. Honda dealer wanted $2000.00 to repair the emissions, Midas $1200.00 and internet parts costs around $400.00. I followed the instructions and bingo the car passed at Auto Zone where it had failed on the first attempt and then passed GA emissions with flying colors. Total Cost $20.00 two bottles of
CRC and include 93 octane fuel.

"It's one of the few additives that is actually worth the money."
It does work. I've been using it for the last 5 years and have not failed a smog test yet. Both of my vehicles are over 23 years old. If you follow the directions and make sure your car is warmed up well before the smog test by driving it for 20 or 30 minutes on the highway, you shouldn't have any trouble passing the test. It's one of the few additives that is actually worth the money.

"It works exactly as advertised."
This is a very good product. It works exactly as advertised. In fact, we did not take our car in right away, so we wondered if we needed to buy another bottle, but we didn`t need to. It worked.

WHY SOUND VEHICLES FAIL
PREVENT COSTLY RETESTINGGUARANTEED
When there are no mechanical issues with their vehicle, many car owners still find themselves wondering why they have failed their emissions test. As a matter of fact, a mechanical issue is not the only reason for a failed test. A major cause is a dirty fuel system that releases harmful pollutants into the air. Deposit buildup can lead to increased emissions as well as reduced performance and poor fuel economy. CRC GUARANTEED TO PASS won't compensate for any repairs needed on a vehicle, but it will remove any underlying risk of a dirty fuel system producing excess emissions. Plan ahead and avoid the hassle and wasted money on a retest. Use CRC GUARANTEED TO PASS before your emissions test to ensure a passing result the first time - GUARANTEED.
