This month's SportsCar (SCCA rag) has an ad for CRC Guaranteed to Pass emissions Test Formula additive. Instructions are 1, Add to full gas tank. 2. Drive until empty, refuel. 3. Pass test.
Pass your emissions test or double your money back.

99% Isoprophyl alcohol will work, NOT rubbing alcohol.

that stuff dosesnt work. and to get the moneyback you have to take it to a mechanic to get it fixed and provide a receipt for it. its just not worth it. try whats on this thread first.

I am in the process of getting my emissions done for a blacktop 180sx SR20DET, and was wondering if the ethanol/crc formula is only effective for the NOx rating? I actually went ahead and tried the CRC guaranteed to pass formula, I passed everything except my CO% at both 15mph (failed horribly) and 25mph.

I am now debating using the ethanol technique, but I am hearing I might need to change my o2 sensor, since its my CO% that is failing. Any kind of feedback helps, thanks!
