I live in Cali and just had my smog check done. I have been using TCW-3 Blue Velvet, in my gas for about a year now. Incredible results. Most Cali cars fail because of high NOX. 2 years ago my NOX reading was 237. That's about mid-range, I think. This inspection, my NOX registered a 2. Wow, what a difference.

Ya i can account for the same success. Im in cali also. Ive been using pennzoil tcw-3 for almost 3 years now. Before the tcw3 i was getting mid range results like you. After using it for awhile some of the readings were actually 0! i coudnt believe it. Now is that because of the tcw3 im not sure but thats the only thing i did differently between my smog checks. Its good stuff i know that much!

Yeah, it's nice to get that out of the way for a couple years. I know I felt like that when I had my 4th generation with an aftermarket y-pipe.
