OK, can anybody confirm this theory? Before the state inspection I put a bottle Guaranteed-to-Pass (G2P) to a full tank then drove 240 miles, the fuel gauge was at about 1/4 mark. I filled up then went to inspection, that means some of the G2P was still in the tank. Some people think that could mess up the emission. Any comments?

Should I drive until the tank is empty without doing anything then re-take the emission test? but if the theory does not hold and I fail the test again, what is the fine for expired state inspection ticker?
