67 dart emissions

I dumped a gallon or so of alcohol (believe it was grain but...) into a few gallons of gas on my one truck, some old geezer suggested it. Leaned it out enough to pass. Was told by one of the employees at the sniffer station that there equipment will pick certain additives up. I thought that the law had finally been settled about the collectors insurance? Last I looked it was on the States web site....Did some digging around, looks like if you have collectors insurance you are exempt?
