Just returned from AZ emissions station this a.m. with the subject car. I filled the tank prior to this with one quart OS 130 and the rest with 91 Octane gasoline. According to the Kemco chart my 18 gallon tank with 1 qt of OS130 shld net a 5 point octane rating gain or 96 octane. Car ran beautifully and strongly and I passed the emissions test loaded and at idle for HC and CO. Will monitor plugs and performance as the ambient temps increase. I don't put many miles on this car.

Thanks for your inputs.
