I suppose that with my current cold and snowy winter weather, my 91 octane fuel will likely deteriorate in its actual octane level over the winter since I'll be lucky to put on 50 miles per month, given the cold temps, the ice and snow, and the Nitto 555R2 drag radial rear tires?
Also, is it safe to add Stabil (fuel stabilizer) to it when running a supercharger?
(Never had to ask these kinds of questions before!)
