Unleaded Plus vs. Unleaded Premium
is there really a difference if i use unleaded plus gas instead of the suggested unleaded premium? my sister does it in her car (which isnt a porsche but also is suggested to run on premium) and has no noticeable difference in hp or gas mileage - is it ok for porsche engines to run on this type of gas for the sake of saving a couple bucks every time i fill up?
