I hope you weren't saying all that "first of all/second of all" stuff to me by quoting me
Sure it's a performance vehicle, but the manual still says to just put regular pump gas in it. My experience is that "performance vehicles" are more likely to experience lagging or hesitation when putting cheap gas under stress. ..cruising in traffic gas is gas, but when you put your foot in it, you need something that might not have water leeched into it from a crappy storage tank, poorly filtering pumps, etc etc etc, that's why I even made my post.
And please don't lecture people on what they can or should afford. Again, when you're cruising, gas is gas.
