Mid-grade gas - why does it exists, who uses it and how much of it is really sold? I've been driving for over 40 years now and have never filled up with mid-grade gasoline. I also, to the best I can recall, have never seen anyone filling up with mid-grade gasoline.
That all noted, do any of you regularly use mid-grade gasoline? Are station owners required to offer it as part of their agreement with the brands they represent? It is pretty much available at every service station but my understanding is that there really is no such thing as manufactured mid-grade gasoline and that it is just a blend of regular and premium gasolines performed by the pump itself.
