Well that may be but it does not explain why from 2006-late 2012 I averaged 17.5mpg on my daily drive and now I am only averaging 13mpg. I use QT mid grade and have since 2009 because I drive past one every day on my way to work. I did try premium about 2 months ago for several tanks and made absolutely no difference.
