P.S.~about the link and me thinking theres something funny going on:::
I specifically noticed a 5% DECREASE in MPG from September 22nd to October 23rd
Interestingly, I paid out an average of $2.609 in that time period. The highest average prices I've encountered.
Anyone have any thoughts or similar experiances?
