Is NJ gas better than Massachusetts gas?

New Jersey gasoline is more efficient than Massachusetts gasoline? I seem to get much better gas mileage with both my cars when they are filled up in NJ. What gives?

We live in Boston, have family in NJ, so we make the pilgrimage at least two times, sometimes three times a year. Our older car (a 2002 Mazda Tribute V-6) goes one way on almost exactly one tank of gas so I fill up usually as quick as I can when getting to one side or the other. I consistently, barring traffic (Grrrr!Thanksgiving) get 22mpg going to NJ and 24mpg going back. Over the last 10 years I chalked it up to loss of elevation and perhaps tailwind and maybe less traffic coming East. Now we have a newer car with a bigger tank and better mpg. Not only is the difference more exaggerated, but I can arrive back in MA with nearly a half tank of NJ gas which I did this week, but that's not the mystery. Also, our new car has an mpg computer and not only did I notice a big change in mpg coming home (about 4 mpg), now I'm still using the NJ gas and I'm seeing 2-4mpg better gas mileage on my short 9 mile commute to work. Being an engineer, I know exactly what my mpg is with and without Air Conditioning and it's vastly better with the NJ gas. I just know I'm going to fill up this weekend with MA gas and it's going to drop back down. More ethanol? Some other additive? We use only name brand gas (Shell, Sunoco, Gulf, etc.) from various stations. One more side-note: Even though our MA gas mpg seems lower, I found one gas station here in MA where the price is good and the mpg is even 2mpg lower still? Is there a way to dilute gasoline and sell it for a lower price? Interestingly this same lower mpg supposedly name brand station gives a discount for cash instead of a higher price for credit. Thanks in advance.
