Can anyone tell me if the gas in south jersey is still formulated differently from the gas in northern NJ during the winter months vs summer months? I'm from Stanhope and got my last tankful down in Lakewood (a Zaino run, believe it or not!) and I swear I'm getting better milage: 276 miles @ one half tank !!! It's a newbie 05 with 2k miles. Or am I wishful thinking?

I ain't aware of any difference in the state, only thing I can think of would be different grade from different companies,
