GaS prices around here have dropped about 33 cente per gallon since hurricane Ike.
I have to use premium in my car so I don't even look at regular. Premium was as high as 3.97 just after Ike, and now it's down to around 3.64 per gallon.
My area Baltimore - Washington, Shell $3.42 for RUL and $4.13 for diesel. Its dipped to $2.95 RUL in the past month for a week then went up to $3.25 to $3.42.
Two local off brand stations Petro sell 15 cents per gallon cheaper for all grades and diesel.
Last time I filled up a guy next to me had a Dodge Ram Cummins total cost was $156 for a fill up 38 gals. I asked the guy how often he fills up and he said minimum of once a week.
