Same State and City and it depends on what side of the city you are on. Even on post there is no difference. Sad to say is it is actually cheaper off post. I only use 89, used 91 couple times didn't see any gains.
Yea I used 91 once,got the same as with 89.I get 1 MPG less with 87.If you do the math,you break even,by paying less.From what I heard about the Hemi,its PCM is set up for 89,91 would be a waste.................Kevin.
