I've been getting between 290 and 310 lately... my last tank (i just filled up a minute ago) was all in town driving and i got 305 with a 20 gallon fill, then my tank b4 that was mostly in town with a trip to Thousand Oaks, then Montecito, then Thousand Oaks back home to Ventura, which put me at 320 on a 20 gallon fill.....
it has made me happy considering i lost my job at honda and gas prices continue to rise...
