Yeah kinda hoping it would be to the lesser side, thats what I was thinking too. My fuel gauge has been hitting "E" at around 240 but per the fill up last night it showed I still had roughly 3 gallons left in the tank because it only took 12.5 ga. to fill so factoring in the tire dia. its actually doing better than it appears to be, I calculated about 19 mpg city at the current setup:-Dgotta love it.
