I went from SF to Monterey Park, about 420 miles on a full tank with 5 passengers and a full trunk. Filled up before the light came on. I am guessing I have another gallon or so before the light, think I could have gotten 450-460 miles on a full tank. Averaged around 21 mpg, zooming on I5 at about 80-85. Have fun cruising up this way.
