I put about 600/week on my Acura RSX DD and I've driven it for so long I know the light will come on about at about 370 miles. I've driven close to 400 miles but normally I fill up at around 350 miles. I figure also that if you're carrying around extra gas all the time (ie filling up at 1/2 tank every time) then that adds extra weight which might shave a mile or two off your average MPG? Who knows? I get roughly 31.5 MPG.
