djr7572 Posted July 29, 2017 Share Posted July 29, 2017 Hello! New to the forum and new to Subaru. Just bought a 2017 Legacy 2.5i Sport. I've only been driving it for 4 days ... have 370 miles on it. The MPG guage and the "miles until empty" guage are behaving very erratic. Does it take some time for this data to settle down and become accurate? My MPG reading, on a 35-mile drive, was bouncing around all over the place, and never really settled in. Is this normal? Also, look at my gas guage needle - it's just one mark above half a tank, yet my "miles until empty" says I've got 390 miles to until empty. That doesn't sound right at all. Or does it? Maybe I'm not understanding how this data works, but my assumption is that the car is so new and this stuff takes a little while to dial in ... ? Any help or tips would be appreciated! Am I needlessly worrying about this? Link to comment Share on other sites More sharing options...
