Thought I'd quickly share an update re: my 2014 Mz5 Sport with A/T. Have been able to track consumption on last 5K+ miles/6+ months (Dec-June). The vehicle needed 212 gallons of regular 87 octane gasoline to go 5407 miles for an average of 25.5 mpg. (Mostly used Shell, BP, Marathon and Sam's Club fuel.) That was a mix of many short trips, decent amount of highway driving, tons of windy days, etc. Nothing really long though -- no trips out of state. I think the longest non-stop run was 130-140 miles.
While I had several fuel ups in high 20's and even at 32 mpg once, I notice that at some stations the "click" happens earlier than at others. So I almost ignore MPG in the short term. Also ignore fuel gauge. Not very precise. One time I needed 7 gallons to get to full even though I was just four "squares" short. Another time I was at half tank according to gauge but only needed a little over 8 gallons. I think other vehicles I've owned have been more accurate in that regard but it's not a big deal.
Interesting but expected data points... Dec-Apr MPG was at 25.0 but went up to 26.2 Apr-Jun. Slightly more highway driving and much warmer weather had to have helped.
