2020 M340i RWD w/ ~3,000 miles. Always Shell 93.

I commute ~60 miles/day. 54 of those miles are rural, low-traffic 65-75mph highway. 6 miles are light-traffic city driving. 31.4 mpg tank average as of this morning. Seems legit, as I'm regularly seeing 450-475+ miles/tank with ~14 gallon fill-ups. Very happy with that.

So on the high-end, 33-34mpg on laid-back EcoPro highway cruising at 65-75mph. On the low end, high-teens maybe touching 20 when romping around in Sport/Sport+. I don't really pay attention to MPG when in Sport mode .
