First time for me too but in 12 fill ups. Last tank was 40.4 by hand. Only thing different is the weather is getting a bit warmer (hence not using the heater as much). Oil change to 0W20 1600 miles ago may be starting to help too.

CoolShock was less than 1 off.

I've lost faith in the TANK AVG reading on the MFD. When comparing it to hand calculations after a fill up it has varied by as little as 0.2 MPG and by as much as 4.3 MPG for me.
