Its a lil low but in the realm of possibilities if you only drive in town and are VERY heavy footed......I'd probably look at the Cats too, although maybe there's a SBC brake failure going on? Worth questioning.
For reference, my 09 (OM642) gets ~25mpg in town lugging around at 1100-1200 rpm. Highway at 80mph it gets 38mpg; guessing at 65mph it would get in the low 40's. It does get up and roar whenever you put your foot down hard and challenge the traction control as another poster mentioned.
The Bio use concerns me, may be inj or pump issues still unresolved. I believe B5 is the max bio limit.
