Mike, Tango (2005 M620) is doing approx 110 before light comes on, then only 22 max till empty.
Tank IS plastic tho, so different pump placing too

Ps: check out too on the UKMOC board, as is a bi-monthly discussion....................
edited to add: My M1000sie, same engine as your last MS, only manages 120 tops to the tank, & about 15miles from when the light comes on. On occasions, the mileage has been just under 100 miles till the tank is empty!!
