MPG is one of the indicator's of a well tuned Morgan or one that is not so well tuned. I keep track of MPG. Mind You in the U.S. 4 32oz qts = 1 gallon. Imperial Gallons confuse Me a bit. My Bitsa averages about 20 U.S. MPG on a trip. As I rarely drive in the City in My Morgan I really do not know. The 2.0 Zetec(w. Weber DCOE) DHC is about 24MPG and the TR powered +4-4Str 22 MPG.
