MANY, MANY THANKS FOR ALL THE GREAT INFO!!
I tried driving for a week with Overdrive and a week in plain drive.
Full tank gas for each series of trips and kept speed at 55 M.P.H. highway
and was some city driving each trip as well, probably 75 miles highway and
20 city miles each trip.
In drive 260 miles 11.22 gal {Can.} or 23.172 M.P.G.
[Can]
In drive 260 miles 13.47gal {U.S.} or 19.302
M.P.G. [U.S.]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In O.D. 319 miles 13.2 gal {Can} or 24.16
M.P.G. [Can]
In O.D. 319 miles 15.8 gal {U.S.} or 20.126
