tHE ONE THING i HAVE DONE ON BOTH CARS, the Q45 & Sportage was to get a baseline of real driving. I would find a 10-15 mile flat stretch of freeway and run up and down at 50, 55, 60, 65 &70.
(I use a scangauge)
I would record the rpms and the mpgs for each.
Then I could determine at what rpm I got the best mpg.

I find it hard to believe that your best mpg is at 2800 rpm
The Q45 was at around 1750rpm
THe Sportage is aroung the same....but that would have me driving 45mph!

THe name of the game is reducing rpms at cruise.
