No offense intended, I do have an engineering degree and have been wrenching since I was old enough to turn one. I am well aware of gear ratios and the effect on engine load and fuel economy.
My point is, with numerically higher rear gears the engine would be under a lighter load allowing more use of cylinder deactivation.

Yes but the electric motors have a lot of torque.
so it benefits with the 3.08 ratio...
6qt of 5-w30? or 0-w30?.. mine runs at 55-60PSI@1500 rpm on the highway 50PSI idle....
FYI my last fill up came in at 25MPG Combined (247miles)
19-MPG City
31-MPG Highway
25-MPG Combined
(US MPG)
40% city 60% highway
If you want your V4 mode to work better at higher speed I suggest using 91-93 OR E30-E85 (only if you got a FLEX Fuel..)
get it from a name brand like Chevron or Texaco I seem to have the best luck other gas stations seem to be pumping 87 at the 91 price ( I could tell since I was keep dropping to 3rd gear were it did not on 91octane)
in v4 you lose power because of the retarded timing because of engine AFM stuttering...
the AFM stutter with 87 octane fuel sucks I see more v8 mode and 3rd gear with 87 octane then with 91 octane fuel.
(highest here unless you get racing fuel but not worth it since it cost almost 10$ a gallon)
