I dont agree with the part about running in 4cyl mode. One trip to Utah i got 19 and was running speed limit which is 75 here and 80 across Utah and it was only in 4cyl mode going downhill.

To do 75 to 80 no cylinder deactivation system will be able to shut off cylinders, just to much HP required to stay at that speed.

Except like noted above "going downhill"!
