A tip for those who go over mountain passes often.
When going on long inclines to the summit on cruise control, the transmission is often in 5th, and the instant MPG dial showing 15mpg. Normal, right?
But, if you switch to manual and force into 6th gear, you will notice the mpg dial showing 17-19, without vehicle slowing down.
I have done it countless times. It might give you 1-2 overall MPG increase on a tank of fuel.
