So this whole RAFE, or Running Average Fuel Economy, is new to me. I went and checked mine then did some googling to better understand what it is. The concept is still clear as mud.

My trip B which has not been reset since before I bought my truck is at 16.2 now. My RAFE is at 16.8. Apparently this is a last 500 miles average used to calculate distance to empty.

"Distance to empty is calculated using a running average fuel economy,
which is based on your recent driving history of 500 miles (800 km).
This value is not the same as the average fuel economy display. The
running average fuel economy is re-initialized to a factory default value if
the battery is disconnected."

I wonder what the factory defaults are.

So, not to start a pissing contest between the motors, what is your RAFE and if you know, what are the factory defaults?

@ 4300 miles with only a trip to central Texas before break-in. I couldn't get to 15 on that trip.

By the way, this is a 6.2.

This is mine. 2011, 5.0, 3.55 gears. My instant mpg gauge is showing 17.5 average right now.

I feel like I'm getting screwed over. I have a 3.7 4x4 supercab with 3.73 gears and mine is 15.2 mpg. But my driving is %90 city with lots of steep hills.
