2018 5.0 Highway MPG

[Dusten]

My computer reads 24gpm avg now, hand Calc to 22-23mpg. And that's mostly highway with lots of rolling hills here in PacNW. I bet driving through Nebraska would yield upper 20's

When I drove across country i was able to crest 25 and i've seen as high as 27(hand calculated and tracked via fuelly)

Just picked up a 2016 GT PP1 Manual..Live in MI so its tucked away until the snow goes away..planning on running MI to CA this summer. Want to budget fuel burn..what was your average HWY speed to get 25-27mph? Thanks..

Under 75. Anytime I went over 75 it plummeted.

Looking at my logs in states with higher speed limits I averaged 23.6 and states with speed limits closer to 70 I averaged 25.4
My trip that was 27 was like 60mph average
