3.8 L
Highway driving = 28-29 mpg driving through Utah and Idaho (75+) with 4 passengers.
Mixed driving = 22-24 mpg.
I'm a happy camper.

Interesting. I've driven 5,000 miles in my R-Spec. My lowest mpg was 14.9 (50/50 city/highway) and my highest was 21 mpg (85% highway). My average is 17 mpg mostly highway.

And I don't have a heavy foot. Do you hypermile to get those numbers?

I'd say we kinda drive the same routes and style...

my local driving matches your 14.9-17mpg
however my highway driving is around 24-25mpg

^ note these numbers are from the car's faulty calculator. (so in reality subtract 1-2 MPG)
