Re: 2014 GC gas mileage 3.6L
One last update to the mileage I get from my 2012, 5.7 liter Laredo 4x4.
I drive mostly in cruise at 68 to 70 mph on the fwy, so my numbers are probably high.
I just got back from a trip to Tahoe and back, about 550 miles round trip.
So, fwy to and from Tahoe and 3 days driving around the north lake and then some driving around both Walnut Creek and San Ramon on the way home. That's with 2 in the car, 2 sets of golf clubs and luggage, and 2 bikes on a hitch rack in back.
I averaged 20.9 mpg for the entire trip and if it was just the fwy portions, it would have probably been 22 mpg or so.
So while I get down to ~15 mpg when I just drive around town; I am happy with the freeway mileage.
So perhaps my results can help people decide on either the 6 or the 5.7L.
