Let's start over......
Interesting....wonder what the '15 has.
But I noticed the same on mine, but had no idea when it changed, since I don't buy a new truck every other year like you do
I wonder at what speed do they use for the mileage ratings on the hwy and if they have the AC on or not? I'm getting right at 19.5 on a hwy run at 65 to 70 mph or whatever the posted limits are...and that's running the AC.
Mythbusters busted the AC being on lowers MPG
I'd have to question mythbusters on this...years ago a 1 to 2 mpg drop in gas mileage was common when running the AC. Now it's more like 1/4 to 1/2 mpg but still a drop. Hard not to run the AC in Louisiana with temps still in the high 80's and humid.
