At 10,000 miles with only using premium fuel, 275/65r20 BFG KO2’s, and a 1 inch motofab level, I’m getting 18.2 mpg lifetime. Very happy with my truck.
Here’s my 2020 Satin Steel AT4 with the 6.2L. I absolutely love this truck so far. I told my wife that these AT4s are the best looking trucks I’ve ever seen.
I've got 29,400 miles on my 2015 CC Z71 5.3, 3.42.
I had an oil leak issue from 10,000-18,000 miles, but since that was figured out, I've had no issues. I really enjoy driving this truck.
I've got a lifetime mpg of 18.2 (according to the AFM)
