I have a 2006 Auto w/ 4.10's and 20k on the odometer and get great gas mileage. Everyday driving I average 15-16 mpg depending on the foot. Interstate driving around 75 mph I hover around 20-21mpg. Towing a 10k trailer I get 13-15mpg depending on the terrain. Im very happy with my decision to get the 4.10's. However like many people have said you wont be happy with 4.10's if you like driving over 75mph on a consistent basis. She will be screaming and sucking diesel
Good Luck!!!
