Re: Is this Fuel Mileage what it should be.
The 4.10 and automatic is the stronger combo to own. The manual transmission with 3.73 axle will get better mileage as there is less drive train loss over the automatic, despite the one additional gear for the manual there is still only one overdrive gear per transmission.
If you change fluids to full synthetics in the engine, and rear axle, you might gain 1mpg as it will lower friction on the drive train. If you have slightly aggressive all season tires or all terrains on the vehicle that will increase aero drag and lower mileage. Hence why most manufacturers put cheap tires on their vehicles that offer no traction to up their MPG numbers.
