Re: 3.73 -vs- 4.10 rear end MPG difference on a 6.0?
The 6.0 likes the 4.10 better for towing. I went from a '03 3.73 6.0 to an '05 4.10 6.0 and there is a world of differance when towing. I am running a 6 speed in both trucks.
As far as mileage it all depends on the right foot. I have seen as much as 17 mpg (hand Calculated) running empty but overall average of about 15 mpg (city and highway combined)is most common and towing 12,500 plus I see about 12 to 13 mpg just depends on the wind and if I get caught behind a gasser (motorhomes, V-10's, Hemis, etc [img]/ubbthreads/images/graemlins/blush.gif[/img] ) that thinks he has got the power to pull the long grades here in Alaska.
