I am curious what others are getting with a 3.73 rear end with the EB?

I had a '13 supercab EB with the 3.31 and traded it in for a '14 supercrew EB with the max tow 3.73 rear end and my MPG's are down about 2.5.

I'm averaging 15.5 now, before it would be 17.7-18.

My lifetime average (26k kms) is 15.8 L / 100km (15.6mpg). Mostly city driving, a lot of short trips, and cold weather from October to April.

It is getting better as the weather warms up, but stop & go traffic really hurts.

23K miles, my lifetime average is 13.1

Most of my commute is highway and I consistently get 20+ out of mine. If I do a lot of around town stuff I fall in to the 16-18's. I'm not what you would call an aggressive driver though.

MPG is so very dependent on driving style..........my wife gets around 12 to 14 in town, while I can easily get over 17/18. Coasting up to red lights and not having to accelerate back to speed every time makes a huge difference with the little EB.
It is after all only 213 cubic inches trying to accelerate nearly 6,000 pounds up to speed. It doesn't take any boost to maintain city speed, but I'll bet it takes a bunch to get the truck back up to speed from a stop.

The 17/18 is also what I'm averaging around town. I'll get over 19 on the highway. It drops down when a trailer is following me.

I'm getting around 18 pretty regularly with about 70% of that being hwy. Since I bought it I've put 5000 miles on it and the average for that is 17.2

This current tank I've been doing ~75 on the hwy and it's still getting 18.
