Over 6180 miles its gotten a worst of 18.3 US MPG (12.85 Liters per 100 km) and a best of 20.9 US MPG (11.25 Liters per 100 km). The majority of the tanks are in the 19's (12 Liters per 100 km). All mpg is hand calculated as it doesnt have EVIC.
PS the Limited Slip 3.55 Combo became available on Regular Orders with the introduction of the Tradesman. I believe its always been available as a Fleet Order. If you are installing a limited slip in an existing truck with the 9.25 the Eaton Detroit Truetrac is a better option. Its a stronger, torque biasing, gear driven (no clutches to wear out and no friction modifier required), and more effective. Unlike a locker its very streetable. If you are buying a 2012 with the new rear end you will have to go with the factory limited slip as its the only game in town as of now.
I am guessing you do a good bit of highway driving.
I have 3.55s in my truck. I wish I had the 3.92s. There are so decent size hills where I drive and I driver about 80% in the city. If I mainly drove on the highway I am sure I would love the 3.55s that much more. I am thinking about a regear though.
