As many of you know I picked up my truck on Tuesday and have been letting the wife drive it around town for the past week. My question is what is the break in period and when should I start to see a MPG increase. Right now I'm lucky if we see 12mpg. I have not had any of the TSB's completed on the vehicle yet (mirrors or transmission).
Mine is the EB 4x4 with Heavy Duty Trailer
Hoping I will get close the at least the 17's people have been getting
