How Long Until it is Broken In?

This is a tough question. When the truck is "broken in," fuel efficiency usually goes up as the indicator. A good rule is that under normal driving conditions (Driving to work, occasional medium load towing), 10,000 miles seems to be the magic number. More Severe use will acclerate the break in period while light use will prolong the period.
