Break-in period?

In the 2004 4.4 sport, I could hit over 100 between OKC-MEM then parts of MEM to Nashville. However, once at MEM then esp Nashville on to Knoxville and parts of NC, etc., there is a lot more congestion so I can't use cruise as much as I like or drive as fast as I want.

Anyway, in terms of the next 1K, these miles will be mostly on open highway and it would be a real problem to vary speeds and reduce the use of cruise but if that's what it takes then maybe I need to add another hotel stay at least going.

But am I being told to worry about the entire trip? There will be some city driving in between the first half of the trip and then the return home, but maybe not enough to really make a difference in terms of what we are discussing. Do I need to add another hotel on the way back? Does driving a shorter distance on a given day make a difference over going as far as we can tolerate?

Don't make too much of it, def don't modify your trip because of this. Just do what I said as many times as possible before the trip. That's the way to break-in a new engine regardless of circumstance. Ideally you do it at 0 miles, but it's pretty fairly young.

Btw, to warm up the engine just drive around normally. Do not let it wam up idling.
