Advice on breaking in a brand new Paccar MX engine on flat lands please

and no cruise control.....at least in my case

 

I've run cruise with no issues.

 

you have cruise control when you start engine very fast without this 30sec?

this is good trick to make you to wait this 30sec no one want to drive without CC

i know one trucks with over 60 codes on first service all related to starting

 

My dealer never told me anything about waiting to start when I first bought the truck. So I'd start it like any other truck of mine. I put on 450hrs like that and the cruise worked every time. No codes either.

However I did get told to wait 30 seconds after my truck started throwing codes and they were trying to implicate me instead of a Paccar fail. Never the less it wasn't my fault.

 

In that case Drive it Like You're late for Mass!

 

An hour here and there won't hurt it as long as you drive it. I have a 2016 with 37,000 miles on it right now. As long as you limit your idle to less than 20% or as close to 10-15% as possible a few days won't hurt anything.
