Sarcasm is one of my strongest and best traits also!

Not like I’m worried about the break in period... just curious what others are doing. Sounds like I’ll be cruising by at 75mph give a jeep wave as I pass others.
Hi guys,
Got my new JLU 2.0 Sting gray altitude sport yesterday. Never had a new car before, always used. Came straight from the rig, had about 19 miles on it already.
Tried to follow break in procedure from manual but kind of impossible for me with work and all. I did baby the first 60mi not going over 50mph, on city streets and kept rpms <4k. However once I hit 60mi, I went straight highway, fluctuating from 60-80 mph not to exceed rpms 4k with brief WOTs. You all think that should be ok for break in or am I fudged...
Congrats on your JLU. Assuming you have the 3.6. You're fine. Just drive moderately for the next 300. You've done more to help your JLU than a lot of people. I've read some have driven it 100's of miles home from the dealer at highway speeds the whole time, never giving it a thought. Good job.
I will add this.... a former (Retired) Chrysler Engineer who raced in his spare time said this on breaking in an engine..." Its not the miles its the heat cycles". Most of us, even if its only got 2 miles on it, will have a broken in engine. Its been through its final shakedown, its been heat cycled properly. Take it for what its worth... I've varied my speed, and will be doing an oil change at 2500, then extend them from there. Not really worried about engine break in anymore.
Unfortunately unless you ordered it and are sure that no one else has driven it than it is more than likely to late to worry about with all the dealership studs and customers test driving it. The good news is, it is not a boat motor and a lot more forgiving.
Of all the new vehicles that are sold I wonder what percentage have had any specific care for a break-in period? I bet its much less than half the vehicles. So more than half the vehicles on the road should be failing prematurely.
