I missed it. Where is the fact in this statement?

Your going to ridicule with opinion?

Really?
Kids do that right?

Oh the irony........................

I hadn't thought of those possibilities. Any of them would kill the deal for me.

Same dealer has a very similar 2020 on the lot with 5 miles on it. The difference in price is $2200. It might be worth that for my peace of mind.

Totally worth it for that much money. Just the trade in/resale value would be worth that in a few years. (Not sure how long you keep your vehicles.)

Here's a though. Act as you wish to be treated.

Someone really important said that once.

Don't act so surprised when treated rudely if your rude.

I've never really "broken in" any of my new trucks. Just drove them normal.

Only car I've ever paid attention to the break in period is my '18 Grand Sport.. the tach pretty much reminded me the first 500 miles to take it easy.

Ok, plenty of experiences of trucks being driven with no regard to a break-in procedure. So why does GM put it in the manual? Is it a catch that they can use to deny a warranty claim?

Because i don't own a C7, how did it remind you?

It had a yellow and red line on the tach showing you the max rpms you should be going for the first 500 miles. The line went away as soon as I hit 500 miles.

I know that I am strange. I often read the manual for things before I buy them to be sure I don’t have any surprises.

Vehicles are on the list of items I research thoroughly before purchasing. The manuals for these trucks have always said for the first 500 miles don’t tow and to keep it under 55 mph. After that keep it under 55 for the first 500 miles of towing. Over the years I haven’t come across any car salesmen who know that.

I doubt that most buyers know that either. That leads me to believe most new trucks are not treated that way. The wording in the manual says it will perform better in the long run if these guidelines are followed.

How important is this? What does perform better in the long run mean?

Doesn't matter what break-in method you use. To each his own.

If you want to properly seat the rings, there is only one way & it isn't detailed in the manual.

You mean heat cycles? , or load cycles to create high cylinder pressures to seat the rings?

I wouldn't say you're necessarily strange. At my last company every time we got a new truck no one ever told us anything about breaking it in! Of course for a driver at first this seems very convenient and much easier than having to deal with the fuss of taking care of his truck for such a long time. Unfortunately this led most of the time to engine issues, and it's not a nice scene having your truck stopped out in the middle of the highway!
