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?

I’m kinda like @KARNUT  in regards to break in. Every vehicle I have owned whether it’s been motorcycles, jet-skis, boat, cars, suvs, and trucks. I have driven them hard from the get go.  My jet ski

Maybe so but I like being the only one who's used it.

Absolutely unnecessary.  Not even remotely sound advice.

both i believe and depending if it was complete new motor or just top end....

Heat cycles really don't do anything for an aluminum engine. It's possible they were helpful for old school cast iron blocks waaay back in the day, but serve no purpose on modern engines. 
Load cycles are a different story. On any fresh engine, load cycles are the only way to get the rings seated properly & you have a narrow window of opportunity to do that - about 20-30 min when brand new.

If it is current why would that matter?

?

What do I mean by current?

It's a question that gets asked about what, every time a member buys a new truck?

Answer is the same no matter when it's asked!

 

Better question. Why does it matter to you?

You feel more relevant now?

ummm...the difference in potential results in the current flow?  I am currently reading Popular Mechanics circa 2011 when I am setting on the commode?  Hope, this helps where I currently stand?

New Chevrolet Corvette's engine torque increases after 500 miles (freep.com)

 

So the engineering staff at GM says break in your motor and believe in this so strongly that they physically limit the Corvette's rpm and torque limit for 500 miles! 

 

BUT

 

A bunch of forum Nimrods say there is no need? 

 

Someone is smok' n crack

:rollin:

 

Go ahead, tell me that the Corvette motor is made to a lower standard that requires archaic methods NO ONE needs to use anymore.

Someone can always be counted on for name calling. I’ve found with most new vehicles lately you don’t get max performance until they’re warmed up. My first one that did that was my 97 Ford 7.3. I wouldn’t be surprised if that’s part of the nanny systems today. Me I go with the Stacy David approach. I guess I’m a proud nimrod.[emoji106]

Well ain't you something now? 

 

In one breath you cry like a little girl about other people "thinking they know more than the OEM design engineering team" and in the...VERY...next...breath you throw those same engineers under a buss. ? Now you claim you know more than the engineers? 

:wtf:

 

Inconsistent? Ya think?

:crackup:

 

Guess that means you think you know more than anyone about everything. 

 

International Standard Version Genesis 10:9

.... "Like Nimrod, a fearless hunter in defiance...."

 

What's the take away here?

How about this...

 

No matter what the position taken is, you will defy it.

Not exactly name calling. More like a accurate definition. 

Not a boat you paddle alone.

Hence, Forum Nimrods.

Plural

 

Listen carefully. 

You are on permanent.... 

 

IGNORE. 

 

You've used up all of your get out of the dog house passes.

You have NO credibility left.

Not with me anyway.

Do you know who Stacy David is? He’s not a name caller either. Usually someone who is credible doesn’t resort to name calling or gets their panties in a wad. They just laugh and move on.

Isn’t it funny how a self described expert thinks GM is dead on with break in. And dead wrong with oil change intervals? Both have to do with longevity.

Welcome to the Grumpy Bear Permanent Ignore List Club. He's weak, imo. Can't seem to respectfully disagree.

Btw, this is the 72nd post of this thread and I'm somehow the first to provide the break in procedure for these trucks from the owner's manual. I didn't know there was a break in procedure. Why? Nobody said anything. What's the first thing you do when you're given the keys to a brand new car you just bought? You drive it home. For me, that was a 20 mile trip down the freeway at over 60mph. Maybe GM could've put this info on the Infotainment screen when first starting up and going through the procedure of setting everything up. 6d1186b0168a1b58c1b891c2654fa6c1.jpg

I see a lot of anecdotal evidence and opinion in this thread but not a lot of facts. I see a lot of personal attacks, name calling and unnecessary disrespect of other's thoughts and opinions but not a lot of science. (it's an open forum, I get it)

 

What I don't see, unless I missed it and if I did I apologize, are any facts or science that indicate the engineers that designed these vehicles are wrong in their break-in guidance. They apparently feel so strongly about it they are starting to use technology to force compliance (see Corvette story linked earlier).

 

So I respectfully ask, factually speaking, what is the downside to complying with the manufacturer's suggested break in period? Based on facts and science, what's the advantage of ignoring this guidance?

 

Again, I apologize If I missed the science based factual responses in this thread. They must have gotten lost in all the clutter.

 

JMHO

NO expertise implied or expressed

My 2 cents.

Whatever your personal method is to break in a new motor. I think you should change the oil and filter more frequently for the first whatever makes you happy thousands of miles. Simple insurance IMO.

I remember my first car. A Mazda RX3. I had my permit my father drove it home. My mother followed with her 73 Buick Rivera. The salesman said keep it under blah blah RPMs. He race a guy at the first light. It took my mother 20 minutes longer than us to get home. We went to 4 other uncles, brothers they had their turn. Speed shifting, redlining. Then the first week he drove it until I got my license. Later when I went to work for him. The guys all told me stories about lining up with him. I pretty much and everyone I know drive their rides from day one normal, meaning like they are going to. Saying that I’m not saying anyone should do that. You want to drive the highway at 50 mph during break in, do it. You’re ride. I don’t call people names doing what they do. I give my experience, I don’t dictate, like some. Or call people idiots. Some people will call some manufacturers advice as gospel when it suits them. Not when it doesn’t. I go by experience. And pass it on.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
