How Did You Break Yours In ?

[191185]

I just passed the 500 mile mark on my 2010, I didn't go past 3k rpms during that period, but shortly after, I brought it up to 4k rpm a few times on the highway after the engine was up to temp

 

Does that sound about right ?

 

 

At what point did you first bring yours up to the rev limiter if ever ? when did you start getting close to 6k rpm's and is that ever good for it during the break in period if you plan on driving it hard with towing and boat launching it's whole life ?

 

thoughts .. . .

I didn't even break my truck in, I hit the speed limiter a few times the 2nd day I got the thing.

 

They build things alot better than they did in the old days.

 

Im willing to wager my truck lasts as long if not longer than some trucks that people have "broken in"

For break in I left the dealership went home and hooked up the trailer then drove from lake erie to atlanta.

your engine is pretty much broke in by the time it gets to you. on the way home from the dealer i drove mine like it was a rental. I changed the oil at 500, 1000, 3000. and then every 3000 since. enjoy the new truck

Modern engines are quite different than the past. A "Break In" period is really not needed. Though, if you do want to ensure longivity the best recommendation is to ensure that your engine reaches full operating temp each time you run it for the first few weeks. Partial temp warm-ups and cool downs cause the metal structures to not reach their full potential. I too just pasted the 500 mile mark on my new 2011. A couple times during those miles, I did have short trips, but I made sure to leave the engine running long enough to reach the 210 degree mark before shutting it down.

 

P.S. my father was an engineer for the U.S. Air Force for 46 years. His specialty was metallurgy. Especially the longevity of engine parts in airplanes. SO my info comes from a highly reliable source

Drive it like a rental, got it.. .

I turned the key and drove it off the lot like I stole it. Never looked back. I changed the oil at 1500 and now every 3000 no matter what the oil life monitor says.

break in...we don't need no stinkin break in.

 

LOL

The break in procedure is provided for you in the owners manual. That's all that is needed.

I stayed off the throttle a little for the first 100 or so miles and then drove her like I do normally. Did the 1st oil change around 400 miles

Modern engine are NOT hot tested at the engine plant, all that is done is turned over for a minute by an electric motor whil some tests and final balance are done. The first time its started is at the end of the vehicle assembly line and driven off the line. A good break in requires heat cycling of components and seating in of parts. It states that you should not TOW or work the vehicle until 500 miles has past.

The end result of not doing a proper easy break in is long term reliability.

It's not just the engine breaking in. Consider the break-in period usually suggested when you swap in new differential gears, which are usually broken in for 500 miles at varying RPMs with a suggestion to swap out the diff fluid after 1K or so to get rid of metal shavings.

The first day I hit the governor, my dad did, and my buddy did!

And the people that dont do a proper break in are the first to complain about the problems they have with there vehicles.

Drive it like you will for the life of the truck, that is the best that I can recommend.

 

I ALWAYS bring a new engine to operating tempertures BEFORE getting freaky on the throttle. As

I still do for the life of the engine. Doesn't matter if its a lawn mower or a $50k race engine.

They then get used like they would at any other time weather that be at an idle or wide open.

 

If you only knew what your vehicle goes through for it's first 10 minutes of life you probably wouldn't buy one.

I watched CTS-V's in DVT at the plant go wide open for 2-3 minutes after 5 minutes of initial engine run time.

It's the second test after they come off the line. Wheel alignment is first.

 

Nothing like hearing that SC whine.........
