BREAK IN PERIOD QUESTION

[jmcbeth]

Here is a link to a GM video on the Zl/1 break-in period:



My dealer (Tom Henry) did not want to dyno the car until after the break-in period. I'm not taking any chances.

Ligenfelter team will make sure it's ready for use when the build is completed. They typically have a line of 25 vehicles waiting for upgrades and are very meticulous with all builds. My visit to their location outside of Frt. Wayne convinced me their a world class speed shop. My 2010 was on it's way there until they announced the the mfg release of the ZL1, immediately sold the 2SS and purchased a early build ZL1. It's currently at 2700 miles and makes fantastic power. Would like some additional torque at higher speeds and that could well mean a trip to Indiana. The 650 build is a great option for the money, enjoy.

Drive it hard, don't engine brake (no down shifting or coasting down in gear). Change the oil @ 500 miles. Seat those rings right!

Why doesn't GM build a machine that breaks in all cars they produce?

Per a GM Master Tech and Friend of mine.....

"The Factory Break-in period is for the owner's learning curve, not the Car, Drive it the first day the way you plan on driving it the last day....."

Grant this was a sedan, when i was touring the gm plant, cars were put on a dyno and did a full pull before leaving the plant.

Where is this written, it doesn't say it in the owners manual.

It's not written anywhere. It was something that some of speculated during the original break-in period arguments.

All we heard from GM was a statement from Fbodfather telling us that the decision was made by the engineers that designed the car, so they must have had a good reason.

Nobody has ever been able to figure out just what component of the car would require such a long break-in period. We just speculated ourselves that maybe, just maybe, the long break-in period wasn't for the car itself, that it was simply meant to be a learning period for the driver themselves, to give them time to get acclimated to the power and capabilities of this new beast before they unleash the full potential of it.

That is a big leap in terms of a speculation. My .02 is that people have their strong belief systems about how to break in a car and they aren't likely to change that based on anything they hear or read that says otherwise. It's rather extreme for GM to say not to exceed 4000 rpm for 1500 miles merely for drivers to get used to driving the car. I have a hard time imagining that.

Some dealers are easier to work with than others. I just don't want anyone taking the word of someone on the "forum" as gospel. I don't think the dealer will take "a guy on camaro5 told me it was alright. There is a lot of bad advise given out on the forum. It is everyones personal choice whether they follow it or not.

Over 38 years building race and street engines and I can vouch out of thousands, dont run it easy or you are setting yourself up for oil consumption issues and excess oil ingestion via the intake air charge .

Drink coolaide and believe the legal/marketing.management, or believe actual engineers. Your choice.

Are you advocating for people to violate GM's advice, they do have a few engineers too. There are some Dealers that have their own speedshop and will certify their work and meet GM's requirements. How would you feel if someone took your advice blew up their engine and the Dealer refused to cover it because the person violated the break-in?

Engineers don't write the break-in procedure; lawyers do. How many lawsuits do you think GM would face if they said that the engine needed to be broken in hard? Everyone and their mother would use the defense "the owner's manual told me to"

Do you really think they would ever promote break it in hard? I could see them dropping it completely if it wasn't necessary. If you had a brand new airplane and they recommended a break-in period would you violate that also because lawyers wrote it?

I have some tasty rat poison for everyone to drink, it is really good and helps you lose weight and lawyers wrote the warning about human consumption.
