breaking in new lnf motor 2009
You're gonna get about 1,000 different oppinions on this one. Some claim it's broken in from the factory, some say don't drive it easy just drive it like you normally would, and others will suggest like EXsoccer to take it easy. Personally I broke mine in by more or less taking it easy for the first few hundred mils but still got on it every now and again just to start seating the rings. How ever I didn't take it past 4500 rpms. From maybe 300-1000 miles or so I drove it even harder but still and didn't bring the rpms over 5,000 and only in short bursts still staying clear of the redline and didn't race it. Then after 1000 miles the motor should be pretty well broken in. If you do decide to take it easy, just don't overly baby it for too long. You can actually do damage if you drive it super light for an extended period, then start driving the **** out of it. But this is yet another of the 1,000 oppinions you will probably get.

I bought my SC with 295 horses on it I hope somebody beat on it before the first twenty miles. I know I did the guy who bought the new TC I test drove has a perfectly worn in seal. They let me beat the **** out of those new cars when I go test them for fun.
Not supposed to "beat the ****" out of it, but drive aggresively yes.
I followed those steps and I pull more vacuum at idle than when I bought the car brand new and after the first rebuild. Good vacuum is a healthy motor.

Drive it like you stole it is the basic answer. It's best if you can leave 2 smoking rubber lines in front of the dealership.
The manual says to vary the engine speed. Drive it anywhere between 1000 RPM to 6000 RPM!

i typically take it easy for about 500-1000miles, just drive like a normal human being. dont rev past like 3500, then after about 1000 miles or so, change oil. then start toying with it a bit. an occasional redline run. but in like 3rd so i dont risk hitting rev limiter in 1st since 1st typically spins real quick.
ss/tc ftwso i'm at about 23 in vac........ that means my motor is healthy?

I swear some people are retarded... The manual is very clear about the break-in procedure. GM engineers didn't waste that page in the booklet for fun, it's there for a reason.
Every time I see that website linked above I want to throttle someone... Seriously, some of you guys think that's legit?

I always take the easy break in approach and all my cars owned from new seem to last forever and not have problems and use no oil .The used cars I've bought all seem to have issues, use oil, and I have no idea how they were broke in. But answers like the ones here are the reasons I'll never buy a used performance car....AND of course this is just my opinion and the way I break in a car. The day I read in a new car manual from the manufacture "drive it hard for the first 1000 miles" then I might reconsider, but until then I'll take a car with less power because I easily broke it in. Isn't that what aftermarket parts are for?
My idea is that engines wear out no matter what, and have you ever changed oil on a new car? The first couple I did you can clearly see metal shavings, this is normal, My guess is that with hard driving during this time you would see even more shavings so my thought is that more shavings the more worn in it is = less time before it's wore out. Again just my opinion, my 2 cents, what have you. Maybe I'm being "old school"

OR
We take this statement into consideration and align it with this thought, Let's run each engine to our accepted break in period to know that the seals are made. And then when the customer comes in for warranty work we know it's legit.
You do that math.
i wouldt normaly go over 5k rpms but getting onto the highway ramps i would give some. Just dont baby it i guess but dont beet it up. Level it out kinda. And i would change the oil around 2500-3000miles instead of 5000 for the first oil change. after the firt oil change id say beet the crap out of it if you want.
I flopped between normal and spirited driving but always followed the recommendations in the manual. The important things to avoid are full throttle starts from a dead stop and driving at the same RPM range for an extended period of time. I'm not sure what my vacuum is at when idle but besides the occasional RPM and vacuum fluctuation at startup (this car seems to run the start sequence idle longer than most other vehicles) the car runs like a champ.
