i just got an 08 with less then 800 miles on it and i was wondering what milage range did everyone start to notice that the car was broken in at?

 

after first oil change needed? i believe?

 

from what i kno 10k

 

Search knows...

 

as soon as you drive it off the lot.

gotta rough theses guys up a little

 

Drive it like you stole it from day 1 for a good, strong break in. I have 2500 miles and regularly hit 22lbs of boost. Don't keep rpm's constant, and make sure you run it through a few heat cycles before you drive at steady state rpm (highway).

 

clutch likes to be driven hard on this car.

 

First oil change and you're good. But before that you want to go through the rpms a few times just so the car is use to it because if you go easy for like 4000 and then beat on it you will break something

 

3000 aka first oil change for me.

 

i need an oil change. lol

 

I love all these different theories about breaking in new car. First of all, new cars are made to very tight tolerances so no real elaborate break in is necessary. "For the first 500 miles vary your throttle position and speed somewhat and avoid full throttle starts and engine breaking". Taken right out of nearly every owner manual I have read including the TC Cobalts.`

 

Agreed...why do people ignore what it says in the manual?

 

thats what i was saying...

dont do any high way driving..all city..get that throtle opened up all positons..give her a little gas but do dont any clutch dropping or anything.

 

Except you said it is broken in off the lot...not at 500 miles...

Also, don't go over 4,000 RPM until it is at 500 miles (I think it says this in the manual)...

 

to late...

im at 500 kms..been to redline a few times

 

what page in the manual dose it say all of this so i can read up?

 

I bought my car on a Monday w/ ~70 miles on it. Drove it 20 miles Tuesday, and another 20 on Wednesday. Then I had a slight problem where it wouldn't build any boost. Took it to the Dealer and they fixed it (loose adjustment nut on the wastegate actuator rod - no big deal).

Anyway, when I got the car back it had another 20 miles on it as they had to 'check' to make sure it was building boost. They checked it so well, that not only were my front wheels covered in brake dust (from repeatedly standing on the brakes from WOT runs), but my fuel mileage dropped from 24.5 to ~20 in the few miles they drove it. At that point, I considered my car to be 'broke in'.

FWIW, I'm just over 1,000 miles now and it runs great!

 

IDK, but beating that **** out of your car at any point in its life (especially during the first few hours of use) is not going to prolong its life that is for sure.

 

ya it doesnt say that in the manual, u just made that one up. lol

 

500 miles is what I waited for.

Don't beat your car period excessively...

 

i read that manual cover to cover (and its big) and theres nothing about 4k RPM... cars are made with VERY tight tolerances now compared to even 15 years ago, everything fits together so good theres not very much grinding like back then, this is evident just by looking at the metal in the first oil change in newer cars.... all that you'll have a problem with in any new cars is gaskets, once there heated and cooled a few times, your pretty much in the clear, BUT, its best to change your oil after the first 1k miles if your planning on beating it, just because any metal that did come off is debris in the oil now, and could damage bearings and whatnot while its mixing around in there, if you can take it easy to the first change... your DEFINATLY in the clear for all systems go!

 

buy the oil and filter from walmart and come to my house, ill change it for you in 20 minutes... i went to sears yesterday and got the socket i needed lol.
