Hello,
I will be taking posession of an 08. Anything I should know about recommended (as in forum reco rather than dealer) break in?
Normally I'd go easy for ~ 500 miles or so. Brakes, clutch, keeping rpm within reason.
Can anyone share their thoughts here?

Thanks all!

 

The dealer will tell what is in the owners manual about break in. No big deal, drive it like you stole it.

 

sounds good tks!

 

The engine is broken in when you get it. The break in period is for the running gear. It's important to vary the speed for 500 miles.

 

Keep your foot out of it, for a while. That will be difficult. -- Enjoy. -- --

 

drive it hard, dont try to break it, but drive it hard. worst thin you can do is keep one speed for a long time, like getting on the highway for 10 hours would be bad

 

The break in period is to put heat cycles in the drive train. If you abuse it early on, you can have problems with positrac unit, gear whine, etc. This is no different than any high end performance car.

 

but you can listen to the stealing crowd,... and then we'll read about your problems with the car a few months from now!

 

Probably want to avoid the dragstrip for at least the first 500 miles.

 

Breaking this car in is a joke. Ya try driving under 55 for 500 miles!! I gave up after first run down the freeway.

I made two longish trips on some hilly winding roads varying the speed quite a bit.

I would drive on the freeway in fourth running it up to 70 and back down to 50 so on and so forth.

This C6 08 like to run especially with me behind the wheel.LOL

I really LOL when I read the 55mph part in the manual.

Impossible for 500 miles. I figure if your buying this car you won't have a chance of keeping it under 55.

 

I followed the recommended break in procedure. I drove the car from the NCM to VA with no problems. Vary your speeds, do not use cruise control. It certainly seems sensible to let the drivetrain and other machined parts settle into their natural wear pattern before putting a lot of stress on them. Congrats on the car!!

 

My dealer never mentioned a break-in

I ran it like I stole it the first day

Cars running stronger than ever 15K miles later, doesnt burn an ounce of oil between changes and cuts 1.9 60s on the base runflats.

 

Been discussed on here a million+ times.. so many opinions...

best to follow what GM says... they seem to know a little bit about these cars... They also need it to last and provide as little trouble as possible during the warranty period.. so one would think the info is valid.

It's not just the engine that needs breaking in.. it's mostly for the gears and brakes..
In general.. heat cycles are good for engine break-in.. vary rpm's and avoid abrupt starts and stops..

 

Drive it like you own it.

When you steal a car, drive that one like you stole it.

The paragraph in the owner's manual is the best advice, except replace 55 mph with 100 mph.

Everything else such as no full throttle starts, long idling, hard braking... all good advice. Nothing wrong with getting into the throttle hard, it only says no full throttle starts.

No possible way in heck is the engine broken in when you buy it. It will have a few minutes of run time on it. Someone want to explain the magic engine parts that are fully broken in within minutes. Every performance car I've had runs the best 1/4s and dynos after a couple thousand miles. Gee what does that mean, could it be that it takes a while to fully break in? Yes.

The fact that 99.9% will survive being driven like they are stolen when brand new is more a testament to the durability, moreso than that is what is supposed to be done. It can be pushed, no reason to tiptoe around gingerly, but things like ring and pinion gears don't like to see max load and max heat on day one.

 

The engine is not "broken-in" when you get it (30 seconds on the end of the line dyno does not equal a break-in), so it will appreciate some easy driving too. Take it easy as long as you can stand it.

 

a lot of different views, do what gives you peace of mind

I personally babied my car for 500 miles before I romped on it

 

Michrider... you are fast becoming one of my favorite posters on here...

 

We've all read the instructions and the word from the dealer saying vary the speed and keep the speed at or about 60-65 mph for the first 500 miles. And yes most of us do it. So, in goes my new forged 427 motor in my 05 Z51. A&A does the install and Charlie of RPM motors tunes it. They start the car, check for leaks, look at the oil pressure, and so on. They go out and put about 50 miles on the motor. Bring it back and strap it to the dyno and hammer it time and time again to the redling tunning the car. Results, It runs great, never had an issue, rings are seated and so on. That's how they broke in my motor,and all of the motors they build. So who's right? I don't know. Food for thought.

 

 

It's a difficult process, but you can do it. It just takes a little self control, and some concentration. Here's what you gotta do:

1) Immediately upon receiveing the keys, fire it up..verify delivery mileage, then give it some good tachs to redline to make sure it sounds good.
2) Everything cool? Before you pull out of the dealer, preferrably right near the front enterance, initiate a burnout. Make sure the tires get nice and toasty, you're going to need the traction to put all the power to the ground.
3) Time to go? Stay back about 25' from the exit, then when traffic clears drop the hammer and rip out of the dealer onto the street sideways..take it up to the posted speed limit, preferrably 55 so you can power shift 2nd gear (if auto, you may still get rubber into 2nd).
4) At your first stop light, do a 0-60 run..should take around 4.5-5 seconds depending on traction. It's ok if you spin the tires too much, you can always practice launch techniques more later.
5) After step 4, go immediately to your nearest highway, road course, drag stip, or other closed course. Once you get there, you need to do a top end run, just to make sure all components can handle it. Keep it down until the vehicle stops accelerating, thus reaches top speed for about 1 minute. This should be somewhere between 175-190 depending on wind resistance.
6) Slow down, pull over, stop and address anything that may have spilled or need cleaning up. Done..welcome to the C6 Corvette!! You should have about 30 miles on 'er by now..good to go..great job!!

Okay, so that's one end of the spectrum..just do anything BUT that and you'll be fine

Ok..so, this post is a total joke..but that's "driving it like you stole it" right?!!
