I am sure this has been discussed but I couldn't find the thread I was looking for. I have question about the break-in. The first 500 miles are straightforward. I understand you aren't suppose to track the car until 1500 miles. The question I have is what's allowed in the 500-1500 range? The owners manual doesn't really specify what's allowed in this range at all. Some articles/videos say it's okay to accelerate and take it to red line just don't do crazy track days or launch from 0 mph. Other articles say you shouldn't punch it or accelerate aggressively or even rev the engine to redline in the 500-1500 mile range. Thoughts?
i probably had maybe 1500 miles or so before i even went above 4000k. But that's just me. I was in no hurry and my natural tendency is to preserve equipment. I now have just over 5000k miles and took it to ~7200 rpm a few times.
The 500-1500 mile breakin is for the DCT and rear gear in the transaxle, so using launch control or other full drag race/autocross/road course events should happen after 1500 miles. Take it to redline, use full throttle run the car strongly, just not full flat out either in straightline or doing max PTM runs.
This was for the C8 and I haven't read the Z manual but see below. I found that posted in 2021. Pretty good write up by a member and explains it clearly. If they didn't want you to use "full throttle starts" they would've said wait to use them until 1500mi instead of 500mi at least that's how I read it.
agree on tracking, but the manual doesn’t say anything about not using launch control until 1500 miles. From the owner’s manual under launch control:
Caution: The new vehicle break-in period should be completed before using the launch control feature, otherwise performance will be limited and damage may occur to the powertrain/engine. See New Vehicle Break-In page 192.
New Vehicle Break-In Follow these recommended guidelines during the first 2 414 km (1,500 mi) of driving this vehicle. Parts have a break-in period and performance will be better in the long run. During the first 800 km (500 mi), engine torque will be limited in low gears.
For the first 322 km (200 mi): . To break in new tires, drive at moderate speeds and avoid hard cornering. . New brake linings also need a break-in period. Avoid making hard stops. This is recommended every time brake linings are replaced.
For the first 800 km (500 mi): . Avoid full throttle starts and abrupt stops. . Do not exceed 4000 rpm. . Avoid driving at any one constant speed, fast or slow, including the use of cruise control. . Avoid downshifting to brake or slow the vehicle when the engine speed will exceed 4000 rpm. . Do not let the engine labor. Never lug the engine. This rule applies at all times, not just during the break-in period.
For the first 2 414 km (1,500 mi): . Do not participate in track events, sport driving schools, or similar activities. . Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal.
Since the caution in the launch control section says “performance will be limited and damage may occur” that implies that launch control should not be used in the first 500 miles when engine torque is limited in low gears. I think if you were not supposed to use launch control until 1500 miles, it would be included in the 1500 mile restrictions. All that being said, I have almost 600 miles on my car and I will wait until over 1500 miles before I try launch control, but I don’t think it is required.
So would you say that flooring it from a roll up to redline is okay after 500 miles or would that be considered "track like driving" and should be avoided until 1500?
The 4K limit was for the LT2 Stingray engine. Presumably the OP has a Z06 as he posted in the Z06 forum (but does not list what car he has, which would have been helpful). The LT6 500 mile break-in redline is 6500 RPM. Chevy recommends that, the tach recommends that and that is what I tried to adhere to once the engine was fully warmed up.
that's basically what I did too. Might have gone to 6k after 450 miles. At mile 503 the fun began.
I was actually pretty strict on the 5500rpm limit. It was hard though because the sound gets better with rpm’s. So many temptations during that Time but I’m glad it’s over. Can’t wait to drive this car again Saturday lol

The difference between bouncing 'it' off the RedLine and track use is oil temperature (220ºF versus 275º) not instantaneous component stress.

The confusion is the manual says 4000 RPM for break in (period). It doesn't specify Z06 versus Stingray like it does for a lot of things. I'm fairly certain that was just an oversight when adding the Z06 to the manual, but the only written statement GM has provided says 4k. That said, I, like most used the Tach as the guide, and I kept it out of the yellow for break in. Actually had to upshift manually a few times because the car wanted to hold gear, even under mild acceleration...
The car does not prevent you from running the engine to redline/FSO at 8600 RPM during break-in. The tach info is advisory. If you feel good about using only up to 4K RPM during the first 500 miles or only up to the tach yellow area, there is nothing wrong with doing that.

Can u not drive the car in Z mode till you reach the 500 miles ? Picking mine up tomorrow. It’s been getting tinted and full PPF. Haven’t driven it yet. It was delivered from the dealership to the body shop. Thanks Mine’s the rapid blue !!

You can. I did. In Z mode, you can select several variables like engine/shifting, braking and steering effort, suspension stiffness and exhaust tone. I would use one of the first two settings on engine/shifting to keep the engine speed down for the first several hundred miles. I left PTM (performance traction management) off.

That's gorgeous!
Man the front spoiler really makes the difference lol. I gotta get rid of my poverty splitter asap.

You will see that the tac LIMIT remains lower until after 500 miles. Vary speed, i.e. do not just run on the highway in cruise control. After 500 miles, start to DRIVE IT. This does not mean trying to go to the rev limiter but the automatic transmission is safe to take you however you want to drive. After 1500 miles, beat it up and have fun.
