Looks like a May end up driving quite a few miles from home to get vette. Are there any mph constraints on a zero mile car not broke in yet? Can it be driven normally on expressway ? I'd assume so but you guys know way more than me

 

I was told keep it under 80mph/4500rpm for the first 500 miles. I drove mine home to WNY from MacMulkin in NH.

 

Break in instructions are in the manual, available online via the above sticky. There are also countless threads on the topic.

 

You will notice that your tachometer red line will change at the 500 mile mark to denote the first tier of break in is complete. Video below, click to view.



From the owners manual:

New Vehicle Break-In
Follow these recommended
guidelines during the first 2414 km
(1500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
. To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km
(200 mi).
. New brake linings also need a
break- in period. Avoid making
hard stops during the first
322 km (200 mi). 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. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
For the first 2414 km (1500 mi):
. Do not participate in track
events, sport driving schools,
or similar activities during the
first 2414 km (1500 mi).
. Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2414 km (1500 mi).

 

I have heard 4500 max RPMs during breakin.
Redline is 4500, but owner's manual says 4000. So which is it?

I accidently shot up to 5000 a couple of times. Did I do any damage?

 

Engine is toast.....sell it quck!

 

As hard it may be, its best to drive like a grandma for the first 500 miles.

 

From the title of your thread, it looks like someone broke into your car.........

 

True dat.

(being too soft on things is about as bad as being to hard on 'em during break-in)

 

Thanks guys. Appreciate the feedback. I'll be in the expressway for 6 hrs. Hope the steady speed doesn't present a problem.

 

Just don't stay at any particular speed for more than 10-15 minutes at at time. Move it up and down 5-10 MPH or so....

(if an M7, change gears between 5th, 6th and 7th every once in a while too as long as you don't lug the engine or exceed 4K revs)

 

Here's a question: They say to stay out of V4 (4 cylinder mode). I was thinking touring mode did that. Later while in touring and changing speedo screens I come upon a screen that showed I was at that time in V4 mode. I was already over 1,000 miles so too late to practice that one!!!

 

Speed of the car isn't the issue, it's engine RPM. You can drive a constant speed for hours during break in, just vary the engine RPM by shifting.

 

What does "do not let the engine labor" mean?

 

What about the tranny? Can't hurt by varying its speed(s) and load(s) to establish more uniform wear patterns on the gears, no?

 

be sure to park facing down hill so the oil will stay in the motor then every 2hrs park the other way so the fluids can run to the back


joking ,all the advice above is good .enjoy the drive, be safe

 

Who is “they”? I’d be interested in you quoting something in the owner’s manual or GM literature where it says to stay out of V-4 mode. An A6 goes there much of the time unless you run it hard in manual and that won’t be a good break in procedure. Don

 

Change your speed and change your gear to vary your RPM. You'll be fine and you'll be smiling the whole time.

I picked my car up at the NCM and drove 800 miles in one day. I was headed to Florida after my pickup so what better way to break in the car....road trip! Did all 12 hours in one day. Could have gone several hundred more miles. Loved every second of it.

 

makes sense and thank you I will!!

 

Letting the engine labor means don't be in sixth gear at 30 miles per hour. You don't want the RPM's to drop so low that you are lugging the engine (you don't want to be travelling slower than your engine is trying to.) Don't let it drop below 1,000 RPM while driving
