  • I have a question about engine break in

    Is there an acceptable manner as to how you properly break in an engine of this magnitude. I'm going to pick it up in Maryland and drive it the 250 miles back to Long Island

    Just avoid using cruise control or driving at one constant speed, and you will be fine. The traffic on I-95 makes it likely you will be varying the throttle setting a lot as traffic speeds up and slows. Avoid full throttle or engine revs over 3000-3500 rpm for the first 500 miles.

      Stay off the freeways! I'm picking one up from Mike too. However, I'm driving it to Montana. I intend to take a couple weeks to do it while avoiding as many freeways as possible.

        In the olden days, it was recommended to not exceed 50 mph and don't maintain a constant speed for the first 100-500 miles or so. Don't remember exactly. I do remember it was a PITA. Haven't seen these restrictions on any of the new vehicles I've bought since 2007. Others here probably have recent Corvette specific info.
        Save the wave.

          Keep in mind you are breaking in the entire drivetrain and bedding in the brakes, too.

            Ive picked up a few new corvettes from dealers far away myself. I would suggest treating the vehicle like you own body waking up in the morning..as far as the brakes amd suspension are concerned.

            As far as the engine? I too am picking up the corvette from Mike in maryland and driving back to northern NJ...which probably means Ill take the same highways probably varying chosen gears from time to time to vary the engine revs a bit probably not revving beyond probably 4000 Rpms unless Mike tells me otherwise....(if the strike ever ends)..and with the 8 speed dct that should be easy...every so often ranging in gears 4,5,6,7. And 8...all depending on where the gears and speed land in the c8...maybe i wont even use fourth as I roll on down the highway....itll be weird doing so with the paddles.

            id imagine the speeds will range from 55 to 85 mph depending on traffic flow...

            should be easy to do as I take the ride home.

            all I can say from past experiences its a glorious ride home to enjoy ...

            its an epic adventure for-four or five hours.

              Follow GM's instructions, which will probably be the similar to the C7:
              • 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.
              • 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. 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 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.

                    My post, directly above yours, is from the C7 manual. The "no constant speed" is there.

                      I was driving my last new car all over the place to clear that condition as quickly as possible -- looks like it'll be the same for the C8.

                          I would have thought they bedded the brakes of every C8 at Bowling Green during shakedown/test runs. I recently did my daily driver with new pads and drilled rotors and it only took a few miles of heavy on and off braking in the proper sequence to bed the pads. They got seriously smoked when I did it, but when they cooled and ever since they don't fade at all.

                              Oil changes are per the cars automated system. I believe engineers have said the first service will be around 5k or 7k. I forget which. It will also include tranny fluid.
