Is it necessary to 'burn in' or 'break in' a new car?

처리 내용

You should perform a new car break-in per the manufacturer's instructions. That way, if any warranty issues come up, you've done what they said to do. Generally speaking though (according to the engine builders I've talked to), you do want to vary the RPMs a lot, don't cruise at a steady speed for too long. None of them hold to the drive slow theory, nor the low RPM only idea (some of them do the initial break-in on the dyno with a series of WOT runs through the first few gears). More frequent oil changes are a good idea as a new engine will shed a little bit of metal at first. Usually it's something like initial break-in dyno runs, change oil, drive for 500 miles, change oil, drive for 1000 more miles, change oil, drive for 1500 miles this time, change oil, then onto your normal schedule.
