Therefore, what one needs to do with a new car is to drive
the car at reasonable speeds and progressively pulling more revs
as the mileage increases up the first service, usually 1,000 km.
Try not to run for a long periods at high engine revs until
the first service as all new mechanical devices, however well
manufactured, will still have rough surfaces that need to be
worn down smooth.
