625 miles run-in time are enough
as the rule says "1000 km" in km-counties ...
As far as I know VW said for the Lupo 10 years ago: NO run-in time!
I had to make 200 miles on German motorways back home - and this is impossible/dangerous with 50 mph! I drove 60 mph and sometimes 75 mph ...
A run-in time only makes sense, when you change the oil after the 1000km (or miles)!
Motorbikes still have a run-in time and they have the first oil change after 100 km/miles.
The tiny run-in metal which is in the oil has to be removed.
It makes no sense to drive the car carefull and then (with the metal pieces left in the oil) run the car on full speed. These metal parts in the oil could damage the motor anyway.
Okay; for many motorbikes it is normal to run them at 5,000 rpm, 7,000 is still normal and the red area begins at 12,000 rpm. But it is also the way of manufacturing the motors. Cars are meanwhile built for stupid and careless drivers!
MORE IMPORTANT ...
than the rpm is the acceleration to me ...
You can drive your new car at 75 mph as long as you accelerate gently.
To my mind a kick start with putting in the next gear at 3,000 rpm every time is more poisoness that the speed. A slow increase is better for the motor.
