yes and might be not
ppl claim engine still new like piston tight la etc etc
but u will never know what happen to your engine or car when it take from factory to your hand

No need lar. Just vary your speed, don't try to drive constant speed for too long. My new car terus sapu 140km/h - 160km/h. And i believe they have already run in the engine a bit at factory.

when my 2nd day got my car
i drive 170km/h at PLUS
end up, my car still running strong here

This is a practice done for more than decades ago. Newly manufactured engine might have splinters trapped in the engine. The engine oil which might carry loose splinters will be changed in a short period of time as a mean to flush out the splinters. Hence, new vehicle is subjected to services as it reaches the first 1,000km mileage.

Acceleration coupled with high speed travelling will caused the engine oil to rotate faster thus causing possible frictions between the engine inner surface and the splinters.

Hence, no "unnecessary" speeding please.

Listen TS, just drive like normal, ok? and service it on time. kapish?
