try not to rev your engine above 3,000rpm. follow this ritual for the 1st 1,000km (which is normally the 1st service)
right after the 1st service ....... push your car. take it close to red line if you want
i did this to 2 new cars, and the engines were smooth and powerful till now ....... read this tip from a car magazine. can anyone verify whether what i do is indeed a workable thing?
the magazine's explanation was that it had something to do with the engines walls being rough when new. and then after the rough edges have worn off ...... then, only rev it higher. else, unnecessary wear and tear. and then, after the 1st service ...... the oil is clean, so rev it high to smoothen out the walls ........ something like that
well ..... it worked twice for me
