a quick question guys,in the owners manual they say that we have to drive moderatly during the first 3000km ,then the mecanics in the workshop said that these engines are preroded and no need to be smooth the first period ,personaly i made 500km under 4000rpm ,then went full blast.anybody know exactly anything about these first 3000km? does the fact to drive under 4000rpm for 3000km give the engine a better performance afterward?
