They recommended an oil change after 5 hours on my lawn tractor for similar reasons. But I know nothing about whether the new technology they are using on the engine will supersede that need for a quick replacement oil change. I haven't heard of doing it on a typical new car.On break ins... I remember reading something years ago about Russian diesel tank engines, and that it was "normal" to remove about a kilo of shavings from the crankcase at the first oil change.
