yes but till 1000km its enough, after that fully synthetic oil is best for new engines, and modern engines hardly require any break in now days thats a thing of the past in cars of old technologies and the most important break in like of pistons, block etc is important for the first 100km and for few things first 50km which is already done in most cases before leaving the factory. after that its very limited that any more bedding in etc again will occur.
