The "must use dino oil" break-in myth has as much truth to it as the old "must use non-detergent oil" myth from the 60s and 70s. Consider that many newer cars come from the factory with synthetic oil--this assumes of course that the engine was re-built (mostly the honing of the bores and fitting of the pistons/rings) by a reputable shop...
