Popular Mechanics 關於new car care的文章,可以參考一下
"I customarily change the oil in a new engine after about 20 miles, and again at 1000 or so. That 20-mile oil, you would think, would look pretty much like fresh oil right out of the bottle. Wrong. It usually looks more like metal-flake paint, iridescent with tiny particles of metal worn off rubbing surfaces inside the new engines. After a few hours of operation, this completely normal phenomenon slows down as the rings, camshaft, lifters and bearings burnish their respective mating surfaces."
其論點為,更換機油是為了清除引擎磨合期產生的碎屑,作者甚至建議20 miles就先處理一次。不知道大家信不信,反正小弟是信了
