Because of this special anti-wear chemistry provides by these additives found in the conventional oil, break in oil provide an extra level of lubricant that aids the break in process and allows for the engine to become fully functional without placing extra stress on its load bearing parts. Although it varies by model and engine type, the break in process lasts anywhere from 500-1,000 miles. Once that distance has been reached, your engine will be ready to use regular oil and break in oil shouldn’t be used past this point.
