If that is the case are there additives that you can add yourself to the engine oil to replace what they took out???From an engine builder's website - makes sense to me:
"Break-in oils have existed long before the flat-tappet cam break-in fiasco of the mid-2000s. There is even a chapter dedicated to break-in oils in the “SAE Lubricants Handbook.” It was commonplace for OEMs to use break-in oils before car leasing became popular. As the EPA fuel economy requirements tightened, the need for less maintenance and better fuel economy ended the use of break-in oils as factory fill in new vehicles. "
