After seeing the insert bearings in a Model A engine with 20,000 miles on it and zero signs of wear on anything that moves or rotates, and it has only had synthetic oil in it since rebuild, I was sold. Everything still looked exactly the same as when it was assembled. Usually, you would see scrapes and scuffs on everything by then.
