Geez you guys, at my age I don’t remember what I did last weekend let alone what I was doing with my ‘76 F-150 forty years ago. That one was broken in with maybe 40 thousand on it as I never kept anything much over a hundred thousand back in those days. Now I just get rid of the “old” oil at way less than 10,000 miles. Amsoil I’m sure has changed their formulations some since I used it and I know that the Mobil 1 oil that gave me trouble in the Saab has been made much thicker since it first came out when I used it.
