What mills? It has served me well for many years in my engines. Currently running it in a 496 MAG.

None that I know of. Boat had over 20 hours on it when I bought it from Majic Float. (It was Formula's photo shoot boat) I don't think yjey were running synthetic. I have 110 hours on it now and still running strong. I've been using 20w50 since new but it's getting harder to find. Change oil every 30-35 hours. I have no problem going to 15w50. Thx.
