I'm currently sitting at 52K miles, and at 46K I changed the oil to AMSOIL with an A\C Delco filter. The oil life percentage is at 3% now. How far has anyone here gone on AMSOIL? Using their oil in my prior gas or diesel trucks, I'd routinely push 15,000 miles on one change, with nothing negative to show in the oil analysis results.
