Which Amsoil Oil do you use?
I just switched to the 15W-40 Diesel-Marine oil and the Amsoil EA oil filter about 5k ago. Engine does seem to idle/run smoother and a bit quieter. Going to save me some serious $$$ in the long run if the oil analysis allows to go 15-25k mile oil change intervals...
What interval is everyone changing theirs at?
