many years ago.. AMZOIL stated right on there package.. 25,000 miles or one year.
AMZOIL.. later changed there name to AMSOIL...
and dropped the 25,000 miles.
my Goldwing(1983) from 1,000 miles to 149,000 miles with oil changes every 25,000 miles and oil filters every 12,500 miles...
time was not factored..
never burned or used oil.

I ordered Amsoil for my truck, used it once and while I was doing it they dropped the extended range claim for diesel trucks. Have not used it since.
