Printed on the top of my colorful Amsoil cardboard shipping box is "SSO-04"
What does the 04 refer to? Does that mean there's also SSO-03 and SSO-02 , SSO-01 ?
Which is the best SSO?
This special "SSO-04" designation isn't found anywhere on the bottles, just on the cardboard shipping box in one spot.
