Synthetic oil basics. Why is it better?
AMSOIL is a full synthetic man-made product made in the USA. Not a "hydro-cracked" base crude stock like those made by commercial companies claiming to be "fully synthetic". In actuality, their oil is derived from crude oil, manipulated, and given the approval to claim "full synthetic" by order of a mandate initially started in Europe that eventually influenced the American Petroleum Institute to back up the definition of what a true synthetic oil is.
