less protection to squeak out a fraction of a mph fuel economy increase to meet fleet CAFE standards
xW-20 oils are commonly required now. Toyota is moving towards xW-16 and development of xW-12 and xW-8 are underway. All of this risking increased wear and tear on engines, differentials and transfer cases.
