[QUOTE="UnleashedBeast, post: 11828212, member: 112023"] CAFE laws, and no other reason. The bean counter want to pay less fines to the federal government. Royal Purple HPS is a true synthetic base stock which naturally has a lower NOACK Volatility (evaporation/burn off). It evaporates 50% less than Motorcraft 5W-20, so what means having a higher level of ZDDP (Zinc and Phosphorous) will not be any more detrimental to your cats than Motorcraft 5W-20 with lower levels of ZDDP. Phosphorous is poisonous to catalysts. [/QUOTE]
