[QUOTE="UnleashedBeast, post: 14310585, member: 112023"] AMO's base oil is superior, to an extent, as it's 100% true synthetic. However, XLO has a superior, more modern, additive package. XLO is a blend of group III+ and group IV, with more group IV than group III+. NOACK Volatilty is still less than 8%. Off the shelf group III base oils have more than 10% NOACK, suggesting higher amounts of group III base oil. AMO is old school when it comes to the additive package. High ZDDP and no friction modifiers (that part is significant). XLO has API SN levels of ZDDP with Moly and Boron used to compensate, and friction modifiers. UOA results with XLO are impressive, proving that modern day engines no longer require boat loads of ZDDP for protection, as modern additive packages compensate in other ways, which prove more effective. Summary, sacrificing 1% NOACK volatility due to a small amount of group III+ base oil......to gain a superior, more modern additive package.....is a no brainer. Especially since UOA proves it.
