With the Advanced HC/HI (115 VI) and the Synthetic HC/HI (125 VI) base oils, iso- and mono-cycloparaffins ranged from 76% to 91% and approached the 100% level observed with PAO's while being significantly different from solvent-refined base oils which contained 45%-50% of this group and only 25% iso-paraffins.
