Opti Max Oil

[PtownBubba]

Is there a difference in these oils, I have a 2006 75HP Merc OptiMax,,, Quciksilver 92-858037Q01 vs Mercury Marine 92-858037K01 DFI 2-Cycle Oil ???

Can Iuse the Quicksilver Brand in the Merc. ? Since Quicksilver is sorta' a Merc product ,,right ?

Mercury strongly recommends the DFI oil in OPTI models but it is your choice of which oil you use.
