Previous owner said he used Merc synthetic oil but wasn't sure which. I'm guessing it's either premium plus, DFI/Optimiax oil or premium 2-cycle. I bought some Premium Plus but haven't used it yet. As far as I can tell Mercury says not to mix any oil with Merc racing oil. Am I good to go with putting Premium Plus in the reservoir with the curent oil in there?

Recommended by Mercury to use DFI on that engine. Let the tank go down low and can mix it in.

I had intended to mix about a 150:1 ratio of the premium plus in with the fuel as a recommendation for injector lubrication so I figured I would use the same in the reservoir...?

I use premium plus in my Opti Pro XS only. DFI is too expensive and unnecessary but they want you to buy it and that's why they strongly recommend it.
