Hi,
Is it safe to use Mercury Premium 2 cycle in my 1989 115 Merc? I seen some posts regarding to only use this in less than 25hp so am wondering if I should use it or not. I bought 4 gallons of this last fall. Or do I need the Premium Plus instead? What effect would it have if I use the Premium instead of the Premium Plus?

Thnx for everyones input.
