Location: Twin Cities, MN | Hi,
I have seen this question a few times on BBC, and from what I have read, Mercury/Quicksilver Premium PLUS and Mercury/Quicksilver Optimax/DFI oils are compatible with each other but in general you should stick to the recommended oil for your Pro XS.
Did you perhaps disconnect the oil line ? If so, I think you need to perhaps bleed the line.
As far as fuel additives, I use the below. It has been good to me for years, although I do not put any corn gas in my boat anymore after a bad experience with it.
For each 5 gallons of gas --
1oz Mercury QuickCare
1oz Mercury QuickLeen
Good Luck
