switching oil while running in

[oxo]

Hi,
Can anyone tell me if it's ok to switch the 2stroke oil already mixed in the tank( about 40l of fuel worth) from quicksilver premium to quicksilver premium plus while running in a motor? I'll be putting in about another 60l of fuel plus oil so was wondering if the two oils mixed together ok? And if it's crucial to keep to one oil while running in?
Still being very careful!!!

I would never mix different blends of oil dude. Also if it was me I wouldn't use premium plus to run in with as it won't have as good an effect as its a better quality of oil

Ok,
Many thanks
