the what? Two oils?
Well I dont even know what a NSR honda is, but if it says oil in the thing, then it is possiable. Or if somone tinkered with it, they may have reversed it prior (iv done that on pw50)
But as long as it says oil, and says its for 2 stroke or somthing, then Id put it in there, but if its some how the gear oil, then dont!
