Get that oil out ASAP.. The ability of the oil to neutralize acidity is most likely depleted.
As stated above, Change oil and filter with a Motorcycle oil or any oil with a JASO MA Rated oill.
You can use an auto oil but be sure it has an API SG/SH Rating.. Not higher
I would recommend, to stabalize a full tank of fuel and while running it to get the stabalizer through the system, fog the engine when it is warm. Then change oil and filter and Do Not start the bike after that. This introduces more acidity in to the oil.
