Now that most gasolines whether Premium or Unleaded contains 10% bioethanol, do they really expire after 90 days?

My dilemma is I just bought gasoline full tank but since I'll seldom use it, I don't think I will be able to consume it in 3 months.

My perception is shouldn't all the major gasoline companies already place additives to prolong shelf life of the gasoline with E10 contents?

Or are the articles on the internet saying E10 expires in 90 days fake?
