also remember that when there are fuel shortages sometimes states authorize the use of "winter fuel" in the summer. So i wouldn't be surprised that even if you do get premium fuel if it isn't performing up to normal standards.
I guess this happened at the beginning of covid. ZZP released a statement to it's customers warning them about the potential engine damage due to running the winter blend in warm months
