Lightbulb Premium is considered 93 around here, 91. can i use "mid"

I was reading the gas mileage thread and it seems like people pay for premium in some places that is only 91 octane. In North Carolina, 93 is considered premium 91 is mid. Can i use 91 safely? it would save a few bucks and iit doesnt seem like it hurts any of you
