Is higher octane gas better for older cars?

What happens if I use 91 octane instead of 93?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. Some manufacturers recommend premium gas but say that regular or mid-grade gas can be used instead.
