Will 87 run in this engine? Will it harm engine? Will it harm mileage per gallon?

These cars require premium to get all the horse power that it really has, but u can use 87 may feel just a little less powerfull not a whole lot. But u will save money now with high prices man. And well these cars have enough horses anyways even with 87.
