Default Fuel economy vs gas octane

Hi everyone, since the gas prices are getting high I was wondering if there is any change in the performance of the truck and in the gas consumption if I use 87 octane gas or if I use 92 octane gas. I have the 5.7 Hemi, and as far as I know it shouldn't be any problem to the engine, but again, my concern is about the mileage
