Premium gas typically costs more per gallon than regular gas, with a price difference of about $0.25 to $0.50. It’s recommended for high-performance or luxury vehicles that may benefit from the higher octane rating. For most standard vehicles, regular gas provides sufficient performance and is more cost-effective.
