Premium gas is a misnomer. Premium, plus, and regular are not value descriptions but instead are fancy terms for the octane rating. For high performance vehicles, use the right octane rating to prevent engine knocking and keep your car running smooth. For normal vehicles, plus and premium grade gasoline provide no added benefit and are not worth the extra expense.
