Too Afraid to Ask

Premium fuel is a higher‑quality gasoline that some cars need to run best. It has a number like 91 or 93 and helps the engine avoid knocking.

Technical Definition

Premium fuel is gasoline with a higher octane rating (typically 91 or 93) that resists knocking in high-performance engines, allowing them to run more efficiently or produce more power.
