Is premium the same as non oxygenated fuel?

No, premium fuel and non-oxygenated fuel are not the same. Premium fuel refers to gasoline with a higher octane rating, designed to prevent engine knocking in high-performance vehicles. Non-oxygenated fuel, on the other hand, is gasoline that does not contain oxygenates like ethanol, which can be used in specific applications or engines that require it. While some premium fuels may also be non-oxygenated, the two terms describe different characteristics of fuel.
