If it states "Premium Fuel Recommended," the minimum octane is acceptable, but premium may offer enhanced performance in specific conditions. Using a higher octane fuel than the manufacturer recommends yields no performance benefit, improved fuel economy, or reduced emissions.
Unleaded Gas Octane Rating Clean Agents Fact: Understanding Performance and Efficiency
Engineers calculate the optimal octane requirement based on the engine’s compression ratio, the shape of the combustion chamber, and the calibration of the ignition system. Conversely, economy cars with standard compression ratios are engineered to run perfectly on regular unleaded.
The result is then mathematically adjusted to match the performance of a blend of iso-octane (which receives a rating of 100) and n-heptane (rated at 0). Selecting the correct octane grade ensures that your engine operates efficiently, protects critical internal components, and delivers the performance promised by its design.

Always adhere to the manufacturer's minimum requirement. In reality, the energy content, measured in British Thermal Units (BTUs), is nearly identical across all grades of gasoline.
