What kinda gas is best for a rx8?

The Mazda RX-8 is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. Using higher octane fuel helps to optimize the performance of its rotary engine, preventing knocking and ensuring smoother operation. It's important to avoid regular unleaded gasoline, as it may lead to decreased performance and potential engine issues. Always refer to the owner's manual for specific recommendations.
