The 2017 Toyota Corolla is designed to run on 87 octane regular unleaded gasoline or higher as recommended by the manufacturer. Contrary to popular belief, using a higher octane fuel than what is specified in the factory settings does not provide any significant advantages for your vehicle's engine. While some may claim that using a higher octane fuel can improve gas mileage or help keep fuel injectors and the fuel pump in good condition, these assertions have been proven to be untrue. If you experience hesitations when accelerating or difficulty starting your vehicle, you can purchase fuel pump/injector cleaner from an auto repair store to remove any buildup that may be affecting fuel delivery and causing performance issues.
Toyota suggests using a minimum of 87 octane regular unleaded fuel for the 2017 Corolla.
