What type of fuel should I use for my Infiniti vehicle?

For optimal performance and to ensure longevity of your Infiniti vehicle, we recommend using premium unleaded gasoline with an octane rating of at least 91 AKI (Anti-Knock Index). Premium fuel helps to maximize engine efficiency and power output while minimizing the potential for knocking or pinging. While some Infiniti models may be compatible with lower octane gasoline, using premium fuel is highly advised to fully experience the designed performance and efficiency. Additionally, using lower octane fuel may negatively impact fuel economy, engine responsiveness, and overall vehicle performance. It is important to consult your vehicle's owner's manual or contact an authorized Infiniti dealership for more precise fuel requirements specific to your model and year.
