The question of whether a specific vehicle necessitates higher octane fuel is a common one among vehicle owners and prospective buyers. The Infiniti QX80, a full-size luxury SUV, is often subject to this inquiry. Manufacturer recommendations typically provide definitive guidance on the appropriate fuel type for optimal engine performance and longevity.
Utilizing the recommended fuel grade can influence factors such as fuel efficiency, engine responsiveness, and overall vehicle maintenance. Adherence to the manufacturer’s specifications can help prevent potential engine knocking or damage that may arise from using fuel with a lower octane rating than suggested. Historically, luxury vehicles often specify premium fuel to maximize performance capabilities, reflecting advanced engine designs and performance expectations.
