The fuel recommendation for the Genesis GV70 varies depending on the engine. While the 2.5T engine can operate effectively using regular unleaded gasoline with an octane rating of 87, optimal performance is achieved with premium fuel, rated at 91 octane or higher. The 3.5T engine, however, explicitly requires premium fuel for peak performance and to avoid potential engine knocking.
Using the recommended fuel grade ensures the engine operates as designed, maximizing horsepower and fuel efficiency. Utilizing regular fuel in an engine designed for premium can lead to reduced power output and, over time, potential damage to engine components. The manufacturer’s recommendation is based on extensive testing to guarantee longevity and optimal performance under various driving conditions. Premium fuel’s higher octane rating resists pre-ignition, a phenomenon that can cause knocking and reduce engine efficiency.
