The fuel specification for a Toyota Highlander refers to the gasoline grade recommended by the manufacturer for optimal vehicle performance and longevity. For many model years, particularly those equipped with gasoline engines, the recommended fuel is regular unleaded gasoline with an octane rating of 87. Utilizing the correct fuel type is crucial for proper engine function and to prevent potential issues such as knocking or reduced fuel economy.
Adherence to the specified fuel grade offers multiple advantages. Using the recommended octane rating ensures the engine operates as designed, providing the intended power output and fuel efficiency. Doing so can also help to avoid long-term engine damage and maintain the vehicle’s resale value. Historically, understanding and adhering to manufacturer fuel recommendations has been a key aspect of responsible vehicle ownership and maintenance.
