The capacity of the receptacle that holds gasoline in a Toyota 4Runner is a critical specification. This measurement, typically expressed in gallons, dictates the vehicle’s potential range before requiring refueling. As an example, a larger measurement allows for extended journeys without the need for frequent stops at filling stations.
Knowing this volume is essential for trip planning, budgeting fuel costs, and understanding the vehicle’s capabilities in different driving conditions. Historically, this specific dimension has evolved across different model years of the 4Runner, reflecting advancements in automotive design and efficiency considerations. Understanding this aspect also informs decisions about fuel grades and overall vehicle maintenance.
