What grade of gasoline does the Wildlander use?
2 Answers
Toyota Wildlander's official recommendation for all models is to use 92-octane gasoline. The standard for fuel selection primarily depends on the engine's compression ratio. Introduction to gasoline grades: It represents the ratio of actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane number, the stronger the anti-knock performance. Composition of gasoline: Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties, with its octane number defined as 100; n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane number defined as 0. Selection criteria: The primary criterion for selecting gasoline grades is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles.
As a long-time Highlander owner, this vehicle should use 95-octane gasoline. The Highlander's engine has a high compression ratio, around 10 or above. Lower-octane fuel can easily cause knocking—that stuttering sound from the engine—which can damage the engine over time. I've always used 95-octane, and the ride is much smoother with quicker acceleration response. Although it's a bit more expensive, it saves about 0.5 liters per 100 kilometers in fuel consumption, so the actual cost difference isn’t significant. Remember to check the owner’s manual—it clearly recommends 95-octane, and there’s also a label inside the fuel filler cap. Using 92-octane in an emergency is fine, but don’t do it long-term, as it can lead to more carbon buildup, making cleaning more troublesome. Always refuel at reputable gas stations for stable fuel quality—don’t cheap out at small stations to avoid impurities.
