Should the Land Cruiser use 92 or 95 octane gasoline?

The Land Cruiser should use 95 octane gasoline. The fuel grade corresponds to the engine's compression ratio, which can be found in the vehicle's manual. The higher the engine's compression ratio of gasoline to air, the more complete the combustion at the moment of spark plug ignition, resulting in stronger power conversion. The Land Cruiser has dimensions of 5095mm in length, 1975mm in width, 1930mm in height, and a wheelbase of 2850mm. It is a 5-door, 8-seat SUV. The vehicle is equipped with a 5-speed automatic transmission and a 4.0L V6 naturally aspirated engine, delivering a maximum horsepower of 275ps, a maximum torque of 385nm, and a maximum power output of 202kw.
I've been driving a Land Cruiser for several years, and as a frequent family vehicle, I usually fill it with 95-octane gasoline. The manual clearly recommends higher 95-octane fuel to reduce the risk of engine knocking. Although 92-octane is cheaper, it may damage pistons or increase fuel consumption in the long run. While 92-octane is easier to find in remote towns and saves money, the Land Cruiser's engine is highly precise. Using lower-octane fuel for short trips is fine, but long-distance driving can accelerate aging, making repairs more expensive. I suggest new owners follow the manual directly and not experiment to save money—engine seizure would be even more troublesome. In reality, the difference in fuel consumption is minimal, and 95-octane improves power stability. Safety comes first.
