Toyota Highlander cannot use 92 octane gasoline. The manufacturer specifies that it must be filled with 95 octane unleaded gasoline. Taking the 2020 Toyota Highlander as an example, its body dimensions are: length 4890mm, width 1925mm, height 1715mm, with a wheelbase of 2790mm and a curb weight of 2080kg. The 2020 Toyota Highlander features a MacPherson strut front suspension and an E-type multi-link rear suspension. It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 220PS and a maximum power output of 162kW, paired with a 6-speed automatic transmission.

As a seasoned long-distance driver, I've owned this Highlander for three years and have been using 92-octane gasoline without any issues. The manual clearly states: 'It is recommended to use fuel with an octane rating of 92 or higher.' In actual driving, the engine runs smoothly with no knocking or power deficiency, and I save a few dozen bucks on fuel costs each month. However, I should mention that during extreme summer heat, if refueling too frequently, there might occasionally be slight knocking sounds, so I usually switch to 95-octane occasionally during scorching seasons. For routine maintenance, regular checks of injectors and filters are crucial to prevent carbon buildup affecting fuel efficiency. Long-term, Toyota engines are known for their durability, making 92-octane completely viable—just follow the manual for the most reliable guidance; there's no need to spend extra on premium fuel. Remember, maintaining consistent fueling habits is key—avoid frequent switching between grades.

I handle cars a lot in my line of work and have noticed that the Highlander's engine design is quite flexible, allowing it to run on 92-octane gasoline. Octane rating refers to the fuel's anti-knock performance, and 92-octane fully meets the needs of regular driving. The manual also clearly states that it's not a problem. Only when you frequently drive on mountain roads or stomp on the accelerator will there be a slight impact, but the engine will self-adjust through sensors to prevent knocking. Using 92-octane daily is both cost-effective and safe, as it’s significantly cheaper than 95-octane—saving you a few hundred bucks over 10,000 kilometers. Small savings add up over time. During maintenance, it’s a good idea to check the spark plugs and clean the fuel system to prevent impurity buildup. In short, don’t worry about 92-octane harming your car—Toyota’s durability is well-known. Just follow the manufacturer’s recommendations. Adding a quality fuel cleaner can improve combustion efficiency and is also better for the environment.

As a budget-conscious car owner, I fuel my Highlander with 92-octane gasoline purely to save money—I only use it because the manual approves. Saving a few cents per liter on 92-octane adds up to hundreds of dollars annually, yet fuel efficiency shows little difference compared to 95-octane. No abnormal engine noises are noticeable during city driving. Toyota engineers designed it to be compatible with 92-octane, so regular driving isn’t affected. The only caution is to avoid frequently mixing different octane levels—consistency is best. In the long run, saving money is key, and 92-octane is entirely sufficient.
