What grade of fuel does the Highlander use?

[McCecilia]

The Highlander uses 95-octane fuel. Gasoline is a volatile and flammable hydrocarbon mixture liquid obtained through distillation, cracking, or pyrolysis of petroleum, used as fuel. Different octane ratings represent varying levels of fuel anti-knock performance, with higher octane numbers indicating better anti-knock properties. The Highlander has dimensions of 4890mm in length, 1925mm in width, and 1715mm in height, with a wheelbase of 2790mm. It features a MacPherson strut independent front suspension and an E-type multi-link independent rear suspension. The vehicle is equipped with a 2.0L inline 4-cylinder turbocharged engine, delivering a maximum power of 165kW and a maximum torque of 350Nm, paired with a 6-speed automatic transmission.

I've been driving the Highlander for almost three years now, and this SUV is quite accommodating when it comes to fuel consumption. The manufacturer recommends using either 92 or 95 octane gasoline. The manual states that using 92 octane is completely fine and more cost-effective. Like me, using 92 octane over the past few years, the fuel consumption is about 10 liters per 100 kilometers on city roads, and it can drop to 8 liters on highways. 95 octane is more expensive, but the engine responds more sensitively during acceleration, making it suitable for mountain climbing or when fully loaded. Never skimp and use 90 octane fuel—short-term use might cause engine knocking and noise, and long-term use can damage performance. Before refueling, I always make it a habit to check the fuel quality and choose reputable gas stations like Sinopec, which have fewer impurities for peace of mind. Regular maintenance of spark plugs and cleaning the fuel system can also improve fuel efficiency. In short, the Toyota Highlander is quite durable, and it's fine to use either 92 or 95 octane—just choose according to your needs.

Our family primarily drives a Highlander, which is our go-to vehicle for family trips. The manufacturer recommends using either 92 or 95 octane gasoline. Using 92 octane is more economical, saving a few cents per liter compared to 95 octane, which adds up to significant monthly savings. My actual fuel consumption in the city is around 11L/100km. While 95 octane is slightly more expensive, it provides more stable power output on highways or when using air conditioning, making rides safer for kids and elderly passengers. Remember to never use lower-octane fuel like 89 octane to avoid potential engine issues and hazards. I always double-check that the gas station's display shows 92 or 95 octane when refueling, and I pair this with regular oil changes and air filter replacements to extend my car's lifespan. Choosing reputable, large-brand gas stations helps prevent impurities. The Highlander's large fuel tank allows for long distances on a single fill-up, making it incredibly convenient and ideal for families.

From a technical perspective, the difference in octane ratings: The Highlander can use either 92 or 95 octane gasoline due to its engine's strong adaptability. 92 octane has an octane rating of 92 with average anti-knock performance and a lower price; 95 octane reaches 95, making it more suitable for high-pressure environments to enhance performance. Modern vehicles are equipped with knock sensors that can automatically adjust, such as the Highlander using 92 octane to avoid carbon buildup issues. However, in high-altitude areas, 95 octane can be chosen to reduce the risk of knocking. Long-term use of lower-grade fuel may wear piston rings, so it is recommended to follow the manual and start with 92 octane to ensure reliability. Using the wrong octane rating has minimal short-term impact, but timely handling can make maintenance costs negligible. Maintaining the fuel system is crucial, requiring regular inspections.
