What type of gasoline does the Highlander use?
2 Answers
The Highlander uses 95-octane gasoline. The Highlander is equipped with a 2.0T turbocharged engine, which is suitable for 95-octane gasoline. 95-octane gasoline consists of 95% isooctane and 3% n-heptane. When the engine has a high compression ratio, high-octane gasoline should be used. If low-octane gasoline is used in a high-compression engine, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving performance. The Highlander is a large SUV under the Toyota brand, with body dimensions of 4890mm in length, 1925mm in width, and 1715mm in height, and a wheelbase of 2790mm. It is a 5-door, 7-seat SUV.
I've always driven a Highlander and use regular 87-octane unleaded gasoline, just as Toyota recommends. The engine is well-designed and perfectly adequate for daily driving, whether it's shuttling kids around the city or cruising on the highway. The new car manual clearly states that 87 octane is the minimum requirement—don't fall for gas station attendants pushing premium fuel; it's a waste of money. I once tried 91-octane to see if it improved acceleration, but the difference was barely noticeable, just a pointless expense. With gas prices high now, sticking with 87-octane saves a lot—a few dollars per fill-up adds up over time. Maintenance is straightforward: avoid mixing lower-octane fuel to protect the engine, but occasional mistakes won’t cause major harm. In short, following the manufacturer’s guidance is the easiest way to ensure long-term reliability and durability. Plus, my Highlander’s fuel efficiency stays steady around 18 mpg, so keeping it simple with fuel choices is the smarter move.
