What grade of gasoline should the Highlander use?
2 Answers
The Highlander can use gasoline with an octane rating of 92 or higher. Currently, China's National IV gasoline grades include three types: 90, 93, and 97. The National V standards include 89, 92, and 95. Gasoline grades are classified by octane rating; the higher the number, the better the anti-knock performance. The appropriate gasoline grade should be selected based on the engine's compression ratio. The Highlander features a spacious body and an innovative, roomy interior, making it one of Toyota's large-sized SUVs. The vehicle's dimensions are 4890 mm in length, 1925 mm in width, and 1715 mm in height, with a wheelbase of 2790 mm. The Highlander is equipped with active headrests that effectively protect the driver's head and neck in the event of a collision. It also features an engine hood and fenders designed to absorb impact energy by denting upon collision with a pedestrian, thereby reducing injuries to pedestrians in such incidents.
As a long-time Highlander owner, I've always used 92-octane gasoline, and the car runs smoothly. The gasoline grade refers to the octane rating, and 92 is sufficient for daily commuting and mountain driving; using a lower grade like 89 may cause engine knocking and damage. It's advisable to check the sticker on the fuel filler door or the user manual, which recommends 92-octane or higher unleaded gasoline. Some people try 95-octane out of curiosity, but it's unnecessary unless you frequently haul heavy loads or drive aggressively. However, never overlook fuel quality—fill up at reliable stations like Sinopec to avoid carbon buildup from poor-quality fuel. In summary, just follow the manufacturer's recommendations for simplicity and safety.
