What grade of gasoline does the Lexus UX use?

[McKathryn]

Lexus UX uses 92-octane gasoline. 92-octane gasoline is composed of 92% isooctane and 8% n-heptane. Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled or cracked from petroleum, used as fuel, and appears as a transparent liquid. Taking the 2020 Lexus UX as an example, its front suspension is a MacPherson independent suspension, the rear suspension is a multi-link independent suspension, equipped with a 2.0L naturally aspirated engine, with a maximum horsepower of 173ps, maximum torque of 207Nm, and maximum power of 127kW.

I've been driving a Lexus UX, and the manual clearly recommends using 95-octane or higher gasoline because it has a high-compression engine that requires high-octane fuel to prevent knocking and power loss. Using 92-octane might save some money in the short term, but it will lead to carbon buildup, engine damage, and even shorten the engine's lifespan over time. I've tried 92-octane a few times, and the throttle response noticeably slowed down, while fuel consumption increased—repairs ended up being more expensive. Always check the fuel pump for the 95 or 98 labels when refueling, and choose reputable gas stations to ensure quality. Fuel octane standards vary by region, so sticking with 95-octane is the safest choice in China. Checking fuel levels before long trips can help avoid trouble.

I've been driving a Lexus UX for over a year and always use 95-octane gasoline as mandated by the manufacturer to protect precision components. The hybrid system design requires stable combustion - 92-octane fuel may cause engine knocking or sensor false alarms, increasing failure risks. Daily urban driving feels smoother with more responsive acceleration. Fuel-saving techniques involve smooth driving while avoiding sudden braking/acceleration, but wrong octane selection negates these benefits. Though 95-octane is slightly more expensive during price fluctuations, it's worthwhile. Regular maintenance checks on fuel systems maintain optimal performance.
