What grade of gasoline does the Li ONE require?

[VonGenevieve]

It requires 95-octane gasoline. Below is relevant information about the Li ONE: 1. The Li ONE is equipped with an extended-range hybrid system, consisting of a 1.2T engine and a new drive motor; the fuel tank capacity has been increased from 45L to 55L; it comes with Li Auto's self-developed LiOS system and millimeter-wave radar for assisted driving functions. 2. In terms of body layout, the Li ONE has discontinued the 7-seat version, with the third-row space increased by 41mm, and features a newly designed steering wheel. The body comes standard with metallic paint in four colors: black, white, gray, and silver. 3. The dimensions of the Li ONE are 5020/1960/1760mm, with a wheelbase of 2935mm.

I've been driving my Li ONE for almost two years now, and I'm quite experienced when it comes to refueling. The official manual clearly states that 95-octane or higher gasoline must be used, which is related to the 1.2T three-cylinder range extender. Although I mostly use electric power, the engine requires high gasoline anti-knock performance when it starts to generate electricity, and 92-octane fuel can easily cause knocking. Last time, a gas station attendant suggested using 92-octane to save money, but I firmly refused—after all, one engine repair could cost as much as three years' worth of 95-octane fuel. In fact, 95-octane fuel's octane rating is better suited for turbocharged designs, and long-term use can also reduce carbon buildup. My monthly fuel expenses are around 400 yuan, and if I use the hybrid mode on long trips, range anxiety is much less of an issue compared to pure electric vehicles.

After studying the engine parameters of the Li ONE, I found that the fuel grade is closely related to the efficiency of the entire range-extender system. The 1.2T engine has a compression ratio of 9.5:1 and is turbocharged, making 95-octane gasoline just right to meet anti-knock requirements. Once, when I encountered a gas station without 95-octane fuel, I tried 98-octane instead, and the fuel consumption actually decreased by about 0.3 liters. However, using 98-octane long-term is too costly and not cost-effective. Never listen to those who suggest using 92-octane to save money—it might be fine in the short term, but over time, piston ring wear will increase. I also recommend checking the fuel tank cap seal when refueling, as gasoline in hybrid vehicles oxidizes faster than in pure gasoline cars.

Having driven a hybrid car for three years, I have firsthand experience with refueling. The Li ONE must use 95-octane gasoline, primarily because of its 1.2T engine that serves as a generator. During last week's maintenance, the technician mentioned that using the wrong fuel grade can most easily damage the high-pressure fuel pump, with repair costs equivalent to half a year's fuel expenses. I make it a habit to refuel when the fuel gauge shows a quarter left to prevent the fuel pump from overheating. Although 95-octane fuel is slightly more expensive than 92-octane, the combined fuel and electricity cost per kilometer is just over 30 cents, much cheaper than a pure gasoline car. On highways, I usually switch to fuel priority mode, and with a full tank, the car can travel 700 to 800 kilometers.

The fuel octane rating is directly related to engine tuning. The range extender in the Li ONE is designed to operate at higher temperatures than conventional engines, making 92-octane gasoline prone to pre-ignition under such conditions. Based on my winter testing in northern China, cold starts are noticeably smoother with 95-octane fuel. I consistently refuel at Sinopec stations for more stable fuel quality. With a 45-liter fuel tank capacity, I'd advise new owners not to wait for the low-fuel warning - excessively low fuel levels can affect the fuel pump's cooling. Actually, range-extended vehicles require refueling far less frequently than conventional cars - I average just one refuel every two months. The system automatically updates the remaining fuel range display after each refueling.

Unlike refueling conventional gasoline cars, hybrid vehicles require special attention to fuel compatibility. The Li ONE performs best with 95-octane gasoline to maintain optimal range extender system operation, which directly impacts generator output efficiency and battery charging speed. Once I used 92-octane on a long trip and observed a sudden 10% increase in fuel consumption – dealership diagnostics revealed engine knocking caused power reduction. Now I always check fuel labels and strictly avoid anything below 95-octane. The fuel filler is located on the right rear side; remember the charging port cover won't open simultaneously when unlocking. Final reminder: 95-octane formulations vary by region, so prioritize major chain gas stations for more consistent quality.
