Should the Jeep Cherokee use 92 or 95 octane gasoline?

Jeep Cherokee fuel requirements vary by specific model: 1. The 2.0L and 2.4L versions use 92 octane gasoline; 2. The 2.0T version uses 95 octane gasoline. Taking the 2021 Jeep Cherokee 4WD 80th Anniversary Edition as an example, it is a mid-size 5-door, 5-seat SUV with body dimensions of 4669mm in length, 1865mm in width, 1691mm in height, and a wheelbase of 2707mm. The 2021 Jeep Cherokee 4WD 80th Anniversary Edition is equipped with a 2.0T turbocharged engine and a 9-speed automatic transmission, delivering a maximum power of 195 kW and a maximum torque of 400 Nm.
I drive the Jeep Cherokee 2.4L model, and the manual recommends using 95 octane gasoline. While 92 octane can work in a pinch, I must specifically warn you: when climbing slopes, the engine noise is noticeably quieter with 95 octane. The gas station attendant told me the Cherokee's engine has a compression ratio of 9.2:1, and using 95 octane helps reduce knocking. Especially during summer with AC on and full load, higher-octane fuel provides more stable power output. I tried using 92 octane for three consecutive months and found the fuel consumption was about 0.8L higher compared to 95 octane - the savings turned out negligible. For long-term vehicle use, I genuinely advise against compromising engine health to save a few cents.
Last week, I helped my neighbor uncle check his 2017 Jeep Cherokee. The sticker inside the fuel tank cap clearly stated 'Please use 95 octane or higher unleaded gasoline.' The old man had been using 92 octane all along and mentioned that the cold starts were a bit shaky recently. Practical tests showed that 92 octane isn't unusable, but for turbocharged models, the ECU automatically limits the ignition advance angle during rapid acceleration when using lower-grade fuel. A special reminder for northern car owners: using 95 octane in winter makes cold starts smoother. Maintenance for the Cherokee isn't cheap, and if carbon buildup issues arise from saving on fuel costs, the money spent on cleaning the fuel system could cover two years' worth of 95 octane fuel.
