Should the Captiva use 92 or 95 octane gasoline?

The Chevrolet Captiva can use 92 octane gasoline. Here is the relevant information: Captiva: The Chevrolet Captiva is a vehicle launched by Chevrolet. Model: Compared to the current Captiva, the new model features LED taillights, along with subtle adjustments to the rear bumper and exhaust pipes. According to official sources, the new Captiva also has upgrades in its interior and is equipped with a keyless entry system. The interior is simple and unpretentious, with a bold and masculine style, rich in luxury features, giving it a significant advantage among its peers; the dashboard layout is straightforward, the air conditioning performs well, and the overall ride comfort is good; however, the sound system is average.
Over the years driving my Captiva, I've mostly used 92-octane fuel. The manufacturer's manual clearly states that 92-octane or higher is acceptable, and this is also indicated inside the fuel filler cap. The car comes with a naturally aspirated engine that doesn't have an exceptionally high compression ratio, so 92-octane is perfectly adequate and saves money. Once during a long road trip, I encountered a remote gas station that only had 95-octane. Filling up with it didn't make any noticeable difference in power, just hurt my wallet a bit more. While 95-octane has better anti-knock properties, our old buddy here really doesn't need it unless you frequently floor the accelerator uphill or the car is particularly old with some carbon buildup. Calculated over time, sticking with 92-octane saves a significant amount of money—enough for an extra maintenance service.
After studying the Captiva's engine data, this generation of LTG engine has a compression ratio of 10.5:1, which is significantly lower than many newly released turbocharged vehicles. The octane rating of 92 gasoline fully meets the anti-knock requirements, unless the powertrain has been modified. I remember conducting a test on the same route using both 92 and 95 octane fuel, and the difference in fuel consumption was only about 0.3 liters per 100 kilometers. However, the price difference was nearly 0.8 yuan, and the actual calculation showed that using 92 octane fuel saved 5 cents per kilometer. With fuel prices so high now, there's really no need to spend extra on 95 octane. The money saved could be better spent on a good set of windshield wipers.
