Should the Toyota Camry use 92 or 95 octane gasoline?

Toyota Camry uses 92 octane gasoline. The gasoline grade is divided according to the octane number, which is the ratio of gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance, but higher grades are not necessarily better. The appropriate gasoline grade should be selected based on the engine's compression ratio. The Toyota Camry is a mid-size 4-door 5-seater sedan with body dimensions of 4885mm in length, 1840mm in width, and 1455mm in height, and a wheelbase of 2825mm. It is equipped with a 2.0L naturally aspirated engine and a CVT continuously variable transmission, delivering a maximum power of 131 kW and a maximum torque of 210 Nm.

My Camry has been running for over three years, always using 92-octane fuel. The manual clearly states that 92-octane gasoline is acceptable, as Toyota's 2.0L and 2.5L engines are designed with compression ratios suited for regular gasoline. Once during a long trip, I temporarily filled up with 95-octane, and honestly didn't notice any change in power—just higher fuel costs. At the gas station, I see others opting for higher octane, but I don't think it's necessary. As long as you go to a reputable gas station, 92-octane is perfectly adequate. Carbon buildup mainly depends on driving habits and maintenance. The money saved is better spent on frequent air filter replacements.

Tested two Camrys, one consistently using 92-octane and the other 95-octane. Under the same road conditions, the difference in fuel consumption per 100 kilometers was less than 0.3 liters, but 95-octane costs nearly 1 yuan more per liter, equating to about 0.3 yuan more per kilometer. The key point is that Toyota engineers have calibrated the engine to adapt to 92-octane fuel, with the ECU automatically adjusting the ignition timing. Instead, be cautious not to use gasoline with excessive ethanol content, especially in northern regions during winter, as it can genuinely harm the engine. For engine protection, it's better to regularly use fuel additives to clean the fuel system.

Let's do the math: The Camry has a 60-liter fuel tank, and using 92-octane instead of 95-octane saves you 48 yuan per tank. Based on 20,000 kilometers per year and 8 liters per 100 kilometers, you can save 1,536 yuan annually. Isn't it better to spend that money on full synthetic oil? Some claim higher-octane fuel lasts longer, but gasoline energy density is nearly identical. Our fleet's real-world test showed less than a 20-kilometer difference in range over 300 kilometers of continuous highway driving between the two fuel types. If you really want to improve combustion efficiency, regular throttle body cleaning is more effective.

I've talked to an experienced auto repair technician about this, and he said Toyota's naturally aspirated engines with their piston crown design are built to run on regular fuel. I've seen a Camry with 200,000 kilometers that's been using 92 octane, and when the engine was opened up, it had much less carbon buildup compared to some German cars. The key isn't the octane rating but the quality of the gasoline. High-octane fuel from small gas stations might contain more gum deposits and could be worse than the 92 octane from the two major oil companies. Unless you frequently drive aggressively at 4,000-5,000 RPM, using 95 octane is purely for psychological comfort. Regularly driving on highways to clean out carbon deposits is more effective than obsessing over octane ratings.
