Does continuously using 95-octane fuel affect the 10th-generation Accord?

Continuously using 95-octane fuel does not affect the 10th-generation Accord. Powertrain specifications of the 10th-generation Accord: The Accord is a midsize sedan under Honda. The tenth-generation model is equipped with three engines: a low-power version 1.5-liter turbocharged engine, a high-power version 1.5-liter turbocharged engine, and a 2.0-liter naturally aspirated engine. Configuration details: The 10th-generation Accord features a MacPherson strut front suspension and a multi-link independent rear suspension. The multi-link independent suspension enhances wheel-to-ground performance, which consequently improves the vehicle's handling.

I often ponder these things when driving, and there's really no big issue with using 95-octane fuel in the 10th-gen Accord. The manual states that 92-octane or higher is acceptable, with 92 being the minimum requirement. In fact, 95-octane's higher octane rating can help reduce engine knocking. However, the Accord's 1.5T engine has a compression ratio of only 10.3:1, so it doesn't actually require such high-octane fuel. Using 95 long-term is just wasting money—currently, 95 costs about 0.7-0.8 yuan more per liter than 92. If you drive 20,000 km a year, you'd spend over 2,000 yuan more on fuel. It's even less necessary for the hybrid version, as the system automatically adjusts power output. A friend of mine has been using 92-octane in his Accord for five years, and the engine is still in great condition.

I've worked on quite a few Honda vehicles, and the Accord is a pretty worry-free car. While 95-octane gasoline does have slightly better cleanliness than 92-octane, resulting in less carbon buildup, Honda engines are actually designed for 92-octane fuel. Manufacturer tests have confirmed that 92-octane fully meets performance requirements. Insisting on using 95-octane provides more psychological comfort than actual benefits. What's more important is to avoid mixing 92 and 95 octane fuels - fluctuating octane levels in your tank might actually reduce combustion efficiency. Currently, 92-octane is the most readily available fuel grade, even in tourist areas where fuel shortages are unlikely. For genuine engine maintenance, regular use of fuel system cleaner is more practical than upgrading fuel octane.
