Why can Civic use 92 gasoline?

[SanAlina]

Because the Civic user manual specifies the use of 92 gasoline. Precautions for selecting gasoline grades for Civic: The gasoline grade should be strictly selected according to the recommended grade in the vehicle user manual. Suspension type of Civic: Front MacPherson independent suspension and rear multi-link independent suspension. CIVIC is a legendary model of Honda, born in 1972. Over the past 50 years, it has undergone ten generations of innovation and evolution, winning the recognition and trust of 27,000,000 users worldwide. Since its inception, CIVIC has represented Honda's spirit of continuous challenge and breakthrough, and is the most core soul model of Honda.

I've been driving my Civic for over three years, consistently using 92-octane gasoline, which feels extremely practical because this car was designed with China's fuel quality in mind. The manufacturer calibrated the engine with an intelligent ECU system that automatically adjusts ignition timing and air intake to accommodate lower-octane gasoline and prevent knocking issues. In real-world driving, 92-octane fuel is available everywhere, and each fill-up saves a few yuan compared to 95-octane, adding up to significant savings over time. I often drive long distances, and even the 92-octane fuel from small gas stations along the highway works fine—no need to be picky. During routine maintenance, the mechanic checks the engine and says it's in good condition, with no carbon buildup on the spark plugs. I recommend owners confidently use 92-octane fuel and stick to regular maintenance; it doesn’t affect power or fuel efficiency and is well-suited for daily commuters like us.

As a car enthusiast, I've studied the Civic's engine - why can it run on 92-octane gasoline? The key lies in Honda's i-VTEC technology. Despite the high compression ratio, the ECU is intelligent enough to monitor fuel octane levels in real-time, automatically adjusting valve timing and ignition timing to ensure smooth combustion without causing knocking. This design enhances adaptability. Since 92-octane is the mainstream fuel in many Chinese regions, the Civic runs smoothly while saving money. Compared to other cars requiring 95-octane that may face limitations, this Civic feature is quite impressive. Long-term use of lower-octane fuel won't damage the engine thanks to the ECU's excellent buffering effect - owners just need to avoid substandard fuel. This design also gives the Civic extra points in energy efficiency and environmental protection, maintaining reasonable fuel consumption levels.
