Can the Nissan Sunny use 95-octane gasoline?
2 Answers
Nissan Sunny cannot use 95-octane gasoline. The manufacturer requires this model to use 93-octane gasoline. Gasoline grades: Currently, gasoline grades available in the market include 90, 93, and 97. These numbers represent the octane rating of gasoline, indicating its anti-knock performance, and have no relation to the cleanliness of the gasoline. The claim that "higher-grade gasoline is cleaner" is purely misleading. Refueling according to requirements: Refueling based on the engine's compression ratio or the requirements specified in the car's manual is more scientific and economical, and can fully utilize the engine's efficiency. Compression ratio: During the design phase of a car engine, the gasoline grade to be used is determined based on the compression ratio. The compression ratio is a very important structural parameter of the engine, representing the ratio of the gas volume when the piston is at the bottom dead center at the start of compression to the gas volume when the piston is at the top dead center at the end of compression.
I recently bought a Nissan Sunny and was curious if I could use 95-octane gasoline. I checked the user manual, which recommends 92-octane fuel but states that using higher-octane fuel is also fine and won’t damage the engine. 95-octane fuel might burn cleaner and reduce carbon buildup. I tried it once and felt the car started more smoothly, and acceleration was smoother, but in city driving, the difference wasn’t noticeable. As for fuel consumption, I didn’t notice much change—I still follow the recommendation on the fuel cap. The key is regular maintenance; you can’t just rely on premium fuel to save money. Although 95-octane is more expensive, it’s okay to use occasionally for the car’s condition. In summary, the manual says it’s fine, so you can use it if you want—no need to worry about knocking—but there’s no need to use it daily. Standard fuel is sufficient, cost-effective, and practical.
