Should the Civic 1.5T Use 92 or 95 Octane Fuel?

[MacIsabelle]

The manufacturer recommends using 92 octane fuel. The Civic model is equipped with an L15B8 engine, a 1.5-liter turbocharged 4-cylinder engine producing 177 horsepower, with a maximum power of 130 kW and a maximum torque of 220 Nm. It features direct fuel injection and an aluminum alloy cylinder head and block. Gasoline Octane Rating: The octane rating is classified based on the octane number, which represents the ratio of the gasoline's anti-knock properties to those of standard gasoline. A higher octane rating indicates stronger anti-knock performance, but it doesn't mean higher is always better. The appropriate gasoline grade should be selected based on the engine's compression ratio. 92 Octane Gasoline: 92 octane gasoline has an octane value of 92 and a heptane value of 8. It is suitable for mid-range vehicles (those with relatively low compression ratios). On December 18, 2013, the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of China jointly issued the fifth-stage national standard for automotive gasoline—"Automotive Gasoline."
