Should Roewe use 92 or 95 octane gasoline?

[LaOwen]

Roewe recommends using gasoline with an octane rating of 92 or above, so generally using 92 octane gasoline is sufficient. Below is an extended introduction: Recommended octane rating and above: Use automotive gasoline that complies with national mandatory standards and the recommended octane rating. Using lower octane fuel may cause severe damage to the engine and catalytic converter, reduce engine power and torque, and increase fuel consumption. If lower octane gasoline is used, engine knocking noises may be heard, so it is advised to switch to the recommended octane rating or higher as soon as possible. Use gasoline suitable for the compression ratio: For vehicles with high compression ratios, using lower octane fuel not only damages the vehicle but also increases fuel consumption. Conversely, using higher octane gasoline in vehicles with lower compression ratios not only wastes money but also leads to slower ignition, prolonged combustion time, reduced power, and even damage to the exhaust manifold. Only by using gasoline that matches the vehicle's compression ratio can engine power be improved, driving range increased, and fuel consumption reduced.
