Should the Accord use 92 or 95 octane fuel?
1 Answers
The Accord uses 92 octane fuel. The octane rating represents the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane number, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline grade should be selected based on the engine's compression ratio. Standard gasoline consists of isooctane and n-heptane. Isooctane has good anti-knock properties, with its octane value set at 100, while n-heptane has poor anti-knock properties and is prone to knocking in gasoline engines, with its octane value set at 0. If the gasoline is labeled as 92 octane, it means the gasoline contains 92% isooctane. The new Accord is equipped with three types of 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. The model equipped with the 2.0-liter naturally aspirated engine is a hybrid version.
