1 Answers
Changan CS75 is more fuel-efficient with 95 octane gasoline. 92 Octane Gasoline: 92 octane gasoline has an octane rating of 92 and a heptane rating of 8, suitable for mid-range vehicles. 95 Octane Gasoline: 95 octane gasoline consists of 95% isooctane and 5% heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in high-compression engines can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, with a distillation range of 30°C to 220°C. Its main components are C₅–C12 aliphatic hydrocarbons and cycloalkanes, along with a certain amount of aromatic hydrocarbons. Gasoline has a high octane rating.
