Can a car designed for 92 gasoline use 95 gasoline?
1 Answers
It is possible for a car designed for 92 gasoline to use 95 gasoline, but it is not recommended. It is best to follow the fuel grade specified by the vehicle. Below is a detailed explanation of 92 and 95 gasoline: 1. 92 gasoline has an octane rating of 92 and is suitable for mid-range cars (with lower compression ratios). 95 gasoline has an octane rating of no less than 95 and is designed for high-compression engines. Using low-grade gasoline in a high-compression engine can cause a sharp rise in cylinder temperature, incomplete combustion, severe engine vibration, reduced power output, damage to engine components, increased fuel consumption, and poor driving performance. Conversely, using high-grade gasoline in a low-compression engine can result in incomplete combustion, which may harm the engine. 2. The proportions of catalytic gasoline, reformate gasoline, and anti-knock agents in gasoline also vary. There is no difference in quality or cleanliness between the two grades; they are simply suited for engines with different compression ratios. If the car manual states that 92 gasoline or higher is required, either grade can be used. Using higher-grade gasoline in a car designed for lower-grade fuel can improve knock resistance, reduce engine vibration, and make the engine run smoother. However, it is still advisable to follow the manufacturer's recommended fuel grade. 3. If the car manual specifies a minimum requirement of 95 gasoline, then 95 or higher must be used. Using lower-grade gasoline can have negative effects on the car. If the octane rating of the gasoline used is lower than the required rating, it may cause knocking, which can damage the engine.
