Why Do Turbocharged Cars Require 95 Octane Gasoline?

[StDerek]

Turbocharged cars require 95 octane gasoline because higher-octane gasoline offers better combustion stability and knock resistance, preventing detonation due to increased cylinder pressure. A turbocharged engine is one equipped with a turbocharger, which is essentially an air compressor that increases air intake by compressing air. Characteristics of gasoline include: 1. Volatility: It rapidly vaporizes in the engine cylinder and mixes with air to form a uniform combustible mixture. 2. Stability: This refers to its ability to resist oxidation under normal temperature and liquid-phase conditions. 3. Knock Resistance: This is the gasoline's ability to resist knocking under various operating conditions. 4. Corrosiveness: Sulfur compounds in gasoline can cause corrosion to materials.
