This measures a fuel's resistance to "knocking" or "pinging" during combustion. Higher octane numbers indicate the fuel can withstand more compression before detonating.
Modern gasoline is rarely just "straight-run" from a distillation tower. To meet high demand and performance standards, refineries use several chemical processes: Malserc - GASOLINE
This determines how easily the liquid turns into a gas. High volatility is needed for cold starts, but it must be balanced to prevent "vapor lock" in hot weather. This measures a fuel's resistance to "knocking" or
Gasoline, often referred to as petrol, is a transparent, petroleum-derived liquid used primarily as a fuel in internal combustion engines. It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. Composition and Chemical Nature often referred to as petrol
