GASOLINE

Gasoline is a complex mixture of  hydrocarbons - paraffins, olefins, naphthenes, and aromatics.  The combination of hydrocarbons and oxygenates determines its physical properties and engine performance characteristics.

As different gasolines contain mainly hydrocarbons, the only significant difference between grades is the octane rating of the fuel.  Octane ratings measure fuel properties:  the ability of the unburnt end gases to spontaneously ignite under the specified test conditions.

The spark ignition internal combustion engine's compression ratio had been inhibited by the unwanted "knock" that could rapidly destroy engines. "Knocking" describes the sound heard from an engine using fuel of too low octane.

Anti-knock index is also known as the Pump Octane.  Unleaded gasoline with an antiknock index of 87, 89, 91 or leaded gasoline with an antiknock index of 88 are typical for the US at sea level.  Lower octane numbers are specified for higher altitudes.  

There are varied Octane Ratings:   

     The Research Octane Number [RON] = typical mild driving, without consistent heavy loads on the engine.

     The  Motor Octane Number [MON] =  severe, sustained high speed and/or high load driving.

     The Road Octane Number [RdON] lies between the MON and RON

GASOLINE TESTING ANALYSIS - NEW
