Octane rating is the rating given to combustable fuels that shows that fuels resistance to detonation. detonation is also known as knocks. knocks are VERY bad for an engine and efficiencies aswell, because it is simply the fuel going off before it is supposed to (premature combustion). the higher the octane rating (the pump's octane is an average of two different methods of obtaining the octane number) the more resistant the fuel will be to knocking. higher octane fuels WILL NOT increase your fuel economy, if you have observed that such is not the case, then there is another factor that needs to be considered when comparing the high and low octane fuels in your driving regemine.

How do you convert Octane ratings into PSI or is it not that simple?

It's not that simple. To keep things simple, though - use fuel with the octane rating that your car's instruction manual says you should.


What is the element octane?

Octane is a hydrocarbon compound with the chemical formula C8H18. It is a component of gasoline and is used as a reference standard to measure the performance of fuels in internal combustion engines. Higher octane ratings indicate greater resistance to engine knocking or pinging.


What is the measure of the antiknock properties in a fuel?

The measure of antiknock properties in a fuel is typically expressed using the octane rating system. Higher octane ratings indicate better antiknock properties, meaning the fuel is less likely to cause knocking or pre-ignition in an engine.


Is 87 octane gas as good as 89 or 91 octane gas?

Probably, yes. Gasoline comes with different octane ratings because some engines require a higher octane to prevent pre-ignition ("pinging" under acceleration or on hills). Check your owner's manual. Also, you can experiment with lower-octane (and therefore less expensive) gasoline. If you do not experience pinging with 87 octane gas, then that is all you need.(Technically, a higher-octane gas burns slower than lesser-octane gas, but that is beyond the scope of this question.)


What is the purpose of Octane ratings?

Octane is used to reduce pre detonation in high compression engines. The rating tells the driver which fuel to purchase and use in their vehicle as recommended by the manufacture of the vehicle.
