What burns faster premium or pump gas?

Premium is a "pump gas". "Pump gas" is term used for any grade gas found at any given gas station such as regular, mid grade, and premium. It doesn't burn faster it gives a more complete burn which eliminates a significant amount of the carbon which you get when you burn a lower grade gas.

I must disagree with my learned expert. Premium does not burn faster nor does it give a cleaner burn. In fact it burns slower. The only difference in Premium and Regular is the octane level. A higher octane provides no benefit whatsoever in an engine designed to run on regular. No more power, no better mileage, nothing. In fact if used in an engine designed to run Regular you may suffer harder starting.
