It is accurate Bill. By default if you add something to gas, then there is less gas per gallon dispensed. Every additive out there I know of has fewer btu than gasoline, thus, every additive (ethanol, tetraethyl lead, detergents, stabilizers) reduce the btu you get from that gallon.

Now I will agree the additive(s) only change the btu content a few % at most.

 

Other than alcohol, which is added as a per centage... how much of an additive is added per ~8,000 gallons of a truck load?

As to the btu content change... its an insignificant amount. The base gasoline has the same btu content regarless of octane.

Give me a break. This is an insignificant point.

 

Bill-

The point is NOT ALL gasoline is created equal.

Pick a brand. "Shell".
Pick an ethanol state. "Illinois".

10% of the volume Shell sells in that state needs to be ethanol.
That is not the same as 10% of every gallon sold is ethanol.
It is a legality, and a technicality.
Just like to move Ford's fleet average to 25 MPG, for every Hybrid they sell, they can sell an F-350. One offsets the other.

States that sell lots of E85, can sell regular gas at the pump, and still average 10%. I see it every day. ( well, at least every week )
