I left Valero in 2004.
EDIT: Valero does not have a refinery in that region, the closest one would be in the bay area near Frisco. So I doubt that gas is made by Valero.
Most likely Shell, Tesoro, BP or Phillips 66.
Up there, as with So Cal, 91 octane is 91 octane.
All ethanol is the same too, and it all sux.
If you can actually get real 91 octane without ethanol that is much better than with.
Ethanol has less btus per volume but artificially increases octane rating. It fools the engine into thinking it has higher octane than it really has.
non-ethanol 91 octane should cost at least 50 cents/gallon more.
But with the federal mandates, it is difficult to actually find road-use gasoline without ethanol.
The problem soon will be, where can I find 10% ethanol instead of 15% ethanol gas?
