The answer to the original question is NO the cost will not drop. This is straight from vp fuels mouth:
"The chemicals divisions of the refiners and global oil companies trade chemicals without regard to the price of crude or retail prices at the pump. Many chemicals used in racing fuels here and around the world are also used in other industries and it is that demand that can keep the prices up or drive them even higher. Chemical suppliers decide on the margins and set the prices. Sellers of pump gas trade it as a commodity."
