Oh, it will. According to the speaker at a seminar on gasoline at Oshkosh a few years
ago, there is currently only one plant making tetraethyl lead. It's in Britain. They
have announced that they will be closing down within eight years due to a decreasing
market and the age of their equipment. I would expect that, if it is uneconomical for
that company to upgrade their equipment, it will not be economical for any other firm
to build a new plant and enter the market. Maybe the Chinese could, however.
