MMT additive in gas. who sells it?

[blacksaab2007]

Are there any gas stations in the USA using MMT?

Saab 2007 9-3 Owners Manual says:

"Some gasolines that are not reformulated for low emissions may contain an octane enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. Saab does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your authorized Saab dealer for service."

EPA Comments on the Gasoline Additive MMT (methylcyclopentadienyl manganese tricarbonyl)

• MMT is a gasoline octane enhancer produced by the Afton Chemical Corporation (Afton), formerly known as the Ethyl Corporation. MMT is allowed in U.S. gasoline at a level equivalent to 1/32 grams per gallon manganese (gpg Mn).

• In its decision on the use of MMT in the U.S., the Agency determined that MMT, added at 1/32 gpg Mn, will not cause or contribute to regulated emissions failures of vehicles. Some have expressed concerns that the use of MMT may harm on-board diagnostic equipment (OBD) which monitors the performance of emissions control devices in the vehicle. As of this time, the Agency believes the data collected is inconclusive with regard to OBD.

I'd tend to trust the Saab engineers' evaluation.
