MMT additive in gas -- not recommended by Saab.
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."
