tert-Amyl methyl ether (TAME) is an ether used as a fuel oxygenate. It has an ethereous odor.[1] Unlike most ethers, it does not form peroxides on storage.


TAME is mostly used as an oxygenate to gasoline. It is added for three reasons: to increase octane enhancement, to replace banned tetraethyl lead, and to raise the oxygen content in gasoline. It is known that TAME in fuel reduces exhaust emissions of some volatile organic compounds.[1]


When exposed to lab rats at 4000 ppm only 25% survived, the rest had died of central nervous system depression.[3]
