Maxlife is "T-IV", so is Castrol Syn, PetroCan DuraDrive, so.... All of these would be valid options and not necessarily any less suitable than Mobil Super 3009.
Toyota T-IV and Mobil 3309 are the same thing. The spec'd OEM fluid.
Maxlife is "supported for use" (by Valvoline) in 3309/T-IV applications but does not have official manufacturer approval.
