Both style coolants are ethylene glycol. It is the additive package that is different. The advantage that the OAT has over SCA is not having to check and adjust SCA levels.
Neither has a cooling advantage. Old coolant will not directly cause cooling issues. However scaling inside the radiator associated with lack of coolant attention, use of water containing minerals, or corrosion due to depletion of anti corrosives can contribute to lack of cooling.
