If they remain separate at all time you could even try a multi-component approach (cheaper).

Yes it is, with Radiation models even if you are interested in heat exchange I believe.

Yes, this is possible. One problem you might have with the multi-component flow approach is that the flow of Oil will likely be laminar and the flow of air turbulent. You can't do this with multicomponent flow modelling. You can probably try this using the multi-fluid (phase) model instead, but I am skeptical about whether you will be successful.
