Well, First of let me say Welcome (A little late but better than never.. lol )
I Think that in order for a Turbo-Charged vehicles to run smooth and with out any Detonation (Especially with our crappy 91 Octane) You would want to have super unleaded .. because they run hotter faster and well with that in mind comes the Full Synthetic oils which to me run cooler and tend NOT to break down so easily.. But then I am not an expert on cars .. so I leave this question up to the Pros on this forum .. lol ...
