The owners manual should reference that but anecdoatally HECK YEAH. Octane needs are determined by the compression ration and the timing curve of the specific vehicle. Using higher octane fuel than is required by the engine is not harmful to the engine but can be costly if it is not really needed. Using fuel with a lower than required octane rating can be harmful to the engine.
