I wonder if something is amiss with my wagon? 35K miles, 30K done by local suby buddy who works for a suby service dept.
What does 93 octane do for your car that 89 or 91 wouldn't? There's no way your stock tune non-turbo car NEEDS 93 octane to avoid detonation, unless there is something wrong with your car.
