Putting around yes but it will probably "ping" when you open her up.

Don't do it. Technically if you never get into boost 87 would be fine, but trust me you will. Don't be cheap, buy premium.

Boost is as addictive as meth or heroin. Buy the good gas cause you won't be able to stay out of the throttle.

Octane "GOOD"
Detonation "BAD"
If you hear pings its probably too late. Melting piston!
Burn no less than 92 octane IMO!!

Late model computers will be able to compensate for poor fuel quality. and on the same note you will get more miles per gallon running the better stuff. It will usually out weigh the cost....

I can't say about Subarus but I have no problems with running a turbo mopar with 87 octane all the time as long as the proper intercooler is utilized and boost level is modest.
On my 12 second Daytona that was 15 psi in the summer and as high as 21 psi in the winter.
