Yes, an oil temp gauge is in my future plans. Don't know why Subaru decided not to include one?
However, I don't want to use those "racer-boy" gauge pods for the dash or A-pillar....or...maybe I should so I can deflect the "WTF" stares from other wrx/sti owners. :P
But yes, my car is OFF during most of my commute anyways, so engine cooling shouldn't be a big problem
