In seriousness, you shouldn't worry too much. The ECU will protect the motor by pulling the timing. You'll just be driving a neutered car until you can get that 87 out. I'd maybe do one or two 1/2 tank fillups to boost the octane a little at least and then let that mixed tank eventually run all the way down so that you can refill completely with the good stuff. No big deal though...
