day as well.
I am sure there are a TON of na's out there full of 87. Of course they probably don't drive them like the NA guys on here do.
I have never heard what octane rating consitutes premium anyway. I know 93 is the top we can get in MO, but some states it is 91. Have not seen lower than that if i recall.
