I was washing my 01 GTP today and when I opened the gas cover, I noticed a sticker that says "PREMIUM UNLEADED FUEL ONLY"
...Im like

! Nooo! Premium is $4.50!
I have been putting reg in there since the day I got the car. No problem that I can notice.
So whats the deal with premium only? Is it harmfull to put regular in there? Please enlighten me about this whole premium only deal.
Thanks!
