Can't believe people still say to "sell your car if you dont want to put the 'right' gas in..." People are trying to save money, even if its just a few dollars, dont be a douche. If you have a GSR, put in premium because you get slightly better fuel economy which in the end is about the same cost as putting in regular.
Put in Regular gas if your car is non-vtec, no reason in paying more.
I do suggest throwing in a can of fuel system cleaner every couple years or so after the winter fuel blend ends around spring time. Ask your fuel attendant when they switch.
