I know that this topic has been covered before, but I just can't find it now. Since the day I picked up my car from the dealership, she has been running on premium. Now that I don't got so much money to spend on gas, do you think by reducing to regualr gas I will hurt the car's performance? I know that the manual recommmends bases to run on regular, but since my car is used to the premium, I'm just abit worried that it might not run as well. Should I pump regular or stick out a couple of extra change for the premium?
