Ok maybe you know or maybe you don't but all gas is the same besides the octane ratings. I work at a gas station and my boss owns a BP and a SUNOCO (they all get gas from the same people i sign the papers and know the drivers its all the same). Same guy that delivers my gas delivers GULF and CUMBERLAND FARMS gas. And i also see the same trucks delivering SHELL and other fuel stations. You can put 93 octane in a GP but all it will do is keep it cleaner because its burning cleaner and at a higher temp.
I usually use- 87
But when i go to eat civics in the GP i use- 93![]()
