i have a 09 ninja 250 and i usually just buy whatever gas is cheapest or the station that happens to be closest to me when i need a fillup.
I heard some people saying that some stations have more sulfur, some have more rust additives, stabilizers, ethanol, etc. Ive asked some friends and some of them only buy shell, some only buy chevron.
What stations do you go to and why? Does it really matter? I thought gas was just gas.
