ive been using 94 for a while now, (maybe 4 months or so) and i noticed a huge difference from the 89 octane i would use from other gas stations, (mainly esso) but after reading this i might just start using shell

p.s. is switching gas stations frequently bad for a motor? i usually stick to sunoco, but ive heard people talking about it so im just curious?
