BP 93 octane. I think BP and Amoco have kinda combined or something. The signs at the gas stations say "BP Welcomes Amoco Fuels"
I always used Amoco premium, and from experience in changing a gas tank can say that their premium is/was crystal clear, it looked like clean water. BP stands for British Petroleum, they bought Amoco some time ago and use BP because they don’t want Americans to know where exactly their money is going. I did notice that after being absorbed, Amoco gas started using Ethanol. With all this talk, I’ll be looking for a Chevron station in the future.
Bmw 325i 7803 made a good point:
Well just watch out for those NO NAME gas stations which dont clean their tanks or "waterdown" their gas, when it comes to name brands then yes you can chase the penny.
Also watch out for the tanker trucks, from my understanding when they refill the station all of the impurities that settle at the bottom of the tank are stirred around and can get into your tank.
