Only a few years ago sunoco never made the list for top tier gas lol.
Only recently they made the list, i suppose they changed their formula.
I have both a sunoco and shell blocks from my house. But back then when they were doing entrance/exit construction to the shell station (my preferred gas), i couldn't go because my car was low and i would have messed up the car just to get gas. So i had to go to sunoco. After ONE fill up of sunoco 93, about 20 miles after the fill up, my check engine light came on. Shortly after that my gas gauge took a crap. I'm talking about it went from full, then it got stuck on 1/4. So i had no idea how much was in the tank from that point foward.
So i bought techron fuel cleaner and dump the bottle. Drove conservatively to get rid of the crappy sunoco gas. About 200 miles later, i put another bottle of techron fuel cleaner and filled up with shell 93 from a different station.
50 miles later the gas gauge fixed itself and check engine light went away. And never had that problem in that car again for another 15 months until i traded it for the C7Z.
Never used sunoco since then.
Shell 93 in every car i own now.

he is incorrect, there are plenty of NA vehicles that knock if the highest octane fuel is not used at the pump. I just didn't feel like calling him out, but when I have seen NA cars ping, and then stop pinging, its a direct contradiction to his statement. He may not have HAD an NA car that NEEDED the higher octane, that i believe. But NO car is going to knock with higher octane and then stop knocking with lower octane.
It makes zero sense. He does not know what he is talking about.

yeah, in the midwest, shell and sunoco are the best. BP and all the random stations are the worst. Everything else is hit or miss. The shell station you say is not good.... ask if they have the shell truck come or if it is some random supplier. I have never heard of shell being bad fuel.
