Where I drive Citgo diesel fuel foams very bad and I have to watch for foam coming out the filler so I can shut it off soon enough. If I were to wait for the nozzle to shut it off, it would be on the ground. I have no problem with Meijer, Flying J, Pilot, Shell, Mobile, Thorton's, BP, or Speedway.
So for me, CITGO is off my list. I have not tried Sonoco.
