The usual stations here are Amoco, Conoco, Chevron (my favorite), Citgo, and handful of Sinclairs, and Flying J stations near the freeway.
Flying J did have a thing years ago about a special additive they had. Agua. :rolleyes:
The Contour and even the `80 Ramcharger both run better if I keep the Citgo far, far away from their fuel tanks. Amoco and my parents are in a lawsuit right now, so obviously I don't go there.
