That's a screen shot from Waze. It's my favorite nav app. Tells you if there are cops ahead, predicts your route based on history, all that smart shit. Like gas listings in your area.
I sometimes go to citgo. Occasionally lukoil. I see on Waze that exxon was actually cheaper 3 days ago, but that station never seems to be open. There's a sunoco, but it's inconvenient pulling out after. Oh, I also use Coastal in Pennsauken a good bit. They usually are about the same as Wawa. And no credit card premium.
