More likely there was just no call for a petrol station or tanker to show up in Runaways. I mean the main reason movies & TV shows use fake companies like this is so they don't have to bother getting clearance using a actual brand name. In the case of Marvel it also just to happens to be a comic book reference at the same time.Roxxon plays very heavily into Cloak and Dagger, maybe they didn't want to use them in both franchises.
