 So I wonder, what's the point of putting oil in the window of a service station or a gas station? Do they ever sell all that oil? Is it there for show? There's got to be cheaper ways to show off that, hey, we've got motor oil. I don't know. I think of weird things like that whenever I get a chance. I'm Ron Ananian, The Car Doctor. I'll be back right after this. Don't go away.
