Hi Steve, & greetings from the Critique Club.
Well, I don't hail from your parts, so I am really just guessing that the conspiracy is that a $65 pack of oil ain't really worth that much. It's a basic 10W-30 oil, so for 65 bucks that pack size had better be a few gallons! (and I'm guessing again ... it's not). Anyway, oil company conspiracies always appeal, so your idea is OK. The photograph is pretty good; nice off-centre composition, sharp focus and good lighting all work well. A tiny bit of light bounced back onto the label might have helped me read the pack size, so I'd be able to assess the extent of the rip-off that is the point of your image. There's not much to say beyond that; it's a good if parochial idea (sort of like an "in" joke), and a respectable photograph. Not exciting, but not dull either.
Maybe just a small clockwise rotation on this image to bring it the left edge of the bottle verticle and align it to the left edge of the frame. Since it was advanced editing, and depending on your editing program, you might also have burned the light around the base of the bottle of really isolate it.
I like the title - made me nod my head and smile. I like the shot. I know the bottle is yellow, but here it has a bit of green tinge (at least on my monitor). Very clever take on the challenge though and I like the composition.
