Sounds like you got "trucked" out of your oil
Sorry to hear it, sorry it happened to you. Seems like with this economy, some people have just thrown their ethics to the wolves.
George, try one other thing. Ask a store manager at BP to see if anyone "returned" the same amount of oil and brand you had stolen. Believe it or not, some folks will steal something, and then walk into a store and try to return it to get either fast cash at full retail, or store credit at full retail amount.
Hope the cops nab the guy.
Last thought, depending on deductible, some car insurance compainies wave deductible for thefts rom vehciles, some don't.
