I have been challenged by a Customs Official to prove that at least 70% of standard motor oil, transmission oil, etc. comes from petroleum. He will be satified if I can supply him a web site or public information site that says this.
I realize this is like proving that my teak desk was once a tree, but he insists that I give him more information.
Has anyone come across a site that can demonstrate this?
I've already given him various references, including " Base oil is the petroleum component of the lubricant. Generally, the base oil comprises eighty percent of the lubricant, with the remainder being additives." from one of the pages here. The funny thing is that I would pay LESS taxes if it was not.
I'll try any links you can suggest.
