I exaggerated by saying “most”. But I don’t think that graphic is truly representative, a little oversimplified. Where is the cost of ethanol figured in? The cost of the penalties the refiners pay the feds for not using the mandated additives that curiously don’t exist?
The cost the dozens of mandated regional and seasonal blends? Is that part of the 12%? I don’t know.
Although it’s not showing in the retail cost, how about the price each of us *working taxpayers* antes up for the subsidies of the biofuels? Higher food costs? The snowballing costs of this whole biofuels hoax permeates our whole economy to varying degrees.
It is definitely simplified. For starters, each of those other categories, especially the crude oil, contains a significant amount of taxes. It is more of the price per gallon as it moves through the following stages:
Before refinery
After refinery
leaving the wholesale loading rack.
The taxes only are the taxes added onto finished gasoline.
I believe most of the ethanol and specific recipes are done at the blenders downstream of the refinery, but at some refineries, it is done on site. Many refineries just produce gasoline blending products, not finished motor gasoline.
