The whole idea of the poster whom I quoted was to give a rough and pragmatic estimate of the relation between gasoline prices and the price of crude oil.

The actual relationship is not arithmetic, but rather a shifting concatenation of refinery charges, taxes, shipping expenses, wages, bargaining, temporary dislocations, a little speculation, international politics, domestic politics, and so forth.

Anyone who imagines that I was stating that you divide 42 into the price of crude oil and get the price of a gallon may have had the fleeting satisfaction of considering me a fool, but that's about it.

Roughly speaking, gasoline at $5.75 a gallon can justify crude at $200, if it is permissible to to return to the main point.

Technically true that one can add H2 in a reduction process, and break long hydrocarbon chains into shorter ones. But that takes energy, and can be done only if enough light volatiles are available to be consumed as an H2 source and as an energy source. If not, the process is not energy efficient, though nevertheless feasible.
