I cant work out why we have 3 different grades of fuel for cars. 91, 95 & 98. Why cant they just standardise on 98 and take the advantage of economies of scale.
I like your idea, but it just does not work like that.
I want to breed cattle that give 100% eye fillet steak, but instead you get all the other cuts in larger volume. Refining is much the same. Even avgas, the stuff from BP in WA is not the same as the Geelong stuff from what was Shell. The BP has way more lead because of a lower grade alkalyte.
As for all JetA burners……don't hold your breath.
