The only differences are the post-production additives (i.e. Techron, etc) that are designed to burn cleaner. So basically the need to spend "x" for "y" gas is purely marketing

Correct. My original question applied to the additives. Maybe there is so little additives that it makes no difference, but maybe some companies use more and some use less. Maybe the additives lower the octane? I have researched this and googled that and have found no studies or lab analyisis of different brands of fuel.
