My Good Chevron Fuel Experience

[LSchicago]

There is ZERO chance that the difference between brands of top tier gasoline of the same octane is even 1 mpg.

Almost as amazing as all those "Theo/Turbo" ESS threads.......

It really is laughable that people will actually come in here and argue that the change in brand from one top-tier fuel to another can get you an almost 20% improvement in MPG. If that were the case, the brand would be SCREAMING it from the rooftops, car manufacturers and big .gov would mandate that you use it.
"feels peppier" isn't valid either. Show me A/B runs on a dyno. They don't exist, I wonder why?
Critical thinking just isn't common.
