Lots of missing the point here.
Yes, the gas is all the same, and various companies do indeed add their additive package.
BUT, it's the additive package that makes the gas "top tier," so the fact the base gas is the same isn't really so relevant.
The exposes, lawsuits, etc., would already have happened if the additives weren't being added as advertised.
Who wants to spend money on some high dollar testing?...My dad was in the Petro Inspection business ( middlemen for seller/buyer to assure the product loaded was the product delivered) for over 40 years and I used to hang out in the lab...not a cheap process I would imagine for verification of blended gasolines.
You just trust the big boys to do the right thing....and have a gut feeling they really are not. And the few stations that offer three blends of fuel when there are only two storage tanks. The pump is blending the reg/premium to give you midgrade....never trusted that to be happening.
