I'm just curious what people think about the additives of these two major gas companies. Is one better than the other in terms of MPG/efficiency and performance? Or is there no difference between them?
If either of them made any noticeable difference in most vehicles, it wouldn't be sold in bottles, it would be included in every gallon of gasoline refined in the country. The truth is, most of the time they're a complete waste of money, although occasionally they may only be a partial waste of money.

Interesting question / poll, Volxen . . .
For most all of my "driving" life I always believed the old saying . . . "Gasolines are all the same."
Then back in the late 90s I adopted a 1986 Jeep CJ-7 that turned out to be a big ole pain in the butt to start and keep running, especially when cold. A few very qualified mechanics tried all of the known and some of the not so known tricks with no improvement whatsoever. I had all but surrendered when an old car club buddy / enthusiast asked me what gas I was using. When I said mostly Costco Gas he suggested trying another brand and suggested Shell V-Power Premium.
Believe it or not, after the first tank the Jeep was showing a huge improvement. Now, 15 plus years and never anything but Shell V-Power later, the problem has never reappeared.
I often wonder if it's possible the old Jeep is able to read the pumps.

The difference was likely because you switched octane ratings, from regular (87) to premium (93).
Good article. Pretty much sync's with everything I've read and been told by fuel haulers.
My advice to people is to ignore brands, and just buy at a gas station that has lots of traffic (high turnover = fresh gas) and that looks decently maintained. Hopefully they apply the same mentality to their tanks and filters.
My in-laws hate Citgo gas with a passion. Oddly enough, it's not political. They just think it's junk gas. Conversely, they think BP is the best gas ever. I keep telling them that we have a Citgo tank farm in our city, and that 90% of the gas that is sold within the area comes from that Citgo tank farm (per a recent news article in the paper). So that BP gas that they are buying and claiming is so much better is actually Citgo gas. They just stare at me blankly, and repeat how crappy Citgo gas is. I've learned to just move on....
Filling a tanker truck at the loading rack is like filling a cup at the soda fountain. The bulk of the liquid is RBOB (carbonated water), with a little bit of additive (syrup) mixed in. The additive (syrup) is what brands the product.
I've hauled many loads of Exxon-branded gasoline out of a Valero refinery.
Where I live, there are no branded gas stations that purport to have detergents.
I'm going to start adding a bottle of techron periodically just as a precaution.
All gasoline, whether branded or not, contains detergent additives, referred to as DCAs (deposit control additive). These are mandated by the Clean Air Act.
