TBH I can't really tell a difference between fuels I use. I pretty much rotate between QuikTrip, Valero, and Phillips 66, depending on whether my loyalty points for QT are valid for a discount as well as what's convenient for me on my drive. The only time I have noticed anything different was when I used some ethanol-free gas from QT. It's kinda weird - it feels more responsive around town to me, maybe... could be placebo effect, but I know pure gasoline has a higher level of energy concentration than E10.

Try different brand and compare them on dyno. Not even dyno test. Can't tell the difference when you fill up with Shell premium vs. Costco premium? My car just likes
Shell premium. Another example, I use Stihl premixed gas for my chainsaws(Stihl, Makita, an old Poulan) All starts with 3, 4 pulls regarless weather condition, no trouble with carbs or engine performance. Stihl says it contains alkaline additives.. Point is different.additives makes difference. Noticeable difference, IMO. Not a placebo effect.

Now, there IS one thing, though, unfortunately not easy to check out, where you CAN be screwed at the pumps....and it is getting to be a increasingly widespread problem here in the D.C. area. It's not the stations' fault...although they periodically inspect the pumps for this themselves. Hackers like to insert small credit-card scanners/readers inside the pumps where, unknown to either customers or station-owners, and deeply hidden down inside the pumps, these readers transmit sensitive credit-card data to the hackers. So, in some cases, your card-number could get into the hands of these hackers........with obvious consequences. I regularly use my credit card for gas, and have been lucky so far, and not hacked myself....but, to be totally safe, the best way to do it is to simply pay cash. And, with most credit cards these days, depending on the contract, you are usually only responsible only for the first $50-60 if your card does get hacked. Some card-issuers, for customer-good-will, even waive that charge.

this is a cool report. has a pic showing how no fuel contacts the intake valve (it shows one) on a DI head...also reiterates how consumers may associate grade with quality, a mistaken assumption. I can't tell you how many people do the same with an allergy to milk, and concluding lactose intolerance.
Net net is one would think that Top Tier is something, and the conventional wisdom says to use it. Again, since Costco is actually cheaper than most, seems like it's wise to fill up there. I'm willing to admit that 10 years ago, I could care less, despite the nice Top Tier brochure that came with my new 2007 car. Live and learn (but also more conventional stations are now included)...

Never had a problem with Sam's Club gasoline and really don't notice a difference when using other brands. Granted, I live in a warm climate and don't keep vehicles long enough to manifest the theoretical effects of non top-tier gasoline.

Around me there are Speedway stations all over. Probably more of them than any other brand. I use them occasionally but not too often. Their parent company is Marathon.

Marathon, though, is on the Top-Tier list, so it's possible (?) that that's the gas that Speedway stations are actually getting.

Anyway, my opinion of Top Tier has changed. That AAA report was pretty comprehensive in saying use it. However, with Costco 93 premium, it's a double whammy. Much cheaper for premium, AND top tier....so that's it for me....
(then again running my Nissan Maxima for 19 years on regular 87 whatever brand didn't seem to have harmed it, the fuel door says premium recommended)
