They take my card and are on the way to and from work.
Basically whichever is closest or most convenient when I think it is time to refuel. I don’t usually wait for the low-fuel indicator, though.
I said price as one of my choices, but it’s more-nuanced than that. I try to find a place with the smallest difference between regular and premium. The turbo demands premium, and my scrotum gets all tense when stations try to make an extra 50 cents / gal. Most of the places where I routinely stop have a 25-35 cent delta between the flavors, but I really don’t know what their base price (for the regular swill) is.
I could have also voted for “ambiance”, as I just like the feel of some places. And I almost never go into the store; I only stop for gas.
Along with location, my decision could be made on the place’s specific layout. Its ingress/egress may flow better, especially depending on my route of travel.
Anecdotally, I have filled-up with all brands (and non-brands) of gasoline and have never had any ill effects. Additionally, I’ve fueled when the tanker was re-filling the vats without any ill effects.
They let me pump before paying and have free air.
I almost always try to use Shell, because I know my engine will run well on it (and I use premium too. so yes always on the lookout for the stations which have the lowest markups on premium). No reason to gamble with other brands.
GasBuddy is a site I always check before I go out on a gas run (they have mobile apps too)-the prices at local stations can often vary by more than 10 cents/gallon for their premium prices (and forget the airport, there we are talking about 20-30 cents more!).
Price, primarily. But not entirely.
There’s a gas station that’s the closest to me, and easiest to get to. Incredibly convenient. But here’s the thing: they are right by a freeway entrance, and as far as you can see from that vantage point, there are no other gas stations around. Their prices are always a good 50-75¢/gallon higher than the average, no exaggeration, clearly to take advantage of that fact. They must figure people getting off the freeway, or needing to get on, won’t see any other options, and being desperate, will pay the extra money.
If you drive another maybe half mile down the road, around a bend, there is another station with much more normal prices. Even though it’s not that much further to drive for me, it’s much less convenient, because you can’t easily get on the freeway going the way I normally have to go from there (there’s no entrance to that direction of the freeway going that way on that road). So it probably ends up taking me a good 15-20 minutes longer to use that station. But I always will. Not because of the money, but for the principle of it, because I know that first station is trying to gouge people because of their location. Screw 'em.
Price and location - they really go hand in hand. Our tank is just under 20 gallons, so a 5¢/gallon difference is less than $1 on a fill. I’m not going to burn $2 in gas to save $1 on a fill-up. But in an area where there are several stations in close proximity, or if I have to run an errand that will take me close to a cheaper option, that’s where I’ll go, unless they’re crazy busy.
I have no brand loyalty, altho I avoid Citgo because Hugo Chavez pissed me off and I don’t want Venezuela to get any of my money if I can help it. 
Beyond price and location, I like places with easy in-and-out, and sometimes I need a place with a convenience store so I can get a caffeine fix.
Price and and the lack of lines - plus taking credit cards. There is a cheap place near me, but it has only two islands and four pumps lined up in a very narrow space. It being the cheapest place around means it is always congested. There is another place I can go to on my way home from work with the same price to a penny but with plenty of islands and plenty of room. I choose that one.
He’s dead, Ma’am.
:rolleyes:
Generally whatever falls along my route. I pay attention to price and will go to the cheapest along the way. I do not go out of my way to go to a cheaper place. My times worth more than the dollar I might save.
I avoid places that charge a different price for credit cards.
I will never return to a place that charges a fee when it’s done as debit. Debit costs the vendor less than credit and they return the favor by charging me more, those places can piss off.
Usually I just fill up at whatever location’s convenient. Occasionally price is an issue, like if the prices have jumped up at some stations but not yet at others. Pay-at-the-pump is pretty much standard everywhere; if it wasn’t available at a particular station, I’d probably go somewhere else.
If I’m out on the road, I might look for a gas station with a store attached that looks clean, well-lit, etc.
Nauplius mentioned free air. A few years back I was driving around for a while with a slow leak in one of my tires, and that was definitely a consideration then.
If I’m near a Giant Eagle I get gas there due to my loyalty card discount. Realistically though, I fill up wherever I am when the warning light comes on.
I’m lucky that the Exxon station closest to my house has a very competitive price. I also fill up at Kroger because of my Fuel points earned from buying groceries.
I guess everyone knows to avoid stations near the Interstate off ramps? They are always a nickle to a dime a gallon higher. Sticking it to the tourists.

My own driving is entirely commuting, so entirely predictable. I literally drive 95% of my annual miles on exactly the same lanes of exactly the same roads, both ways.
As such, so is my refueling pattern. So, I always pick the same station on or about the same time in the two-week refueling cycle for my car (top off just after payday, splash some more in at about one week after payday).
Gas prices are not very variable in the area, so there’s no advantage to shopping around. The station in question is approximately a 100-foot detour from the never-varying commute route.
Location/Price. I pull up the map on austingasprices.com and follow the route I’m about to drive. Usually the route to/from work. I find the best price with a Techron brand.
I have old vehicles.
I go out of my way to get non ethanol fuel.
Higher the octane, the better.
I am retired, no daily commute.
I have an irrational hatred of going to the gas station. So my main motivating factor is “which station will provide the least hateful experience?”
So I choose mainly based on convenience. Sometimes price if I notice something seems high and there is another station that is similarly convenient. I don’t know of any that don’t take credit cards.
Since we don’t have self-serve in NJ, another factor comes into play - How surly and slow are the attendants? They’re usually pretty surly and slow, but if a station is worse than usual and I remember to avoid it, I will.
If I’m not in New Jersey, I usually stop at one with a mini-mart. Bonus points for a roof over the pumps.
I get “gas points” for shopping at a certain supermarket, and for every 100 points I get ten cents off per gallon. I often save over a dollar per gallon.

I’ve heard of gas without ethanol. Other than Sunoco’s race fuel, which is sold at a few oddball gas stations near race tracks for insane prices, I don’t think I’ve seen “pure” gas in about 15 years.

There are stations that don’t take credit cards?

Around here, Arco stations get weird with what they’ll accept. No pay at the pump either - you have to go to a kiosk or inside, and if they accept credit cards, they charge extra.
When I notice that my fuel guage is low, I start looking around for a station. I probably fill up about once a month and don’t give it much thought.
