Pros: Convenience. This is at the periphery of the airport, right at the end of the road featuring all of the rental car places. It is also the only gas option for literally miles around. Depending on where you are coming from and your familiarity with Denver, you can gas up elsewhere. But for sheer convenience, it is hard to beat this place. They also have a fast-food court if you want a quick coffee or snack before returning your rental car. Cons: The parking lot is sub-divided to route you into the fast-food court, so accessing the pumps from some entrances is a pain. Prices for gas may be a bit high, but are certainly a bargain compared to letting the rental places gas it up for you. The fast food place was super-busy, and they have limited selection of things like Dunkin Donuts. I'd fill up here again if I were returning a rental car to this airport. read more

This place is a car wreck waiting to happen!! Cars weaving in and out, turning here and there and everywhere, more people coming constantly and no where for them to go! Open another gas station over here please before some one gets killed! What a complete horror! I felt as if I was in a modern version of Mad Max!! All that was needed was a couple of guys with Mohawks and football pads to be yelling and shooting arrows and it was on! Gas is way high... but of course if your the only game around you can charge what you want. Seriously though... just give people an option... it might save lives! read more

Conoco - Ouch! - Gas Stations Near Me - Denver, Colorado

The BEST candy and snack selection I've ever seen! they had flavors of Haribo gummies and pringles that I didn't know existed!! and they had RESES animal crackers which I've never found anywhere except Costco!!! you should leave a review if you love their candy selection too!! read more

Probably the worst gas station convenience store staff members I have ever encountered. The two I encountered both reeked of pot. Guy behind the counter completely ignored anyone standing in line. Didn't say a word when I finally walked over; he just rang things up and stood there. When I asked for a receipt, he looked at me like I was a jerk for even daring to ask for something so beneath him, then turned away and just stood there. It's nice that the airport has a gas station and food options at the cell lot, but this place was just awful. read more

This is the gas station/convenience store that you always hit upon your return to Denver International Airport on your way to drop off your rental car. You can quickly gas up and then drive down the street to drop off your rental car. I've been here twice in the last couple of months... You'll need to be careful in this parking lot, this is the busiest filling station I have ever been to, so watch out and make sure no one runs into you and vice versa! read more

Awesome spot. This is probably the most confidently located gas station for a rental car returns I've ever seen --it's immediately before rental returns. Nice job Denver! Extremely clean facilities inside, and plenty of gas pumps. Been here on several occasions and always have has, and prices are inline with local stations. Awesome spot! read more

Only gas station near the rental center and it's okay. Easy to get in and out of, convenience store if you need some processed crap and decent fuel prices. read more

Omg!!!! Don't come here if you're in a rush they have the slowest damn gas pumps on the face of this Earth. I've been pumping $22 worth of gas for about 10 minutes now. I have typed out this review and it is still pumping, mind you the only reason I started typing this review is because the gas was already moving slow. read more

Conoco - Gas Stations Near Me - Denver, Colorado

Wow this place has all the drinks and more when stopping in after a long flight, highly recommended read more

See all

Slow gas pumps and the automatic receipts never work. Ended up missing my flight because I had to wait in line inside to get the receipt!

My previous review for Conoco gas station is being updated as this time I went inside the store and was astonished and amazed at all the service and food options available inside. There's simply tons of snacks and drinks. There's even a hot food area! A special mention to the bathrooms, which were very nice and clean and (yay!) they used nice comfy toilet paper too! Note: am not including this in my Yelp 100 challenge for 2016 since it's a revisit and not a new place read more

The closest gas station to the airport. It didn't help at all! THEY RUN OUT OF GAS AT 6pm! Huge potential since they're the only one around with the next station 10 miles away. Tons of people heading to return their rental cars pretty upset the day this happened. We had three hours to spare so we weren't in trouble but we weren't happy either. read more

Chill people working the constant stream of customers... Good place to wait at if you're picking someone from DIA . Found myself here burning time cuz the fiancées flight from LAX was rerouted due to weather. Staff here was friendly not giving me any issues of hanging out. I actually got to talking with one of the employees and we had a real nice conversation. It sure beat waiting in the car by myself which I saw loads of other people doing. Note: they sell coffee refills for just under a buck and there are electrical outlets under the window bar (was able to charge up my phone while I waited :-D ). read more

Conoco - Coffee, window bar, & busy gas station. - Gas Stations Near Me - Denver, Colorado

DO NOT WAIT TO BUY GAS HERE!!! Plan ahead and save yourself $$ and headaches. This is one of the worst cases of gouging I've come across. TODAY 7/20/17 regular was $2.43 a gallon at the airport ConocoPhillips. Denver gas prices average 2.10 to 2.15 everywhere else with Costco being $1.97. The receipts paper is ALWAYS empty and you have to go inside every time. The lines are ridiculous and pumps are usually down read more

This place sucks now!! Whatever happened to the good workers who used to be employed here? I had called in once and this girl answered the phone and I had a question about some specific pills for allergies and she was "I'm very busy, can't assist you, you'll just have to come in on your own time." See, in my job, if I said that to a customer, hell will break all loose! In fact, they switch workers like crazy. Good people... Outside of work. But on the clock, they cuss, yell and play around saying derogatory comments about random shit and in front of customers! Horrible customer service and a bunch of immature workers. I hate it here. read more

Convenient and near the car rentals and not overpriced as some of them can be. I appreciate that. We could do this instead of getting gouged by Advantage. read more

***This gas station is right next to the rental return at Denver International Airport so it gets unbelievably busy; to save time, you are much better off getting gas a few exits before the airport; this gas station does feature a large convenience store with lots of snacks, candy and drinks (unfortunately, their Wrigley's Doublemint gum was quite stale and hard--kind of like the gum they used to include with packs of baseball cards); the staff was very nice*** This gas station has several free parking spaces available if you just want to to pick up a snack or drink at the convenience store. read more

Stopped here to fill up our rental Prius before getting to the airport. Pay at the pump was down, so I had to go in and stand in line. Their machines inside were not working correctly, so the clerk had to "hold" my credit card while I went back outside to pump. I had to then go back inside for him to charge my card. Weird. Unorganized. Chaos. read more

Because the airport is so far away from Denver proper, everyone needs to get gas before turning in their cars to avoid the Super Power Violation that they'll throw down if you're a sliver below the F on the gauge. Everyone needs gas, so they're all here gassing up all at once. Like 100 cars at any given time. Sometimes more. Have your credit card quick-swipe skills honed and ready. You will need them. read more

When you've got a major city airport 19 miles away from the city -- you're pretty much monopolized as to where you need to refuel your rental car. And this station is pretty much all that there is. So be ready for LONG lines of gas customers and higher prices. The air machines are kinda lame -- it took my money and no air. Booo.... :( read more

Don't count on them providing a receipt for the gas pumps. Wish I had known this before filling up my company vehicle with gas. Thanks for the extra inconvenience! read more

The gas is pretty expensive, and the gas pump asks like five questions before you get pumping: car wash, membership number, etc. inside the bathrooms have been hit or miss as far as cleanliness and the service as well. I would recommend going to a different station unless you are desperately out of gas. read more

Conoco - The storefront - Gas Stations Near Me - Denver, Colorado

This gas station clearly has a monopoly on both the rental car and airport visitors. It's the closest gas station to the airport for miles. In fact it's the closest gas station for a couple of miles until the 85 on the way back up the 470. However, last time I went to get gas I had a little more than a quarter tank and opted to just drive on. The line of cars waiting to get gas was about 50 cars of everyone trying to fill up their rental cars. Yeesh. read more

The yelp pin is in the wrong location on the map. It is right next to Final Approach. My only advice is... Do not, I repeat, DO NOT plan on taking a #2 here. Let's just say there are flys in the stalls. That said I would also suggest not to try their fresh food either... This place is filthy and disgusting. read more

There's something wrong with this station. Now the third visit where the pump keeps atopeven though I know I need to fill it more. Then I tried 2 other pumps but my card wouldn't go in. Having previous experience with skimmers at gas stations I'm wary of that resistance when inserting the card. I wouldn't recommend coming here - haven't had great experiences. read more

UGH. Obvious monopoly on gas because it's right next to the rental car offices (far from the airport). Of the three stations we ended up using, one operated VERY slowly, one got stuck and kept filling even though we didn't want it o, and one didn't work entirely. Not to mention, pricey. Compared to California prices, it's reasonable, but compared to Colorado prices, it's such a scam! Do your best to fill up before heading out to the airport, if you can. read more

Rude employees. Refused to provide a receipt for my gas purchase using a company credit card.

Worst customer service ever. The blonde woman working the register this morning (04/20/16) was clearly unhappy with her job and was letting it show to the customers, to the point of rudeness. I'll remember to get gas somewhere farther from the airport next time. read more

Doesn't allow visa or American Express or anything with a chip! outside. 100s customers pumping and one cashier?? Then, I had to leave my card inside and they purposely slowed my gas, running half as fast as other pumps. Stop somewhere else, this place is a shitshow. 20 plus minutes to get gas!! read more

This Conoco station is great for refilling your rental car right before returning it. It's very conveniently located right next to all the car rental company lots. The station is clean and modern with many pumps available. read more

This gas station is not maintained well at all... One of the employees always smells terrible Everytime he works and the bathroom was filthy right after someone just cleaned supposedly... Terribly run read more

Highway Robbery! I was in Boulder last week for a day. I rented a car at the airport after arriving late. In the morning, I noticed that gas prices in Boulder were in the low to mid $3.80s. I figured that the airport Conoco would be ten cents higher. IT WAS $4.29!! This is robbery. I hope that the city, county, state or some school system is taking a lot of tax revenue from that place. There is no gas station that should be allowed to make 40 cents a gallon in profit. As the other reviewers mentioned, this is a really busy gas station. Be warned! Watch your wallet! Put your wallet on the hood and your hands in the air! read more

They were too lazy and busy talking amongst themselves at 1 am to get some hot dog buns for their customers because they were out. Terrible convenience store service. read more

Gas is good because it makes my car go. They sell gas. However, they are expensive.

Expensive, but so thankful for the location. I nearly ran out of gas after dropping off some family at DIA. I was willing to pay the price after my dumb ass didn't remember to make a gas stop beforehand. If you don't want to pay more, think ahead and fill your tank before you go to the airport! read more

This Conoco is the slowest gas station that I've ever been to. They lucked out with traffic because they're the only gas station near the Denver airport. It took us almost 15 minutes to fill up 7 gallons of gas, and it wasn't just our pump station but everyone else's pump stations that was just as slow. read more

Bathrooms are disgusting! Toilets clogged, trash everywhere, no toilet paper, flies. Filthy. The inside of the station was the same...dirty counters and trash on the floors. read more

I'm down with a little price gouging at the crowded airport car rental return, but when the pump starts blaring television commercials at me, I get the message: this station has too many customers and has resorted to desperate means to drive them away! read more

The Conoco right outside of the Denver airport is a little pricey but it's a nice, clean place to stop before returning a rental car or before hitting the road to your final destination. read more

Great, convenient place for a pit stop. It has food, gas, etc. However, they gouge you on price. You can find gas MUCH cheaper not too far from here, but because of their proximity to the airport, I guess they take advantage of the consumer. Next time in Denver, I'll get gas elsewhere. read more
