Exxon

Never use this car wash. Ever. It sprayed a corrosive material all over the passenger side of my car, causing permanent damage. The only way to get it off was to repaint the entire side of the car. Steer clear of this place if you don’t want thousands of dollars in damages.

For diesel owners, this is a hidden gem! At 2.899, it’s currently 10c cheaper than the cheapest I’ve seen in NoVA, and I see airport buses fill up here so it’s fresh. Gas, however, is on the pricey side, but given its proximity to the rental lots, it’s not as bad as it can be. Credit to the owners for keeping prices fair.
The Circle K portion: avoid at all costs. The coffee is terrible, the bathrooms are filthy, and the line for cashiers is basically anarchy. If you MUST eat/​drink, get Subway since it has its own register.

It’s an expensive gas station but it is also a very convenient one, as it is located inside the airport on the way to the rental car row. Easy enough to get into and out of, just not the cheapest gas you’ll find.

This is *the only* gas station that is right smack next to the remote rental car location at Dulles.
I didn’t want to pay the $ 9.90 a gallon fee for returning my car with anything less than a full tank of gas, so I went here to fill-​up instead. You’re almost forced to after taking the free airport access road because it’s so dang long.
They also carry healthy snacks that are cheaper than at the airport or what airlines offer. I found a couple of different vegan energy bars and some Welch’s fruit chews for my trip home.
For your information, they also have a full Subway sandwich shop inside.

Aight, its a gas station. I know.
But, I am always alarmed as I creep closer and closer via the highway to return my rental car. «Will there be a gas station nearby? We are sort of cutting it close to catch our flight? What will we do?»
Well, not to freak if you are flying Dulles. This gas station exists. Done and done, hope I saved you some gray hairs and/​or having to pay that ridiculous overpriced fuel charge that rental car places will stick to you!

Dulles Toll Road: You can go to hell with your rate increases! We were cool when you were just a $ 2.50 round trip. We were even okay, though on shaky ground, when you were $ 3.50. Now you are a $ 4.50 pirate whore and I refuse to ride you like the days before.
I have taken a new mistress. When Route 7 is busy I use the Dulles Access Road. It might add 12 – 15 minutes to my trip but it’s free. This Exxon lets me since the Access Road is for official airport use only and this gas station is on official airport grounds. I do buy something from the gas station but the point is that any money I spend is going to me in some form.
If anyone else is going to do this, just make sure you buy something with your credit card and take the receipt with you. They’re very good about it here. It’s busy, but they know the drill and keep things moving with extra employees at peak hour and plentiful (as it can be) parking.
And the great thing is they aren’t assholes. Being near the airport, and right by the other gas stations they still keep their prices low/​normal for everything from gas to food and drinks.
The seemingly unending asshole toll rate increases are actually causing me to consider moving.

This place is quite convenient for rental car, and it literally neighoring car return areas. The price is quite reasonable. I like it.

Great location for a gas station, and incredibly enough, it is not ridiculously priced! Despite a slight pump malfunction (pump clicking off before tank really full), we were in and put rather quickly.

Great location, but pretty busy. Good selection of stuff. Subway and RedBox located here too. Clean and spacious… and a good legitimate reason to visit the airport… without actually visiting the airport ;)

EXCELLENT place to go for repairs — Konate, the owner, was extremely friendly and helpful with my car, and charged a reasonable price for the area. I’ve got nothing to say about the gas (the prices seem kinda steep), but if your car has issues, I recommend taking it here.

Wow, this place sucks.
OK, so you are the only gas station near the rental car return area for Dulles Airport. Fair enough.
For the most part, people know what side of their car gas tanks are on but when you have a rental car, there is a good chance you will pull up to the wrong side. So have extendable hoses! Instead you have people in a rush, pulling up to the wrong side so they have to reposition their car.
This place makes me sad because it such an easy fix.

A perfectly fine place to refuel your global warming generator. The proximity to the car rental return can’t possibly be beat. So don’t blame me for getting hit with the $ 10 gallon penalty for not fueling up your rental beast.
The minus two stars is for the awesome soda offer. Buying 52 ounces of delicious soda water to go (yes a single serving) will score you free music (see photo). But alas the free music won’t do you any good since you’ll be in hyperglycemic shock.
