It is my ordinary practice to start with the positive things about a business and then discuss the negative. Potomac BP has two outstanding mechanics in Rick and the owner Brian Hannah.

I would encourage anyone looking for an honest mechanic to give Brian a try.

Cheapest gas you can get in this area. Most star I give because of this reason…read more The gas pumps a bit slower than normal. Otherwise a clean station, convenient place to fill up before hitting 495. There is discount of around 2% if you pay by cash but I get more points on my credit card, so I use credit card. YMMV.

Though it's a cheap gas station to come to, and it's right by the highway which is super…read moreconvenient; it (as a gas station) prevents me from doing the one thing I want to do most at gas stations, and that's pump quickly and get out heck out of there. I've literally never had a gas pump go so slowly. I think it took about 10-15 minutes to pump up my car. I felt like I was just waiting and waiting. It would pump 1 gallon in the time it would take for 10 gallons to be pumped. It's a universal rule (for me at least), that I always have to get gas at the most inconvenient times. I'm always in a rush somewhere, late to meetup, trying to beat traffic, or... well ya know: who wants to spend 15 minutes at a gas station. I want to be in and out. Until they get their pumps fixed, I can't see myself using this gas station. Sorry ;/

Cheap gas and open late!…read more This is my go-to spot to fill up gas when I'm in the Rockville area. I like the Liberty brand because the credit card price and cash price are the same (none of the misleading cheap cash price being advertised only to see the credit card markup that other gas stations do). Many times, I've needed to get gas late at night, and I've found the pumps at those brand name big company gas stations to be turned off and closed (which is frustrating because people need gas at all hours of the day, not just during business hours). I was pleasantly surprised to find that this Liberty gas station was still open after midnight. Yes, turning into or out of the gas station can get congested during peak driving times, but for the price and convenience, it's well worth it.

I hope this is not one of those too good to be true places. I have driven pass this gas station on…read moreseveral occasions and always wondered why/how are its gas prices so low compared to other places. For instance (as of the week of Jan 20, 2025), Liberty's regular is $3.099 while other places are charging $3.25+. Since my gas tank pretty much was below empty, I decided to give Liberty a shot. What do I have to lose....besides messing up my car? The process is pretty straightforward forward like any other gas station. I would recommend stopping by during off hours because this gas station is very popular due to its low prices. Sometimes, this can lead to a very cluttered situation in terms of entering and leaving the gas station especially since it share a parking lot with a 7/11 and a sandwich shop.

To figure out why the tire I have is leaking air, they sent me on my way with extra air in the problematic tire and told me to return when it leaks. No charge!

I've been filling up my back right tire for about 3 weeks now; it was leaking fairly slowly, so I…read moredidn't pay too much attention to it. Until... it started leaking a lot faster and I came out of my mother's house to find that my back right tire looked like... well... the opposite of Angelina Jolie's lips... (certainly not full). So I get to one of the closest gas stations to my mother's house and fill up my tire at the air pump. As I'm doing this, I see a mechanic tend to a Woman's car who had just pulled up out of nowhere. She just pulled up, parked in front of the garages and asked for help. He topped off some liquids, he checked the oil... and he gave her the all clear and sent her on her way. So... I waffled with the idea of going up to him for 10 seconds... and then I was like.. ( I'm gonna get stuck somewhere horrible and wish I would have gone up and talked to this guy) Enter Marco! The Picasso of parts, the Monet of mechanics, the John Belushi of car jockeys. He took one of his industrial jacks in front of the garage, jacked up my car and started inspecting my tire for nails. He felt around with his hands but couldn't find any nails. So he went and got a spray bottle of some soapy substance and started spraying it on the tire, smoothing it across the tire with one hand, and spinning the tire with his other. It was so methodical and smooth- it reminded me of the ghost pottery scene. *Cue Righteous Brother Unchained Melody* So then I got down there on the ground with him and hugged his back as we both spread the soap all over the dirty tire... methodically... slowly... fully, "Let the soap slide between your fingers" he whispered into my ear. Just kidding! But wouldn't that have been great. So, he starts seeing bubbles and finds my hole. Gets a plug, grabs his pliers, and his hole making thing tool and goes to town. I'm telling you, this whole process took Marco probably 5 minutes max. His broad and fine tuned brush strokes were so purposeful and beautiful. After that, he goes around checks the pressure on the rest of my tires, telling me they were too high, lets a little air out of them, and writes me up for 20 dollars. He fixed my 3 week problem in pretty much 6 minutes flat, and was so kind and friendly about the whole thing. I didn't have an appointment. He was definitely busy. He could have told me to: Vaya con dios. But he didn't. He wen't above and beyond and killed it. I will be going back to him, I gave him a 15 dollar tip, because not only was he amazing, he saved me getting a new tire. So really he saved me 100 dollars. THANK YOU Marco!
