They consistently offer some of the cheapest gas prices in the area. The setup is organized and easy to follow: get in line, wait for the pump light to turn green, then pull up to the correct pump when it's your turn. The onsite staff are also helpful and keep things running smoothly. It does get extremely busy with long lines, so it's best to avoid peak rush hour times if possible.

I love the fact that they have good gas and at a reasonable price. This tends to be one of the…read morebetter priced gas stations in the area. Even compared to other surrounding counties. Just keep in mind that this is one of the busiest Costco gas station there is. It's always best to go either super early in the morning or late at night. They remodeled and added more gas pumps recently.

This is a car wash review only:…read more I was in town and needed a car wash. I didn't want to get out of my car so I had to find one that would let me stay inside. You know, like a drive thru wash. I found one in Concord to my relief. The Arco had one and this was one is a little different than the ones I have been to before. You have to pay the cashier for the service before you get the wash. I paid $14.99 for the regular wash. It's the cheapest one! Drove up to the wash area to see two workers waiting for me. They scrubbed down my car before the machine brought my car into the wash itself. Remember you need your car in neutral. I don't know why but I love the sound the wash makes. Love the feel of just sitting as the machine moves your car! After the wash and rinse, I was put to the outside! Another worker was waiting for me, by his lonesome self, he towel dried my car. Loved that my car is finally clean! 5/5

I saw this arco has a car wash and I decided to pull in to get a cheap one done, however I was…read morepleasantly surprised because I basically got a hand-car wash + help from the mechanical machine style wash! They have a couple hard working men wash your car and tires by hand, then you go in through the car wash. At the end, they towel dried my car! I felt bad because I didn't have cash to tip, but I wasn't expecting this service. I appreciate the guys who were there doing this! Thank you!!! My car wash was the lowest priced one. $14.99, but it came out better than most upper priced washes I've paid for in the past (gas station ones). The inside machine wash does look outdated and is a bit small inside- maybe that's why they wash this way with man power and the machine - but I was happy with my service today!!

Stopped by here to get a quick car wash and ended up buying the monthly special for 6 car washes…read more Michael was the attendant inside and was very helpful and very patient to go through the different car washes they offer and helped set me up once I downloaded the app. There was a couple before me who was also interested who also bought the monthly car wash and he was very patient helping them and explaining how it worked. Good guy. I've come across many workers and they're usually pretty abrupt and don't take the time to explain like Michael did. It took a while and without his help I'm sure the couple and myself included would've just walked away. A big thank you to Michael for all your help!

What a garbage approach with their car wash. "Touchless" apparently means it doesn't touch the…read moredirt. Came out after my $22 wash job and the car still had a film layer of dirt all over it. I went in and asked for a refund, the guy working the counter told me to look at the receipt, that it says "no refunds." I responded "It also says 'Car Wash.'" ‍ He offered to give me another wash. It came out the same way. What a rip off. YOU DON'T GET WHAT YOI PAY FOR HERE, and management does not stand behind their lackluster product. Get it done somewhere else.

Gayle and I were returning home for Dinner last night and we needed to buy some gasoline. I like to…read moreplay the "E" more than she does, and I figure I could have gone another 20 miles on what was left in her Hyundai's tank. However, it wasn't worth her anxiety to push that opinion any further. The Bonus was the 45 cents/gallon discount earned from all that Holiday shopping at Lucky. That reduction down to $3.12/gallon looked pretty good as the dollars on the pump sped upwards. Speaking of bonuses, here's a few associated puzzlers: - At current gasoline prices, what's with the 9/10s at the end? - Taxes are a large part of the per gallon gasoline price. Where does that money go? - Why do some nozzles have catches on the handle (for auto filling) and some don't? - Why is it when you need gasoline, the nearest service station is "always" on the other side of the road? There could have been a Seinfeld episode about one or more of these burning questions....
