Horrible customer service! Went to get gas today and the pump is unusually slow to fill the tank,…read morebut I didn't think otherwise. It took almost 10 minutes to fill the gas tank and after awhile, I start noticing gas coming out of my tank. When I pulled it out, a puddle of gas came out. Then I notice it's like 11.5 gallons on the meter and my car is a small car, the max gallons are probably 11 gallons to fill my car. So basically instead of stopping by itself when the tank is full, it kept filling and eventually spilled out. Complaint to the gas station attendant, said there's nothing that they can do. Didn't even offer to refund the extra gallon money to me. It is very sad as I go to this gas station frequently and it is close to my home. Now I will go somewhere else!

This used to be a decent gas station, but it's gone downhill a bit in recent years. They used to be…read moreone of the first Arco stations to accept credit cards for store purchases and gas, back when the corporation only did debit with fee or cash. They also used to have very competitive prices, only 8c above wholesale, which is below industry average. Their warm food used to be fresh and organized, their cooler well stocked and their restroom free and clean. When they ran out of regular, they would lower the price of premium to regular to keep customers happy until the delivery truck showed up. It used to be a 5-star business 10-20 years ago. Now they have fallen off the wagon a bit. Employee moral seems down and service is lagging a bit. They still have some pluses, but it's a mixed experience now. Sad to see this location decline.

OK service and alright prices on gas at times. Employees are…read moreneither friendly or unfriendly. (Just a body there) inside and outside could use a nice scrub down for sure.

It took 4-5 times before o posted this but clearly their management is not on the same page. Don't post "open 24 hours" if you're not truly 24 hours. They need to include their shift change. Too many times this has come up where I couldn't get gas, snack, or essentials. I'm over it and management needs to step up.

Was staying at a hotel across the street from this Costco gas station, so I was able to take…read moreadvantage of an early morning fill-up before this place got too crazy. Solid spot! Wide lanes makes it easy for big car and small car drivers alike to navigate through. This Costco gas station is also located next to a Costco Business Center (so not your regular type of Costco) - which helps I think with the smaller crowd. There was no wait at the time I stopped by (a little after 7am on a Sunday). Prices as usual is always great - $5.39 for premium at the time of this review. No issues with the pump other than it not reading my mobile app membership QR code, but luckily, I had my backup card with me. The service attendant was present keeping things tidy. As I found out during my recent stay - there's also a Starbucks and yummy poke bowl spot in the same shopping center.

Wide lanes so that you can navigate around other cars to get to an open spot and even on a Sunday afternoon, there was no line to get gas with so many pumps available. Costco has always been known to have really affordable, cheap, but not watered down gas, so it's a god send for people who are members. I honestly think my only issues were that it didn't take the app version of our membership no matter which pump we tried and we had to talk to a team member to manual activate the pump and get our membership ID number. Also, the Internet connection near every Costco is infamously awful, so there's that too.

My favorite Arco in this area and here's why:…read more Location This Arco is located off of mission and grove and it's very spacious with lots of gas pumps. Some times it gets a little crowded during peek hours but the low gas prices are worth the wait. Prices I know it's not the best gas to put in your car but when you go on a Ralph Lauren & Versace shopping spree, this place doesn't seem so bad. Gas prices fluctuate with the economy but overall this is one of the Arcos in the area that offers super low rates per gallon. ampm This Arco has an ampm where you can find a rather large selection of snacks and libations. They have some pretty good deals on snacks and drinks here. It's also clean so you don't have to worry about roaches or vermin. Customer Service I've never once been mistreated by any of the employees here (knock on wood). I'm always greeted politely when entering the store and I have no complaints about any of the employees (good management at this place). So if you are ever in need of gas and don't want to spend a lot, stop by this Arco. It has the best prices in town!
