Loving the new hours! Open at 4:30am. Can't be mad at cheap gas. Be sure to get that Costco Citi Card to take full advantage of all the gas savings. I stopped by before 5:30am and there were only 2 cars getting gas. I was able to swiftly get in and out in a matter of minutes. Thanks Costco!

LIterally , here is "Johnny on the spot!"  - You can recognize John by his bright sunglasses and even brighter smile.

I think this is the first gas station we have ever reviewed- and it's nice to be able to say an old quote, "service with a smile" - which was true for this young man who seems to be everywhere at once! His name is "John" and today when asked if he could help with our gas card, he was "Johnny on the spot." It's great when we are reminded of a time when folks really did want to be of service.

Located in Mission Valley; 2345 Fenton parkway, San Diego, CA 92108. This location is very very busy; I try to go before 7am because the gas line wraps around the block. Decent prices for Costco members. I believe they open at 0530; they have attendant around to help in case you need them. It's right behind McDonalds. I like that they have neon sign on top of the gas pump to let you know if the spot is free or occupied. Usually green for a free spot or red for being occupied. Thanks for reading my review, have a fantastic day!

COSCTO GAS, MISSION VALLEY! This costco gas is always super helpful, extremely easy to locate and go through. The people there are always nice if you need any help, the gas is cheap ranging from Regular $4.26. I'd highly recommend going through the week days and never on the weekends. Sundays are the worst for gas days where there's an intersection to get on the right furthest lane for gas, and there's two lanes to enter, making it super slow, and wasted time sitting in traffic. Other than that, the price is good, parking is easy if you go around Costco, and it's always clean, and easy to navigate through lines.

In my opinion, I think Mission Valley's Costco line for gas is organized to make it easier to get in and out of the gas fueling pumps/stations. There's ONE destination line just for refueling! Costo's lines for gas in Rancho Del Rey are AWFUL!! At Rancho Del Rey, cars are trying to "pass" the Costco lines the same time cars are trying to turn into the gas lines can be so hectic !!

I like the early opening hours and the line goes pretty fast. If I lived a little closer, will definitely be a regular customer here.

The person was kind and I enjoyed the selection of snacks, beverages & liquor. The beer was cold…read moreand the customer service was on point. I found the store to be clean and relatively conveniently located. I appreciated the information provided by the person working there.

I want to First say that this Mobil station is way overpriced, the price for regular unleaded was…read more$5.69 tonight. I normally would not go to this Mobil due to the price but tonight there was a detour and I desperately needed gas I wanted to buy $1 worth of gas so I could make it to my regular gas station where the last time I purchased gas the price was $3..95 per gallon nearly $2 less per gallon then the Mobil station. I was informed by the male cashier that I could not purchase $1 worth of gas that I needed to purchase $2 worth of gas . I was tired hungry and just wanted to get home so I purchased the $2 worth of gas gave him my opinion of him and the policy. I decided to share my experience with everyone on Yelp. $1 of gas that I wanted to purchase the male cashier for me that I could not just buy $1 worth of gas I had to buy $2 worth of gas. I wss tired hungry and just wanted to get home so I purchased $2 worth of gas, and my opinion of the policy and him. And decided to share my experience with everyone. There is a Shell gas station right across the street from the. Mobil, I encourage everyone to go there instead. Happy Travels!

Free air and water at this gas station. Wasn't busy on a Sunday afternoon. Close to the freeway…read moretoo. Be aware of surroundings though. Saw a guy peeing on the corner of the street so that was weird.

Stopped by this Chevron on University Ave and had a pretty disappointing experience that I think…read moreother customers should be aware of. On 03/25/2026 around 9:36 PM, I made a small purchase (~$8) and paid with a $50 bill. The cashier listed on my receipt, Imelda, questioned my payment and repeatedly asked if I had smaller bills or could use a card. That already felt unnecessary, since cash is accepted and breaking a $50 for a small purchase is standard at most gas stations. What stood out more was the change I received. I was given $41.92 mostly in $1 bills, even though larger denominations were clearly available. As someone who has worked at a gas station before, I understand how registers and safes operate, this didn't feel like a limitation, but more of a decision that prioritized convenience over customer service. This isn't about the money, it's about the experience. Situations like this slow things down, make customers feel unwelcome, and reflect a lack of basic service standards. For other customers: just be aware you might get an unnecessarily difficult transaction if you're paying with larger bills. For management: this appears to be a training issue. Employees should be equipped to handle common transactions efficiently and fairly without pushing inconvenience onto customers. Hoping this gets addressed, because it's an easy fix and would make a big difference.
