- GGGerardo (Gerardo)Apr 25, 20265.0Great gas prices in town. Competitive prices, many times the same price as surrounding Costcos. In one occasion, I couldn't start my car beacuse of low battery and the owner came out and gave me jumpstart and I was able to make it back home. Very friendly and kind customer service. Recommend!
- BBBill BlotbinDec 24, 20252.0This station does not support Sinclair app “pay at pump” feature - only debit or credit. Pump interface needs maintenance and updating. Cashier wouldn’t help - not a good experience, overall.
- FMFrancisco MedinaSep 12, 20255.0Top tier gasoline at a great price! Usually on par or better priced than Costco. Better quality gas than the stations in the area.
- DSDolores SalasAug 26, 20251.0They cheat you be careful I paid debit and they charge you like your using credit every where else when you use debit you get the gas like you pay cash here they charge extra pay attention
- JVJules VerneMay 21, 20251.0The male manager with the name Hasan or something is incredibly rude. I have visited multiple times, and he either gets my pump number wrong, or how much gas i wanted. He is so disrespectful, the gas is cheap but I avoid this place. This guys charging me more gas than I asked for and then getting angry at me when I ask for the change back.
