Worthless as a fueling stop. This gasoline station is currently defunct for the purpose of selling fuel. The owners waited too long to make changes to be compliant with California law passed back in 2014. So they ran up against the deadline for compliance that came and went back on December 31, 2025. Look elsewhere for your fuel needs.
This station has been closed for many months. Does not show any sign of being reopened any time soon. Lots of tanks maintenance and soil work in progress.

I love Costco Gas Stations, but be aware that the prices between the two Stations Im South San Francisco can be different. Usually the Airport Costco Gas Station is cheaper than El Camino, but sometimes El Camino is cheaper. I always check Gas Buddy to see which location is cheaper first. If the prices on Gas Buddy have not been updated in a while, you can check the prices in the Costco App by changing the warehouse location, but thats rarely an issue because Gas Buddy users tend to do a good job of keeping the prices up-to-date for both Costco locations.
