Top 10 Gas Station & Cheap Fuel Prices in San Mateo County, CA

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.
