Not sure why they have Gas attendant standing at the pumps. They are quick to give you a dirty look when there is an open pump and people in line refuse to drive around and existing car to get to the pump that is open. But they take no command over the situation and help glide traffic. I get it if its not there job to do so, then don't get upset and give dirty looks when a customer does it. This place is always a hornets nest and a riot ready to break loose.

No diesel. I read and looked to see if they offered diesel. After not finding an answer I looked at the pictures. I noticed a few green signs on the pumps. Figured they read diesel. I figured wrong. Upon arrival they read eye wash station.

Even on weekdays, there’s always a line at Costco gas — that’s how you know it’s worth it. The prices are consistently among the lowest in the area, and the quality is solid. The lines move fairly quickly thanks to the efficient setup and helpful staff. If you go with a bit of patience, it’s still the best deal in town. Worth it every time!

Merced is a smaller gas area, very tight space. Line moved quickly.

Everything is expensive in California. The unit price at a COSTCO gas station is about $4.20. You can save a little by adding or subtracting. If you share the international membership card with others, it will not be able to be scanned. You have to find an employee wearing a vest to help swipe it before you can add it.

For me, Costco gasoline is the best. I always fill my cars at Costco and the price is better than any gas station, so I highly recommend them.
