Costco in Rancho Cucamonga (11800 4th St)

I work right by there and always try to fill up there. Some say it's cheap quality gas but who cares, it's cheap.

Literally the cheapest Costco station throughout SoCal. Recommend going early in the day or right before they close, lines get very long during the evening.

Best prices, but only accepts visa credit. And you must have a Costco membership.

Great prices compared to competitors!

This Costco always has a higher price than OC Huntington Beach Costco! Why? Cost of living is more, but gas prices are lower in HB

Mon - Fri 5:30am to 10pm Sat. 6 am to 8:30 pm Sun. 6 am to 7:30 pm Please up vote this, until GasBuddy adds hours to station information Great station, Got to love Costco gas!!!

Excellent service if you need help at the pump.

Very clean and nice, best time is morning or before close

The guy walking around if you have any questions or need help, is really convenient

Just please gassers, pay attention and keep it moving g forward timely, you have others that need to get gas and don't have all day to wait for you.
