One of the better Costco gas stations I've been to and unless you're coming on the weekend, there is usually little to no line. Even when there is a line, it seems to go much faster than other Costco stations that I've seen and I'm never waiting more than 5-7 minutes. They have regular (87 octane) and premium (91 octane) at some of the cheapest prices you'll see in Vegas, especially on the premium stuff. I used to drive down here to fill up when I had a vehicle that took premium only because the pricing is typically what you'd see for the mid-grade stuff anywhere else. That's a big difference!
