Costco in Marana (3901 W Costco Dr)

Consistently Lowest prices around

Costco gas is notoriously bare bones. It's get your gas and go, which causes some waiting at times because they tend to have lowest prices. That is the benefit; lowest prices! If you want to clean your car, go to a car wash.

Premium is only 91 Octane.

No window cleaners or air

Showed up 15 minutes before they closed... BEST time to gas up, bc there's NO WAIT TIME...!! :D

Wish it was 24 hours!

Long lines move quickly. worth the 20mi drive to save 30 cents per gal. great for fill-up.

Always clean and associates that are helpful.

It's Costco. They do everything well.

Awesome service at the best prices for gas!!
