Costco Gas Station is a membership based fuel center offering Top Tier rated Kirkland Signature gasoline, known for its quality and engine cleaning formulation. It consistently provides the lowest cost and best gas prices in the area, especially for premium fuel. While there is often a bit of a wait due to the prices, the lines move fast. The associates are described as pleasant, professional, and graceful under pressure. Members come for the discounted, high-quality fuel that is reliably fresh, viewing it as a key perk of membership.
I love to go to Costco for my gas because the price is awesome and for the nice people that work there! ????????

87 is a great deal if your car takes it considering you're getting 5x detergents compared to regular gas. Steady stream of customers which means you know tanks are filled frequently so low chance of water. Staff very nice and took a moment to wish me a pleasant day when giving the receipt which I appreciated.

Love coming to this gas station. 3 cars are able to gas up at the same time and its always cheaper than the north plainfield location
