Costco Gas Station is a membership-based fuel center offering Top Tier rated Kirkland Signature gasoline, formulated to clean engines. The fuel is considered good quality and is typically priced very competitively, often being the cheapest option for members. The station setup allows for an easy entrance and exit. The pump station is noted as being absolutely the cleanest, with staff consistently cheerful and friendly, making rounds to clean debris and wipe down pumps. Attendants are described as super friendly and helpful. While the fuel cost savings alone can pay for a membership, prices are noted as not being as competitive as in the past. The station is almost always very crowded, requiring a wait for a pump. The specialized fuel nozzles can be tricky and must be pushed in all the way to operate.
