What is the best day to buy gas at Costco? ›

Gas stations can get busy (avoid weekends)

Avoid weekend fill-ups if you can. Buying gas on a weekend could be a nightmare, as waiting times could take hours. To avoid this, the best time to get gas at Costco is on weekdays between 10-11 in the morning.

Costco opened its first gas station in 1995 with a commitment to members to provide high quality gasoline at the lowest possible prices. Members will find regular and premium grade fuel – and in some places, diesel. High quality fuel – it's another benefit of a Costco membership.

Q: Where does Costco get its fuel? A: Costco buys fuel from major refineries and distributors in each area. All Kirkland Signature™ Fuel is guaranteed, just like the merchandise we sell inside the warehouse.

Costco gas is offered at a great price

Although the exact amount of savings you'll get varies based on your location and the specific club you're shopping at, you'll typically save around $0.20 per gallon at Costco according to most online reports. Most cars hold between 10.5 and 18.5 gallons of gas.

Buy Gas on Monday or Tuesday

Be strategic about the days you fill up at the pump. “For gas, Mondays and Tuesdays tend to be the cheapest days to fill up your tank as demand is lower at the beginning of the week,” Anderson said.

Costco fuel stations are well-maintained by our capable attendants so you may be confident that the fuel going into your car is clean. Costco uses fuel filters in the petrol pumps to catch particles or debris larger than 10 microns in diameter. For comparison, the average human hair is seventy microns thick.

If you're looking to save money on gas—or anything car-related, including tires—Costco is the way to go. In fact, Costco's gas prices are the lowest in many states. So it makes sense that customers wait in line (sometimes for more than an hour) to fill up their tanks.

The short answer is that unlike pretty much every other retail business that sells gasoline, Costco doesn't care about making money from its gas pumps. In fact, Costco typically sells its gas at a moderate loss. Why would Costco do this? It's not an act of charity.

Costco is mainly owned by institutional investors, who own over 70% of shares. The largest shareholders in December 2023 are: The Vanguard Group (9.10%) BlackRock (6.90%)

Does Costco have detergent gasoline? ›

Best Day of the Week

According to a GasBuddy petroleum analyst, Monday and Tuesday is when gas prices are typically at their cheapest. As the week goes on, prices steadily tend to rise while finally culminating in the highest price during the weekend.

Based on historical pricing data, the ACCC says the magic day of the week is Wednesday for buying cheaper petrol in Sydney, Melbourne, Brisbane, Adelaide and Perth.

If you are filling up in the middle of a hot day, the gasoline may expand, causing you to get less gasoline in your vehicle, which means you pay more for less. Filling up in the morning when it is cooler can help ensure the gasoline has contracted, and you get a larger amount of fuel for the same price.
