FAQs

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.

“You save approximately 20 cents a gallon at Costco over other local vendors,” says David Schwartz, who together with his wife Susan authored “The Joy of Costco”. “That's something we have seen time and time again across the country.”

So why is it so much cheaper than the competition? 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.

You save $3.36 per tank and $114.72 in gas per year in California.

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.

Is Costco fuel good? ›

It's just fuel from the same outlets as shell, BP and all the supermarkets. Fine to use.

Does Walmart water down their gas? Water and gas don't mix. They separate in the storage tanks with the gas on top.

If you're able to save $0.17 on 14.5 gallons of gas, each fill-up at Costco saves you around $2.47 compared with getting gas elsewhere. If you're looking to cover your membership fee with gas alone, you'd need to get gas at Costco between 24 and 25 times per year. If you go around twice a month, you'll easily do that.

THE ANSWER

Yes, it is worth getting a wholesale membership to save on gas prices.

An executive membership at Costco costs $120 per year, which is twice as much as a basic membership. The primary benefit of the executive membership is scoring 2% back on Costco purchases. Certain purchases don't qualify for cash back, including gas, stamps, and vehicles.

Plan your fueling around the quieter times, typically during the middle of the week and early in the morning. Additionally, members can consult the Costco app, which sometimes offers real-time updates on gas station wait times.

In general, gas prices tend to be lowest at the beginning of the week, on Monday and Tuesday, GasBuddy's lead petroleum analyst Patrick De Haan told Nexstar. As the week goes on, gas prices tend to rise until they reach their most expensive point on the weekend – especially on Friday and Saturday.
