Why Is Costco Gas Cheaper?
Costco, like Sam's Club, uses low gas prices as a traffic driver. Members who stop to fill up are more likely to walk inside and spend money. Costco buys fuel in bulk from refineries and major suppliers, passing those volume discounts to members. They also run their own tanker fleet in some regions, cutting out distribution middlemen.

Costco Gas — Frequently Asked Questions
Do you need a Costco membership to buy gas?
Yes. A valid Costco membership is required at all Costco fuel stations. The Gold Star membership is $65/year; Executive is $130/year and includes 2% cashback on most Costco purchases.
How much cheaper is Costco gas vs the national average?
Costco gas typically runs 15–30¢ per gallon below the national average — making it consistently one of the cheapest gas sources in the US. Some members report savings of 40¢+ in areas where local prices are unusually high.
Why are Costco gas lines so long?
Because the price is genuinely lower. A 20-cent savings on a 15-gallon fill-up is $3.00 — worth a few extra minutes for most drivers. Costco stations also tend to have fewer pumps relative to demand. Lines move faster than they look since Costco pumps are typically high-flow.
What payment methods does Costco accept for gas?
Costco accepts Visa credit cards, Visa debit cards, cash, and Costco Shop Cards at the pump. They do NOT accept Mastercard, American Express, or Discover.
Is Costco or Sam's Club gas cheaper?
It depends on location, but Costco gas tends to be slightly cheaper than Sam's Club on average — saving 15–30¢/gal vs Sam's 10–25¢/gal below the national average. Both are significantly cheaper than branded stations (Shell, BP, Chevron). Your best bet is to check the app for each before filling up.
