The price of gas at Costco changes constantly by location and even by day, so there is no single nationwide price; you have to check your specific warehouse’s current rate.

Quick Scoop

Costco generally sells gasoline a bit cheaper than nearby name‑brand stations in the same area, often by several cents per gallon, which is why their gas lines are usually busy.

Recent snapshots online show Costco regular gas around the mid‑$2 to mid‑$3 per gallon range in some U.S. locations, with premium typically a bit higher, but these are just examples and not a guaranteed price for your area or today.

There are also websites that track Costco gas prices by state and warehouse (for example, pages listing current prices in California and nationwide averages), updated multiple times per day.

What Affects Costco Gas Price?

  • Overall U.S. average gas price trends (when the national average moves up or down, Costco usually moves in the same direction).
  • Local competition: nearby discount stations or club warehouses can push Costco to price more aggressively.
  • Wholesale fuel costs and regional taxes, which differ state to state and even city to city.

How To See Your Exact Price Today

To avoid outdated numbers, use one of these quick methods:

  1. Open Costco’s website or app, go to your local warehouse page, and look for the gas station info if it’s listed. (Some locations show pump prices or hours online.)
  1. Use a crowd‑sourced gas‑price app or site that tracks specific Costco stations; some third‑party pages aggregate current Costco prices by state and warehouse.
  1. Call your local Costco gas station or check the price sign when you arrive, which is the most authoritative source for that exact moment.

Forum & “Trending” Notes

  • Recent forum posts in early March 2026 mention Costco gas being noticeably cheaper than nearby stations in places like New Jersey and Southern California, sometimes enough to cause long lines at locations such as Wayne, NJ.
  • Social posts this month also show people highlighting premium gas at Costco in the mid‑$3 per gallon range in some areas, reflecting the broader U.S. average of just over $3 per gallon.

Bottom line: Costco gas is usually among the lowest‑priced options near you, but the only way to know how much gas is at Costco right now is to check your specific station the day you plan to fill up.
