7 Reasons to Fuel Up at Costco Gas Stations
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.
Check out these seven reasons to use the Costco Gas Station:

Plus, lanes are all one-way to keep traffic moving.
