Costco in Avondale (10000 W McDowell Rd)

Best price in the NW valley for the qualith

always plenty of gas, gas is Top Tier, restrooms are in the main building.

stations south on 99th Ave usually rival Costco for cost but have no lines

Members only of Costco can get gas here. Anticipate long lines. Gas is good quality.

Always a long line for fuel but often is the cheapest gas around.

Wish the lines were not that long 😰

Great prices!

is true prices

quickly service

Good clean safe station. Lots of room for traffic leading up to pumps. Have lights to let you know which pump is available. Nicely upgraded.
