Costco in Thornton (16375 Washington St)

usually no lines, way in the back of pushing lot...near floor n decor

Excellent gas station and awesome prices!

Seems to always have a fairly decent $ on gas. The new pump handles are a little tricky to use~Can be busy at times for the most part though people are courteous!

Excellent!

one of the best fuel prices in the area

great place !

Great place.

Would be hard to find a cleaner and well lit station.

Well maintained as all Costco gas stations are.

Costco does a great job keeping the pumps clean and surrounding area clean. Attendants are friendly and attentive. Prices are always competitive and typically lower.
