Well, this list has you covered and will not only tell you what Costco gas stations have the best reputations, but also the best times to go.

This Costco gas station got its 4.6 star rating from consistently supplying drivers with accessible, affordable, and fast-moving service.
"Quite busy at the entrance, occasionally with traffic backed out to the main road. It's very convenient that the hoses are long enough to reach across the vehicle so you can pick the shortest line no matter what side your gas cap is on," reads a review.
"The service attend[ants] are friendly if you need assistance," added another user.
The least busy times to go:
- Monday to Friday: 6:00 a.m. to 3:00 p.m.

Reviewers gave this gas station a 4.6 as well for running a smooth operation that is both quick and cheap.
"Came here for a quick full tank before we hit the highway. Good place — not too [far] off the 401. We were in and out in no time. It can get busy during peak hours, especially [on] weekend morning[s] but it was still smooth and quick. Definitely recommended," wrote one reviewer.
"Ever since they added more pumps, the waits are so much shorter. Still wild busy but usually the cheapest around by a few cents. Over the course of the year, the membership cost is made up in the price of gas alone," added someone else.
The least busy times to go:
- Monday to Sunday: 6:00 a.m. to 9:00 a.m.

With a 4.5 rating, this spot has the savings you want, but by the sounds of it, the lineups are no joke.
"Always a better price for gas. The location/lineup layout is not ideal because it's a sharp right turn once you turn in from the road and it causes a bit of a roadblock. Try to go at off-peak hours," wrote one user.
"Timing to fill up is important to avoid the long lines," commented another customer.

This bustling station can be a bit tricky to navigate, but if you've got 10 to 15 minutes to spare, its superior deals on gas could be worth the wait.
It ranked 4.5 stars on Google Reviews, which isn't bad at all.
"Entrance to this place is a bit tricky because the lineup starts through the Costco parking lot and people try to cut you off when they turn in from the stop sign," reads a review.
"Probably the closest Costco gas station if you're in Mississauga area. Decent one. Although during busy hours it can be crazy since there is a small queue space, so the queue can spill over to the main road or the parking lot. Having said that, with three pumps per queue, the turnaround is fast," reviewed someone else.
The least busy times to go:
- Monday to Friday: 6:00 a.m. to 3:00 p.m.
- Saturday and Sunday: 6:00 a.m. to 9:00 a.m.

This gas station gets its 4.5 star ranking for having some of the cheapest gas prices in the area. However, some reviews suggest that the service could be better.
"Typically the best price in the area, the only downside is the wait time and dealing with incompetent drivers who aren't paying attention in the lineup. Perhaps a little more guidance from Costco staff," one user wrote.
"Busy! but be patient, it all works out. Attendants could help more in directing cars instead of standing around while customers figure things out on their own," read another review.
The least busy times to go:
- Monday to Friday: 6:00 a.m. to 10:00 a.m.
- Saturday and Sunday: 6:00 a.m. to 12:00 p.m.

This Costco gas station got a 4.5 star ranking on Google Reviews, however, timing will be key for anyone planning to take advantage of this station's cheap gas, which is best suited for early risers.
Always great with price, but [the] lineup [could] be smaller if only they upgraded to four gas stations per line," a commenter wrote.
"Cheapest gas in town. One less star, for the chaos that happens when there is a line up," another added.
The least busy times to go:
- Monday to Friday: 6:00 a.m. to 12:00 p.m.
- Saturday and Sunday: 6:00 a.m. to 9:00 a.m.

This Costco gas station's long wait times factored into its 4.4-star ranking and place on this list. Although, the most recent reviews suggest some issues are being addressed.
"New and improved pumps. Now 24 spots. Less waiting. Good improvement, if only people would move up," one user pointed out.
"They recently added a third pump on each service island. The lines [are] now shorter and faster," wrote another.
There were no busy times listed on Google Reviews for this location. However, several reviewers noted that going after 5:00 p.m. on a weekday or during the day on the weekend can get hectic.

Despite being at the bottom of the bunch, this Costco gas station still has 4.2 star ranking on Google. So, you if live nearby and need to fuel up, definitely hit it up.
But, when deciding whether to fuel up at this location, you must ask yourself, "Is it worth the hassle?" At least, that's what scrolling through its Google Reviews would appear to suggest.
"There can be lineups at 6:00 a.m., but the gas is much lower than any other station, and it’s top tier. Drivers can be quite dangerous trying to get in line as fast as they can, so be careful! If you’re parking or walking in the parking lot, be extra careful, since cars will literally whiz through any space between parked cars, to avoid the speed bumps!" warned one user.
"Hopeless place. There's always a huge queue. Wastes at least half an hour each visit," added another.
The least busy times to go:
- Monday to Friday: 6:00 a.m. to 8:00 a.m.
