Unfortunately this location has not been remodeled like some of the other locations with additional pump stations. Lines can be very long and slow lol! On the upside it is conveniently right of the 10 fwy exit / entrance. Today's gas is $4.19 9/27/2025 read more

Great gas, lines are usually pretty long but there's lots of pumps and lines usually move pretty fast. Gas is cheaper than most places as well. read more

7/8/24 Always reliable. Every morning a few cars (about a dozen or so) line up just before it opens up & like clockwork, the Costco attendant lets the customers in by 5:30 am. Nice, neat & orderly, everyone fuels up like a ceremony without incident. Reliable & the prices are almost always competitive. read more

Filling up the rental car on the way to Ontario International Airport in Los Angeles, California... Looking at a map, I saw that this Costco Gasoline station was nearby and might be less crowded... There are two pumps per lane... there were many lanes and not enough time to count because everyone moved along smoothly! Just look for the signs for the traffic directions (there was a small arrow) and follow cars ahead... It will all work out! Thank you for the convenience and lower gasoline prices! read more

The lowest price gas. You just have to be patient cause depending on what time you go it can be a 15min wait. I like that it is one way in and one way out so you don't have to worry about anyone cutting you off from the opposite side. read more

I love Costco gasoline prices. This Costco is on my way home from work and not my local Costco gas station. Once in a great while I forget to fill up and I'm forced to fill up here on the way home. Unfortunately they have not upgraded their pumps like my local Costco. Each lane is still 2 pumps per lane where the updated Costco gas has 4 pumps per lane, which makes the lines longer. Forces me to remember to fill up at my local Costco. lol Otherwise price is still good Costco price. read more

Came on a Saturday late morning. Costco always has the best gas prices. Typical Costco gas station format, except this particularly station only has 2 filing stations per line/column so it's a bit slower, but as a regular of Alhambra and MP Costco, this one wasn't as crowded so the lines moved quickly. read more

Great value! Can't beat Costco gas prices. This location is right off the 10 fwy so it's convenient. I usually stop by early before work. They set up cones to easily guide traffic in and out. Very efficient. read more

Anyone else appreciate this exclusive club of bulk savings on gas? I know I do. It's located off the freeway and you end up saving a few bills with each fill. Perhaps not the easiest Costco Gasoline to navigate or one with the most pumps and sure there may be a little chaos in the lines from time to time, but that's the thrill of a deal. It's expected. You're getting good quality gas at a great value. read more

Costco Gasoline - Prices - Gas Stations Near Me - Montclair, California

As I said before, this is my go-to Costco gas when I'm in Montclair. Line can get really really long where cars may be lined up all the way out to the entrance just like yesterday LOL. I think they should relocate the gas stations to the back of the parking lot instead of the front for better traffic flow IMHO. Unfortunately, the only gripe is the long line and long wait time that goes with it. Patience is key! Costco gas prices are normally lower than the name brand gas stations. So glad they put back the trash can bins. Trash is usually cleared out timely... never see overflowing bins. Attendants are always available to assist with anything and provide the service requested. The other thing I like about Costco gas besides their price is being able to pull the pump to the other side of the car... it allows some flexibility... you can use both sides of the pump. Thank you Costco Gas! read more

Be patient there are only 2 pumps per island but the hose is long enough to reach the other side read more

Costco Gasoline - Today's gas price. Regular - Gas Stations Near Me - Montclair, California

Great price. About 5-10 min wait on average, but worth it compared to other gas stations in the area. Note: You have to get in line for gas in the back of the Costco biulding. There are signs. read more

When I pulled up to the pump with my almost empty 75 gallon RV I was a bit surprised to see that Premium was the only option. I noticed the price was similar to what I had paid the day previous for regular unleaded in my car. I asked the attendant about it. His response made me a customer for a very long time. Attendant stated yeah - premium is being charged at regular rate. It's not your fault we don't have regular. That's the way to do business!!!! read more

The gas here is at least $.29 cheaper here as opposed to Chino hills location! No line on rainy day when I showed up Saturday evening.

Gas is cheaper than most places up in the high desert and lines go pretty quickly. Plus you can get your car washed right after for only $8

Lines are never long. This gas station is very convenient. Only thing is that this is a smaller one from others that I normally go to.

Always a good deal, but the wait is long! I mean I guess we cant do anything about it. Staff is helpful read more

Lines are always long. If you get here at 6am not so much. But excellent prices. The service attendants are always helpful. Quality of gas is good. read more

One of the busiest Costco Gas locations I have been to. Came on a random Friday morning and it was crazy packed. Older gas station set up, they only have 2 pumps per lane. Line moves super slow. read more

Was able to get in and out quickly. Didn't see any self check outs. That's helpful when you don't have too many items. The set up For gas is kind of a mess. Lines get ridiculous here. Customer service is awesome though read more

Best top tier gas and best prices you'll find anywhere! The line may seem long but they move really fast just know you must have a Costco membership in order to purchase gas here. With the gas prices of today, you simply can't go wrong here! Oh and only 87 and 91 gas available read more

I think the gas prices are cheaper here. I save at least 10 - 15 cents per gallon. Sometimes even more depending on the time. You must have a COSTCO card to use the gas pump. Service is great and the supervisors here are Ok. However, sometimes the lines to get some gas are long. Getting there early I the morning g beats the crowd and it's quick. read more

This costco gas has 16 pumps, best prices in the city. Only thing are the long lines They recently conned off the main entrance (why?!) So now you have to go all the way around to get to the gas station area. Visa only accepted. read more

The turn here is a little awkward to get into the Costco Gasoline on busy days, and it seems in LA/San Bernardino County, the only place to get Gasoline practically is Costco Gasoline due to the enormous cost savings over their gas competitors. Came here on a Sunday afternoon and just to turn into the Costco complex (read, NOT Costco Gasoline yet) was a pain in the ass. By the time I could get to the Costco Gasoline area, that area was completely packed full of cars, so I had to wait about 2 minutes before I could even get to a single line. Thing is, time is precious with the California lifestyle. So for those of you that hate long wait times, you may want to either come earlier in the morning or later at night right before they close (check Costco's main website to get the latest, most accurate hours of operation). Other than that, it is what it is. It's a gas station that sells cheap gas. Membership is required, easiest way to get membership is to walk into the Costco warehouse attached to any Costco Gasoline location. BTW, check Groupon every now and then. Sometimes Costco has a membership discount like save 20-30% off the normal price for membership, or something to that effect. YMMV. Side note: There is a "mobile payments" logo next to each fuel terminal but every time I go to a Costco Gasoline to test my Android Pay, it doesn't work. I've tried to ask Costco via their Twitter but never get a response.. read more

Best prices. Whether it is quality gas is another question. Best to come during off hours otherwise the wait time is quite long. It is common practice for people to turn off their engines to save gas during waits. read more

Costco Gasoline - Gas Stations Near Me - Montclair, California

Good gas station with lots of lanes. Like most Costcos the hoses are long enough to reach gas caps in either side of a car. Entry and egress are poor due to the proximity to Central Avenue. Always go to the gas station before you go shopping at Costco. Access to the gas station from inside the parking lot is horrible. Four stars overall. They lose a star because of the poor access. read more

+ Cheap gas prices - Only one entrance - A lot of pumps but only 2-deep which means it takes a while to get in and out The two times I have been here in at lunch hour, it takes about 15-20 minutes to wait in line and get gas. It's hard to do on an hour lunch break. read more

Why in the World, don't have a Sign on the Gas Station of the price of Gasoline that day? It really amazes me. read more

Costco Gasoline - Who da fuck comes with a Bike to put gas ? Is like 10 gallon tank, God damn Trump supporters - Gas Stations Near Me - Montclair, California

There is a short man with a mask and a Costco vest on. He keeps telling drivers to go to different lanes to get gasoline. For some reason he always allows drivers behind me to get ahead of me by going into shorter lanes. I don't understand his logic other than he's a dumb ass! I won't be coming here anymore. Might even cancel the membership. read more

Expect long lines especially during peak hours. Fortunately, I live nearby and can fill up my vehicles early when they open at 6:30 am. Can't beat Costco's fuel price. read more

47. Gas is so expensive nowadays. And not all Costco locations have the best prices. But I always come here to get gas because this Costco consistently has one of the lowest prices in the area. It might be quite a wait though, depending on when you're here. Sad fact: Can you believe that gas prices averaged $2 a gallon in early 2009? And three years later... gosh, I miss those days. read more

Great location (right off the 10) and best gas prices. Usually can't beat the prices here. Must be a Costco member. Long lines, but worth the wait if you have the time! If you're looking to compare gas prices, try downloading the app GasBuddy. Helps you compare gas by location and prices. read more

1 Negative was overturned with TWO positives by the AMAZING MEL (manager) & TYLER! Briefly, my negative experience was soon rectified by the two young ladies at their location. Called in earlier before driving to this location. Drive would take a bit over 30 minutes due to being further away in this terrible rain. Spoke to Ericka whom confirmed item was available in stock and guaranteed by since she checking on hand stock. Didn't see bags needed for dog food in aisle so went to the front were I was assisted (somewhat) by a supervisor in a red vest. He checked inventory and other PC, immediately said we don't have, we sold out and tried to ignore my request of how I was advised by Ericka that inventory was on site. He practically did everything to avoid this conversation. Even used the, "I'm already leaving card". When I realized his body language and his actions where to not assist, I called from same section and was assisted my Mel. After we got disconnected, she came out and greeted me, checked inventory and dispatched one of her crews to locate product that was found sitting on the dock but in inventory. She was able to have bags brought up, purchased and rectified her crew negative interaction. Mel (manager) was very positive and motivated to assist and make a name not only for herself but the company in which she represents. Tyler (check out agent) at exit door was very kind and pleasant to work with. She was even very kind to watch my cart with supplies while I ran to get my truck since the rain storm had just hit. Thank you Mel and Tyler for being a fantastic, wonderful part of your company. Please continue the excellent work you are doing and alI sincerely hope your Compnay recognizes your exceptional service. Thank you the both of you!!!! Mel Taylor read more

Not a bad deal for gas. You have to be a Costco member. At the pump they take ATM or American Express I believe. The only down fall is the lines they have during the rush hours as well as the weekends. But worth the wait if you have the a little time to spare out of your day, or if you drive a larger SUV that holds 25 to 30 gallons pls of fuel. read more

For some reason I'm trying to write a review on this Costco location, Montclair and its Costco Gasoline! Nevertheless my review of this Costco location, and food court is terrible! My family absolutely look forward to shopping and afterwards who can resist not stopping by the food court! Exactly. Hands down everyone stops to purchase food especially hotdogs or pizza. I'm very, very, very, unhappy and was disgusted with their pizza. It was straight up NASTY I don't like Dominos pizza but we maybe should've ordered from the "D" Costco get it together.!!!! This location is not managed well obviously I'm a native of Inglewood, Ca and Costco in the SB is popping! So Montclair get it together read more

Just the standard Costco gasoline. Lines are quite long on the weekends. So plan accordingly. No complaints. The long lines are to be expected. Lines aren't too bad here. Been here several time. People usually don't take too long. They get in and get out. Reliable service. Employees attentive and seem helpful (from what I've seen with other people, I haven't had any personal experience with them) read more
