Wide lanes makes it easy for big car and small car drivers alike to navigate through. This Costco gas station is also located next to a Costco Business Center (so not your regular type of Costco) - which helps I think with the smaller crowd. There was no wait at the time I stopped by (a little after 7am on a Sunday). Prices as usual is always great - $5.39 for premium at the time of this review. No issues with the pump other than it not reading my mobile app membership QR code, but luckily, I had my backup card with me. The service attendant was present keeping things tidy. As I found out during my recent stay - there's also a Starbucks and yummy poke bowl spot in the same shopping center.

Wide lanes so that you can navigate around other cars to get to an open spot and even on a Sunday afternoon, there was no line to get gas with so many pumps available. Costco has always been known to have really affordable, cheap, but not watered down gas, so it's a god send for people who are members. I honestly think my only issues were that it didn't take the app version of our membership no matter which pump we tried and we had to talk to a team member to manual activate the pump and get our membership ID number. Also, the Internet connection near every Costco is infamously awful, so there's that too.

It's…read morean excellent place to get all your basic necessities if you can't make it to other nearby convenience stores that require driving. The must-try dish here is the chicken spot! Who would have thought that a gasoline station's mini-mart fried chicken would be so popular? Every time I come here for some chicken, there is always a line, which is a testament to how delicious it is. Chicken orders come with hot sauce or ketchup. The staff consistently makes fresh batches, but sometimes, if there are larger orders, you may have to wait a bit. During my hotel stay, I make a quick stop at this place for basic necessities like Gatorade, water, snacks, wipes, gum, and sometimes even gas. I have seen this station become a little full, so be patient. Lastly, I like that there's a gate that leads to the cul-de-sac where the hotel is.

MEDIUM-SIZED GAS STATION OFF 10 Freeway...I came by for some gas as I was on my way to a Yelp event…read moreand this gas station was right off the freeway. It's a little hard to enter as there's a divider on Shelby that prevents you from making a left turn into the premises. The Mobil has great vibes, I loved the music they were playing and people seemed to be in a good mood. I was rocking out to Scandal's "The Warrior" while I was pumping gas, it was fun! The gas station was pretty clean and I was easily able to find a slot to refuel. The gas lasted me for a while and was relatively cheap compared to Chevron. I trust Mobil's gas quality as it's lately been my go-to. I didn't request any other services other than acquiring gasoline. The Mobil is near Ontario's hotel hub and some eateries, if you're taking a road trip or just hanging around, I'd recommend coming here. I didn't run into any staff on this visit. I would request they add more parking space for customers who are not buying gas.

I had get on the 10 freeway and drive to 4th Street to the Shell gas station there to add more gas and that's when I noticed the dial moved up. Not sure what was going on here, but it did make me rethink going here as a last resort. I'd rather go down 4th Street to the Shell gas station by the 10 freeway entrance.

I was sad there were a couple things missing like hot dogs, heated food, and crushed ice. Gas prices are decent for an Arco. The station is a good size so you can get a lot of sweet treats and canned/bottled drinks. You can also get cases of water and other items if you're staying in the hotel hub here in Ontario or heading to an event. The fountain drinks weren't watered down and were well-filled. The quality of service was a bit gruff but no one was rude.

When I gas up mid day on weekdays I have not had trouble getting a pump like some other reviewers complained. Further, and contrary to other reviewers, and similar to other Arco's the cashiers here have been polite enough when I just buy gas. Like other Arcos it is actually some of the customers who are not nice. They will fight for you for the pumps they want and dangerously cut you off. This may be due in part to the fact that their pumps do not extend like at other locations and so you need to get the pump that is on the side of your car with the gas cap. Of course that is no excuse for some people's behavior, just a possible reason and something to keep in mind when filling up here. Additionally, and like many other Arcos, there is usually at least one homeless person lurking near the pumps, but none have aggressively approached me at this location so far as they do at other places. Based on other customer's reviews, I would recommend not making purchases here other than gas in order to avoid problems with the cashier. There is a Target right near by and you can get the same items there for a cheaper price. So save yourself the potential hassel at Arco and just get gas here and get items at Target.
