Diamond Bar Shell & Mini Mart

The service here is horrible. Put gas in one day and had to go inside to pay with cashier. Rudest person I’ve ever met! So condescending for no reason. Now I never go here.

I used to LOVE this place! Tony is awesome once you get to know him. He’s actually a great guy, but can seem like he’s a jerk, or rude if you don’t know him.
Recently there was a change of ownership. A few of the changes I’ve noticed so far are no more carwash cards. The second was them raising the prices on the Monster’s and Rock Star’s! WTF??? They are now 2 for $ 4, without changing any of the signs!
I will not be going back anymore, I can go to most other places and still get 2 for $ 3 energy drinks. Yes, this is a HUGE deal for me and a deal breaker! This is only because work a lot of 16 hour days and they keep me going sometimes!

Worse customer service manager there is rude to paying customers by far the worse shell gas station I have ever been to rick the manager gives shell a bad name with his fowl mouth and rude commits

Rude rude rude, Tony a manager or owner decided to Immidiately upon me walking in was going to disrespect me you can hear it in his tone, he forgot the business he’s in, people business! He lacks every single ability to communicate with customers who’ve come here to do what wants them to do buy. Buy from him not his competers… keep it up Tony, customers don’t like being disrespected specially when their the reason you are employed!
Absolutely no Stars!!!

The people here are rude!!! I’m actually a frequent customer here (not anymore though after tonight) along with the rest of my family and friends. I would often get gas here and a car wash and pick up some snacks at their mini mart. I got off work this evening and needed to pick up some quick snacks and intended on purchasing a car wash; as I pulled into the parking space right outside the mart, I received a business call that required me to stay in the car for a few minutes to complete. Next thing you know I have some old Korean guy storming out the mart pointing and screaming at me from outside my car saying «you go away! Over here parking only 5 minutes! Go!» Well then I guess I just won’t buy that car wash and those snacks then after I complete my call and I won’t ever come back (I will also make sure my friends and family don’t ever give them business again)! It’s sad to say but it’s rude and ridiculous Asian business owners like this old man that give a bad name to other Asian businesses. It’s fucken 10pm, there are spaces to my right and left opened, I’m not blocking them from gaining more business and I’m in a parking spot not blocking a gas pump wtf!

These people are rude and crooks.
I stopped by for corn dog couple times already, and each time they charge me different prices. The sign clearly says 69 cents, one time I got charged $ 1, another’s time $ 1.69, one time $ 0.85. When I confronted them, they pretend they don’t know English.

$ 4 car washes. Although I tend to get the top tier carwash. At $ 7, you can’t beat it.
As far as the employees, they’re great. I love the guy with the gray hair pomp and the guy with the pony tail. They always let me in late night to get munchies and they put up with my indecisiveness when picking out candy.
The selection is not bad. They were first to get hostess when it came back. That was a plus. Kazoozles, grandma cookies, and lottery tickets. That’s all I need from here!
I never come here to get gas. It’s always ten cents cheaper across the street at arco.

False advertisement, sign says $ 3.59 at the pump $ 3.63. Bait and switch. Wasn’t even using credit cards

I just called and they said that they could not give their gas price when I was comparing prices. Don’t they want our business? 11÷30÷13 11:15AM

I come here for car washes only.
$ 4 for a basic, no frills, machine car wash.
It’s open ²⁴⁄₇.
Get’s the job done at an affordable price.
Oh! Don’t forget to get the stamp card. Once you accumulate 5 washes, you get a premium wash for free.

There’s not much to say about this gas station, or any gas station for that matter. These days I just pay at the pump, rarely going inside. The station itself was clean, albeit a little crowded. It’s easy to get in and out of, but the pumps are close together making it tough if there’s someone in front of or behind you.

The gas here is usually pretty competitively priced. Also they do not do the bait-​and-​switch cash vs. credit card pricing as I have seen at some gas stations with their signs displaying their prices. They have a decent mini-​mart and a drive through car wash. Very conveniently located next to the 57 freeway.

Shell has lowered prices but regular gas for 3.89 is for cash pay today at Walnut. Though checking the LA area the lowest gas price is at 3.69. That means Shell is charging 20 – 30 cents extra profit per gallon no wonder their earnings are sky rocketing.
To get a better deal go early in the morning for a fill up you get cold compressed gasoline and vapor loss is less. Pump slowly to reduce vapor loss and you save more. Check the pressure in your tires at least 35 psi for good mileage. If you push in more air the ride becomes noisy and rough.
Tell all your political leaders to reduce gasoline prices.

This station sucks! It’s not worth the few cents per gallon to put up with the jerks in the station.
Everytime I go to the station the letch behind the counter clicks off the pump just to get me to walk into the store.
I called Shell. They said there is nothing they can do about sexual or racial discrimination. So I buy my gas at other stations and I highly recommend that you don’t buy Shell gas at this station either.

Haven’t been in this place for a long time, decided to check it out because it was in the area. After a few years the size has remained reasonable; not a super store by any means, but definitely not lacking.
While perusing through shelves of inventory, I was specifically looking for an energy drink or health drink. To my surprise, just to the left of the register was a section of cheap energy drinks and health drinks. Also coupled with sandwiches, with what seemed to be like ham and turkey.
The beer selection is not as extensive for my liking, though that isn’t necessary. As the shelves are plenty stocked with viable alternatives to browse about.
Food selection is okay, mainly limited by size. If it’s any reason I prefer this place to another is the quality of the staff that has worked there over the years.
Great quick stop place, where you may not find everything, but near close to it.

I like the people that work here. Super friendly people and its close by. Keep up the good work guys

LOVE this place ! Its cheap, in a good area, never packed, and clean. nuff said.

Go across the street to the Arco. it is always cheaper.

I don’t normally review gas stations or convenience stores, but this is my favorite gas station/​convenience store! I’m usually here in the mornings to fill up or pick up something on the go. Sometimes, I come here after work to pick up snacks, put air in my tires, and chat with the fellas who work there. The people who work here are REALLY friendly.
Note: Gas is actually reasonably priced here compared to other locations (excluding cheap gas like Arco) around the 3 mile radius.

something about their v-​power entices me to stick with shell. my vw beetle seems to have an extra oomph of energy with v-​power (i swear i can feel it with 4+ dollars/​gallon in my tank) or maybe i’m just disillusioned…
this shell is by far the cheapest gas around my neighborhood. located right off the 57 fwy at brea canyon rd. exit, you can roll off the freeway and get some gas and roll on the freeway again! or go elsewhere…
i’ve used their automatic car wash service before. cheapest quality EVER. you know how you go to those automatic car washes to anticipate bubbles in the colors of the rainbow covering your car? well, you get watered down soap that you can still see through your windows after they’ve sprayed ya. lame. my car came out still looking like it hasn’t been washed. i’m going to refrain from the ethnicity that owns this gas station. i will be at fault for ratting out people of similar kind.
lesson learned: go for gas. don’t go for car wash.
