The only place around that had oil when we were in a pinch. Amazing cashier and thankful for this place.

Great people and great prices. Clerk was super helpful and understanding. My goto spot in alpine for on the go snacks.

Usually much higher per gallon than anywhere else in the east county. Right now mid grade fuel $6.20 per gallon. Sycuan $5.50. Price gouging for living in Alpine residents. read more

I normally get my Gas here at Alpine Sinclair because it is a tad bit cheaper then their competitors. While I was pumping my gas, a young lady named Lauren approached me with a flyer of their Dino Car wash business. The car wash is located to the left side of Sinclair Gas pumps under a blue tarp. This week they are doing a soft opening of their car wash, so I thought let me give them some business. In order to pay for the wash you go to the cashier inside and pay there. Over all I'm a very satisfied with Bill and Laurens job washing my car, they took their time, my car looked great afterwards. They offer car wash, detail, and restoration services. They are officially opened on Friday 8/4/17. If you receive a flyer and bring it with you on their opening days they will take 5$ off of your purchase price and if you buy 5 car washes they will do 2 separate car washes for free. If your local or passing through and your vehicle needs some love don't hesitate to check this place out. Yeeaa I said it. Enjoy Yelpers!!! read more

Avoid at all costs, get your gas elsewhere. Not only will I never return here, I will never go to another Sinclair gas station anywhere, again. I just got done volunteering at a local animal sanctuary and was on my way home. I stopped in for gas. It has been rainy so things were muddy out. This is not unusual because this is the country, there's dirt and mud, people still ride their horses down Alpine Blvd., and so on. Before stepping inside I performed the common courtesy of wiping the mud off of my boots on the outside doormat. After several seconds of that the mud was off so I stepped inside and took the extra precaution of wiping my feet on the interior doormat just to assure they were also dry. Normally this would be called "doing the right thing" or "Thank God that boy was raised correctly." Unfortunately the lady behind the counter came unglued and ran over to me "You can't wipe your feet off on that! Look what you're doing to the rugs!" Well,... Yes, that's why they're there. They're the carpets that keep people from tracking dirt and mud into the store. Back when I was a kid and worked at my grandfather's convenience store we had slobs who walked in all the time without the courtesy of wiping their feet and tracking mud ( and sometimes tar ) all over the place. I'd have to clean it. At least there were doormats because you know, that's basically what they're there for. To make sure you don't track mud into the store. I'm using them for their manufactured and intended purpose. This lady starts arguing with me for about 20-30 seconds about how wrong I was for wiping my feet off on her precious carpets. Easy lady, these aren't Persian rugs and you're not in Persia anymore. These are DOORMATS! I got tired of her berating me and told her I'd never come back and spend any money with her or Sinclair every again. It would have been one matter altogether if I had just walked straight in and tracked mud all over but no, I had the common courtesy to wipe my feet off on both the outside rubber mat and the interior rubber doormat. Geez lady, what else did you want from me? When I was a kid and had to mop the floors of the family convenience store I would have killed to have someone show me that kind of courtesy instead of tracking mud all over. My advice: 1) Don't go to this Sinclair 2) Don't go to any Sinclair 3) But if for some reason you do have to go, track in a ton of mud and do it intentionally. God knows doing the "right thing" isn't appreciated at their store. read more

Best gas prices in town!! I know I'm getting quality fuel for my car every time I fill up. When I go in Sean is usually the one working, he's great!

First time using Sinclair gas. I saw the fuel dispenser said the gas is powered by Dinocare, so I asked the lady cashier, What is Dinocare"? She looked at me with disinterest, shrugged her shoulders with an unfriendly stare, and said, "just a logo". I said it has to be more than a logo..Maybe a fuel additive...She just stared and shrugged her shoulders..and said nothing. I said , oh I guess you do not know what dinocare is. She just stared at me....Very strange to have an employee like that..dies not care, not friendly, does not even know about the dinocare gasoline additive. I had to look it up online. May not return to this service station..too bad. No phone number or email address on my receipt to inform managenwnt. read more

Be careful, if you use your debit card to get gas they automatically put a $200 hold on your account, so if you have less than that in your account say $125, like I did and only got $40 worth of gas, my bank like most will then transfer $75 from your savings account to checking to make up the difference and charge you $5.00 for the transfer fee. If I buy $40 worth of gas put a hold on $40, not $200. Sorry, but not a place I will buy gas anymore! read more

Nice gentleman inside, but worst my car has ever run. I filled up on 9/4/16. I purposely never went to the 76 that previously occupied this lot but I thought I would try Sinclair out. Bad idea. I purchased medium grade gasoline and since, my car has not been accelerating well in any gear. Never had this happen before. I usually get gas at the Mobil in Lake Jennjngs. I can't wait until this gas is out of my car. I am never going back to Sinclair. read more
