Service - Self service. Price - $5.33 a gallon, 4 cents more than our San Leandro Costco that we frequent often. Worth the extra 4 cents to avoid the mess in the SL location. Glad we filled up!

I just went in there tonight and bought a gallon of milk and it was $9.99. WTH!…read more That is sure craziness! How do they get away with that one!?!? Isn't milk regulated? The damn cows must be on strike. Yeah, I won't be going back in there for milk or anything else now! The worst part about all of this is reading the reviews of people complaining about the ones that work there the customer service and everything going on, and there has been no replies at all from whoever owns this store or manages it. I've been in there a few times, just buying lottery tickets and they look at you like oh God what are you doing? As if I'm inconveniencing them to do their job. I have worked in retail, my whole life, and I have never experienced the price of milk for one, and then some of the clerks that work there you really need to consider getting new people. How about we get replies to some of these reviews! Most businesses see a review on yelp and they don't like negative reviews. I'm guessing it's a gas station so they don't give two shits they know people will buy gas! And dumb people like me but I was on a time limit to buy a gallon of milk. So that's my bad I should've walked out and went around the corner to Safeway down the street would've been easier and better. I will not make the same mistake twice!! I attached some information photos, just for FYI

I forgot to post this review last week as I was headed back to Red Bluff from the Bay Area. I…read moreneeded gas and usually I'd stop at the Costco gas station cause of the cheapest prices, but no way I wanna wait in long lines in the middle of the day. Fast on and off the 80 freeway is what I needed. Plus Chevron always has a nice little store, clean restrooms and mostly has what Costco gas lacks, windshield cleaning supplies and squeegees. Windshield is a mess after leaving it parked for almost a week while I went on field location work sites. Just pulled off at the 505 freeway exit and took the first exit instead of going on to the 505. You can see the Chevron station right there. Pulled in and used the credit card no prob. The card readers work perfect, none of this multiple tries like some of those cheaper off brand sketch stations. There's even a car wash here if you need that. Pop Eye's fried chicken is next door if fried chicken is what you need! Gas pump work perfect and no spilled gas. I got my windshield all cleaned, wow that makes a difference! OK, I'm outta here and back onto the 505 headed north. Prices aren't the cheapest, but worth it for the nicer station and full service store. Yeah, I got some Coke and Funyons for the road!

Didn't like b20 diesel, tap credit card didn't work and receipt didn't print at the pump. Inside…read morewas clean - the store - and person at cashier was friendly. I often drive to Elk Grove/ Laguna West and sometimes stop here for gas. Usually its ok but this last visit was a little worse than normal - I think because I was in my CDI Mercedes diesel. They serve b20 here - and for those that don't know what that means - its a bio diesel blend that is 20% bio - that stuff is usually very very cheap - and the fuel here was $1 more expensive than a diesel #2 spot that was just 20 miles further down the road. Believe it or not I don't drive my CDI all that much... maybe 1000 or 2000 miles a year - I just have more interesting cars to drive. I love my CDI and it gets 45 miles per gallon and in style and comfort - but usually it just sits in the driveway. Because of that I really have concern for the type of fuel that sits for a year at a time - I as I can get nearly 1000 miles out of a tank - that means my fuel sits for a year before I refuel. Bio tends to grow slime and ruins the fuel system - I don't like that. I suppose the worst part is they charge top dollar for what I believe to be worse quality than diesel #2. Bio does have the benefit of great lubricity - so if you go through your tanks fast and use anti gel in the winter b20 should be fine. I prefer hot shots everyday additive and diesel #2 - trust me I did the research - you might want to look into it yourself.

Had to…read morereturn an item, took a while because there were only 2 people working the customer service desk. Eventually after the line behind me got longer, they brought over 2 more people to help out...total wait time was about 10 minutes. Walking around, I noticed they are really stepping up the Asian inspired food items! They still have some discontinued summer items to make room for the winter holiday season. I picked up a Henckels BQQ Grill Basket/Topper with 6 Skewers for $4.97 (only about 5-6 left)! They had quite a few food sampling stations this Friday afternoon. Checkout moved well at the self checkout.

The hot dogs remain unbeatable, obviously, but it's more than that. Gas here is consistently cheap compared to nearby options, which adds up fast if you're a regular. Between the deals, the gas prices, and the classic hot dog combo, this is one of those spots that just delivers every time without fail. Love this place, and it's earned its spot as a regular stop for me.

Diesel #2 I prefer to biodiesel and liked that I saw it here. Pump areas were clean and a receipt printed at the pump. Disposable gloves were a nice touch - unusual but shows extra care. I paid about a dollar more per gallon than the cheapest stations where you pay cash. So 4 stars for value and overall experience.

The hubs started pumping, then went to the bathroom while I sat in the car. When he came back, it was at one gallon. I decided to go into the convenience store and grab some snacks. I walked around for a bit since I couldn't decide what I wanted. Ended up getting a bag of cheetos and two meat sticks for a little less that $10. When I came back out, the pump was at something like 5 gallons. I think it had been like 10 mins already. Maybe even 15 mins. If you are in a hurry, do not come here. It'll take like 30 mins to fill up your tank. REVIEW #3499
