Always friendly and helpful staff. Cheap prices and free water bottle if you spend more than $40. I always come here.

Best prices in town by far. Independently owned and operated. I like to frequent businesses that are like this as I'm also a small business owner in the area. read more

The guy that works here is so nice! I bought oil and he even offered to help me put it in my car, no one has offered to help and he gave me a funnel. He also noticed my dog was in the car, with the AC running of course, and gave me a treat for him. Thank you so much for being so friendly and offering to help! read more

Hands down ( with a free plastic glove) the.BEST.gas.station in San Diego. My go to family owned and operated business. Best price, an offered piece of fruit or cold bottle of water; what other fueling station does that? Extremely friendly, clean, and stocked with snacks, beverages, and free books. Please support this local business. We need them to survive and thrive. read more

Propane Rip-Off !!!. You live and learn. I ran over to my local gas station where propane costs $3.19 per gallon INCLUDING tax. Their pump wasn't working, so went up to Emerald Gas Station where I figured the cost would be slightly less than my brand name gas station because they tout low prices for gas. WRONG !! Emerald charged me $4.59 per gallon PLUS tax. I had the food on the grill, so I had to bite the bullet. Cost me just short of $22 for 4.4 gallons. WHAT A RIP OFF. I won't be patronizing Emerald Gas again. For anything.... Regarding the coupon and exchange. Most 5 gallon tanks have over half a gallon of propane in them when they register as empty. When you exchange propane bottles at Emerald Gas, you pay for 5 gallons, and in exchange you gave them a 1/2 gallon that they gave you no credit for. BUYER BEWARE read more

This gas station has very convenient location by the freeway and a low gasoline price and propane exchange very friendly staff and great selection of drinks and snacks keep the good work read more

I feel that this is definitely the place to go for gas in La Mesa. Very cheap gas, when the oil companies aren't being too greedy, they give away free things sometimes and I feel like they care, well as much as a gas station would care. Of course before I came here I looked on old yelp to see what others had to say about this place and most of was good. So it lead me here and I'm very happy that I did. This will be my Gas Station of Choice for as long as I live in La Mesa. read more

+1 for everything Dylan said in his review below. If this station is convenient to you, go and check it out. The people are nice, and I like how they have all these clever "no smoking" signs around the place. (I can't remember exactly what they say, so you'll have to go down and see for yourself!) They're always cheaper than anyone else in the neighborhood, and they take debit (just not credit). read more

RIP OFF!!!! Gas Buddies says the Cash price - ok. that's fine. i get that. Sign at the street says 14 CENTS MORE for credit!! REALLY? 14 CENTS?? That's CRAZY!! Pump is unclear as to if you use credit or debit if you have to pay the 50¢ card fee ALSO in addition to the high price or what. Or was the 50¢ just for debit and you get the cash price. or what. AND THEN, wait for it, the pump price was MORE than the sign said! by 5¢ per gallon! I was pissed! I put $5 in and left. what a rip off! read more

This is one of those places that you have to spend a certain amount if you use your bank/credit card, which always makes people unhappy. The people are nice, and helpful. The best part is they have some of the cheapest gas I have seen in San Diego, and they offer propane refill. read more

Yelped for propane refills and this place popped up for a propane refill special for $12.45 through Yelp which is great. I purchased, printed and headed down there. They honored the coupon and filled it up from my tank being totally empty (on fumes) . I noticed the gas prices were a bit cheaper too than other surrounding gas stations. Good place to fill up if in area. read more

I rarely go to any other gas station. They have the best gas prices in the area because they're not as "big business" as, say, Shell or 76. They've always got a copy of The Reader waiting for me, plenty of munchies and drinks, and the guys that work there are really nice. It's awesome to have around, especially since the other gas stations are so expensive (Emerald is usually 5-20 cents cheaper). read more

Maybe 4-5 years ago I use to actually use this station because they were generally lower. Now they are just as much as other stations so I go elsewhere. read more

Best prices and really nice people...they give me a bottle of water every time I fill up. Like that I can support a local business and the local economy. read more

I love this gas station. I get water here from the water machine out front and on occasion fill up with gas. Store is clean and has everything you need plus you get free bananas sometimes which is awesome. Bananas are high in potassium so it ensures me that when I drink my water I won't over hydrate myself and deplete my body of electrolytes. 5 stars. read more

cheapest, biggest gas station around. YAY

Only place I buy my gas if I am able. Very cool workers and you get a free bottled water with every $30 purchase. Its a nice place to fill up before heading to work in the morning and grab a water for the ride. read more

Very nice owner and a great deal through groupon for propane. That being said, I can't believe some of these bitter, whining people who have posted negative reviews. My wife showed up with a CURRENT coupon, was served promptly and courteously and then actually LOOKED at the price of gas to be sure it was the price she wanted to pay (it was) and then filled her tank with absolutely no self created drama. Then again, that's how she and I roll :-) Good times! In short, we were impressed and will come back again when in the neighborhood. read more

The owner of the gas station, Dave, is a very nice and friendly guy. His gas prices are always at the lowest in san diego.

BEWARE - both my credit card and debit card were compromised at this location. I've had friends with the same problem. I've alerted their staff and it continues to happen. Check your local community aps, this is a widespread problem that is being talked about and specifically naming Emerald Oil I'm filing a police report as well. read more

Best gas price!! I live and work in this area since the early 90's. Since the current owners purchased the station, the gas price has been the lowest in the area and their service has been the best. (Although I miss the mechanic's shop, I really like the big convenient store). Also, the staff there are ready to provide you with prompt help. Yes, it helps to know that paying cash keeps the cost lower; since I always carry some "gas cash" this has not been a problem to me. As for the free water/soda, nice touch, especially today that is quite a hot day. Finally, because of their low prices and great service, I say let's support Emerald Oil, our local gas station. Thanks Emerald Oil!! Oh... make that gas to go please... :^) read more

Friendly staff and easiest place in the neighborhood to buy personal shots-when in a pinch. Whether it's 6am or 10pm!

Cheapest gas in the area. If you spend $40 + you get a free water bottle or soda!! They have all kinds of tasty beverages including sparkling yerba mate and tasty lemonade in 4 flavors.Also they have an organic chapstick i pay $3-4 for at henrys for only .99 cents! Emerald oil RULZZZZZZZZZZZZ read more

Always have cheap gas prices. It's a little bit of a hassle cause you gotta pay cash. They do accept credit and debit but you have to pay a bit more to do that. I always just pay them in cash inside. Then you have to walk inside for your change. And you still get a free soda for $40 of gas and don't forget to sign up for the weekly raffle to get a chance at $50 of free gas! read more

I like the cash discount and they have free water when you spend $40 in gas! I would chose this place over Shell or Chevron any day. They are always $0.20-$0.30 less than the other gas stations around. read more

Am always greeted kindly wherever I come here. They are always nice and friendly and happy to help with whatever you need. The gas is a decent price and is conveniently located for me. All the pumps are generally working and receipt paper is usually full. I haven't had any negative experiences really to write about it. Overall I would recommend this gas station to others read more

I had a terrible experience at this station. Not worth going, even for the lower rate. I will find a different station.

Credit Card Payment RIP OFF! Beware if you pay by credit card at Emerald Oil in La Mesa!!!! They charge 5% for every $20 of gas you purchase by credit card and you have no option to, but to go into the liquor store to pay by credit card. You cannot pass on the merchant fees to the consumer!!!!!!!!! Pay by debit card, cash or pennies if you can! Spend $20 you will pay an extra $1.00 (5%) Spend $40 you will pay $2.00 Spend $60 you will pay $3.00 read more

Great prices on gas if you pay cash. But the pumps are really slow. Good part is there is usually no line for such a good price.

I love them warm friendly and the give bananas how kool is that yummy my business continues

I get my gas here. Good prices...they take care of you. Free bottle of water with $40+ fillup. Not much else to say...it's a gas station.

This gas station has great prices and is easy to get into and out of compared to others, however, it's not open 24 hrs.

Everything was pretty smooth and the people were friendly and easy to talk to!

.50 cent transaction charge here!!!!! I'm an Uber driver and you just lost my business to the ARCO gas station down the road less than a mile. And their gas was .11 cents cheaper! read more

VERY nice people and some of the best gas prices for miles. It really doesn't get any better than this. read more

Best Price On Gas, Propane And Everything... Nice People.. Will do what it takes to make you Happy..... read more

I only go to one gas station now, because emerald oil has the best customer service in la mesa.

If it was possible, I would give zero stars for this business! I had a prepaid voucher for 5 gallons of the propane and I now know the attendant was absolutely dishonest. He put 1 gallon in my tank and said that was all he could put in it. He said the tank must not be empty, but I insisted it was and he put in another gallon and a half and said that was all it would take. The total he put in was 2 1/2 gallons and it takes 5. I know it could take more than the 2 1/2 gallons, because it was a BRAND NEW TANK, absolutely empty!! Afterwards, I bought a tank gauge to confirm my assumption and it showed it was only half full. I won't buy anything from this business again. read more

Emerald Gas is located on the corner of Lake Murray and Baltimore so easy access. Plenty of parking and store is very clean and organized. Customer service is good. Best to pay with cash inside whenever possible and paying by Credit is higher. Typically have something 'free' for fill- up tank. Don't always get signs changed to match pump dollars. Still very convenient location and less than name brand so it's worth the stop. read more

I purchased a UT deal for propane. When I went to fill up my 5 gallon tank, there was no one there who could do it. However, the clerk did offer to exchange my empty tank for one of their pre-filled tanks. I am leary about leaky tanks so I opted to come back when someone could fill mine. When I returned, David, the owner, filled my tank and was very nice. Although I did not need gas, their prices seemed pretty good ($3.59 for 87 octane, not sure if that was for cash only though). read more
