I stopped here for gas and was paying cash so I went inside. The cashier never came out so I left and took my business elsewhere.

its very hard to find hones and trust worthy people in the service industry. I had a problem with my old van 91 ford. I use the van for work. anyway the van sometimes would not start in the morning or it would crank forever before it starts. I took the van to several places and everyone wanted in arm and a leg to just find the issue. So as happens to be I pull up to the gas station to fill gas, and as the tank is filling up i saw the repair shop. I asked a guy their by the name of Vu if he knew what the problem might be. Vu gave me the possible problems and cost. Right their and then I felt the difference in service. He did not pull the clip board and point out the cost of the labor per hour. Vu has great sense of customer service I can tell because I am business owner. Their is great effort put into fixing the problem and making sure the customer is happy. The prices are very reasonable. Since then I have been taking all of the vans for whatever attention they need. I like the service most because of the comfort level in the atmosphere. I didn't feel pressured to sign anything. I didn't feel they are trying to sell me anything I did not need, and importantly they explain whats done to some of us out their who are not mechanics. Give this shop a Try and see for yourself read more

Mechanic here is honest, fair, and always willing to help. I had a flat. For a week he helped me pump my tires and diagnose the issue, then gave me a good price to replace two tires (done same-day). Thanks for the great service. read more

Friendly station with good service. Bill Davidson who handles most older cars and in particular Volvo (Bill was formerly manager at Volvo Centrum) will tell you exactly what needs to be done and what can wait. His prices are fair and he uses OEM parts whenever advisable. When something goes haywire, Bill will fix it. I would highly recommend Bill. I have been going to Bill for 20 years. read more

Came here at the very end of the day for an overdue smog check and half-expected them to turn me away. Instead, they were super-friendly, polite and did the smog check asap! I am grateful that they were so helpful and responsive! I would definitely recommend Guerrero Shell and will come back! read more

Came in to get a gas can and 1 gallon of gas. Ran my debit for 24 dollars. Looking at my statement online and noticed an additional SEPARATE charge of 50 bucks and some change. Printed out my statement, took it down there where I was told the "merchant "numbers were different, so it must have been another location. Since that was the only Shell I went to that day, I reported an unauthorized charge to my bank. They looked into it further and found that both charges went through a separate but identical location on Oak st. WTF?? SHADY read more

Vu is friendly, fair, and honest. I brought my car (Honda Civic) here for a smog check and it only took 20 minutes. He made some suggestions about upgrades but didn't pressure or try to up-sell me in any way, and I was on my way after paying $68.20. read more

Called to see if they had a tire that i could buy, was told to come in and they would have it.... I tried to double check and all i got was "yeah, yeah, yea come in we got you." i showed up and they didnt have the tire, couldnt get one till the next day and tried to charge me $295 for a $165 job (thats what i ended up paying somewhere else.) They then told me that this is a way for them to guarantee business, just tell people "yeah, yeah, yeah we got you." They called the police on me because i was upset and couldnt move my car, they showed up and i told them what happened and they laughed at them and told me not to worry about it. read more

Vu is great! I have been taking my car to this shop for over 4 years now and he has never failed me. It's a plus that I can see the shop from my window. He is quick and his prices are reasonable. He is an honest mechanic and I highly recommend this shop!! read more

Drove up out of the blue a couple weeks ago for a smog check. Vu was quick to assist. Due to the weeks if not months per year in lack of use, I failed the discounted first, but passed the second one free of charge. Thanks Vu! read more

I brought my car here, a 1998 Cadillac, to be smogged. They were fast, courteous, and totally straightforward and reliable. I highly recommend them. read more

Was referred by Volvo centrum to fix horrible noise in my 2002 Ford Taurus. Vu and mechanic diagnosed left rear wheel brake drum and hardware. Fixed by next morning. Terrific service and friendly interactions. Charlie read more

If you need a smog check, or service, don't think twice, this is your place and Vu is the man! He's very helpful and understanding. My car failed smog at first, and I had to take it out for repairs. Vu didn't charge me until I passed, he's a class act and will go the distance to help you out. He understands that happy return customers are better for his family business than ripping people off one time so they never come back. Thanks again Vu, I will send all my friends and family to you! read more

Smog check- No appointment necessary and the best price of the three places I called. He also provided pricing for work he recommends I do on my car but wasn't at all pushy about it, I appreciate his professionalism and concern! read more

Vu is super extremely helpful. He can detect anything on my Toyota Camry. He is super reliable and honest. I totally trust him with my car. He even gave me advice regarding my car and how it's not worth it to spend so much money on it. Definitely it helps to have a great car mechanic like him. read more

I went here for both a battery and a smog check, and Vu has been very helpful in figuring out my car. He's friendly, trustworthy and knowledgeable, and the service was great. read more

A friend recommended i check out, Vu, her mechanic, and I have to say i was totally impressed. I was headed to relocate to Portland, Oregon and wanted to get my oil changed. Not only did Vu change my oil, he offered to put on my new windshield wipers for free, filled up all my other fluids and did a quick look over of the car. Not to mention, he's really personable and swift. 5 stars for Vu. read more

Car didn't pass a smog inspection elsewhere. Took it to Vu's to get it diagnosed. He gave me a few options for possibly improving the outcome of the test before having to fix anything. When those didn't pan out he took my car in and diagnosed and fixed the issue that day even though he was busy and I was a walk-in because I had a DMV appointment the next morning. He didn't have to do that but called me with that surprise! And when I had to wait for the car and had a few hours to kill, it started to rain and he ran into his garage and dug an umbrella for me out of a box so I could stay dry while killing time in the Mission. Next day when I got my plates I stopped in for something real quick and Vu ended up offering to put on my plates for me and gave some solid advice on my old old car for free. Really felt taken care of. read more

Quick and easy smog check with no advanced notice. $20 off with yelp offer.

Great and super fast Smog Check (Star Certified). Checked in and saved $20. Definitely my go-to Smog Check station.

Good service. They were able to take care of me on short notice and got my smog check done while I waited.

My mechanic did a major tune up on my vehicle and I ask would it pass Smog, he said of course with flying colors. I told him I would go to the Shell down the street to get the Smog, he almost begged me not to go there. I said, I know enough about cars' to make sure I'm ok. I watched my smog test, the guy (Du or Vu) said it was missing (the engine not in sync) I walked over and looked at the spark plug wires and pushed it back onto the spark plug. Du or Vu said, "Oh, you know about Cars?" And he actually got angry, I said I should be the one mad. I told him he's done enough and to disconnect my car I was leaving. 30 minutes later, I went to another Smog Station and passed with flying colors. This guy Du or Vu is a real nut job. I reported this Shell Station to the Better Business Bureau , California Smog and the Automotive Commission of California. Please read these reviews, and more importantly tell your friends about stuff like this. read more

I am surprised that Guerrero shell only has 3 stars. Then I go to the filtered reviews and those reviews sound more that the Guerrero shell I've known for 5 years. I came across Guerrero Shell when my 1996 VW Jetta overheated after a Giants game. Vu Fixed my car and I was able to drive back to San Jose! Vu was very up front with me about the cost of having my car fixed.... $800! He advised not spending that much for an old car with 200000 miles on it. Instead he put a bandaid on things which cost me $160 and I was able to drive my car around for another year. Now I take my 2010 civic all the way to sf for maintence. I know that Vu will not rip me off! read more

Took my car for smog check: nice, friendly and fast service. Got a call back in 20 min that car is ready. Report said that I was running low on oil (my bad, it was near empty): they just filled it up at min charge. Everything went as smooth as it gets. read more

Best and most efficient place to do smog in SF....and it's a deal with the yelp coupon. Nice guys!

Quick, efficient, inexpensive. Took both my cars there, one is an 88 BMW. Technician advised me to add a higher octane gas and drive it around for a while. Great advice, the old girl passed with flying colors. read more

Faster than expected and pleased to save $20 with the yelp coupon.

Vu was awesome. Very prompt with helping me, quick and thorough smog check and a fair price. I really appreciate a business that operates this way. I'll be back! read more

I go here all the time because Vu is reliable, competent and trustworthy. He is also very quick. I have a 99 Volvo with a wonky computer. Vu always works super hard to help it pass the smog check. read more

I needed to bring my 2006 Prius for a smog check (first time smog for my Prius) so I called the Shell station on 16th and Guerrero. The mechanic said they are able and that they were availabile if I have time to come by. I dropped off my car, walked to Tartine, had a coffee and pastry, walked back (about 30 minutes later) and my car was ready. The mechanic was genuinely friendly. This place is also a quick 5 minute walk to Valencia st . Will return to support this gas and service station again. Fully deserves 5 star rating! read more

Went into Shell looking for an Oil Change. Left there with an Oil Change and Smog Check. The 2 workers there are very nice and professional. Killed 2 birds with 1 stone for me. I highly recommend these guys. read more

Showed up at 10 on Monday morning, and was done by 10:30. Reasonably priced and fast, friendly service.

Great experience at Guerrero Shell - had to get my hybrid services for smog and an oil change. They were fast and super professional! Would highly recommend! Thanks. read more

Wu is amazing. Excellent, quick, reliable service despite my last minute call. Highly recommended!

Vu was amazing. I went in for a smog check, and he informed me that the catalytic system was "not ready" and so test could not be done until it was. It was all mumbo jumbo, and thankfully for a small fee he offered to take the car for a day and put it through the paces to fix the problem. He said if he couldn't he wouldn't charge me. Next day problem solved, smog check passed and I was on my merry way- stress relieved. Vu had a smile the whole time through. Thanks! read more

Brought my car here for a smog check 30min before closing and was done in 15. Vu was friendly and seemed like an honest and hardworking guy. He honored the $20 Yelp discount and the total came up to $48.20. read more

Fast & friendly! Free re-check, if fail. Even topped off my low oil free! Highly recommend. $58 w/ elec cert trans.

I just had the best mechanic experience of my life. I hit some debris on the 80 coming back from tahoe and my subaru outback started making a horrible screeching noise on the front left side. I took the car in without an appointment and the mechanic took my car in immediately. We looked at it together, he put the car up on a winch, took the tires off looked everywhere and couldn't find anything. He took the car back down put the tires back on and started it while still on the lift to hear the noise again. That next time he took his screwdriver through a hole in the wheel and pushed back into shape a metal shield that had been pushed into the inside side of the brake rotor. Voila, all fixed without any expensive new parts, or waiting around. read more

First yelp review ever- these guys are the best! So fast! So easy! They even took me though I got here 5 mins before closing time. Thank you Guerrero shell!!!! read more
