Diamond Bar Mobil

I take my car to Diamond Bar mobil for all my service needs. My Accord has over 200,000 miles and runs like brand new. The mechanics are the best in town. I want to thank the entire team for their professional service. Also don’t forgot to get your propane bottles filled up here.

I come here a couple times for week to get energy drinks and gas. Everyone is extremely friendly, and the cashier actually came out and gave me a free water bottle. Never had bad customer service here. The people giving this place 2 stars or lower must think the world revolves around them, get over your self.

Wow! Super hot outside while pumping gas and they came out to give me a free bottle of water! I will be back!

Went in for an oil change the other day and the workers were very helpful. They finished within 30 minutes and the price was reasonable. Would definitely recommend!

I’ve lived in diamond bar for 13 years. This station consistently has gas prices 15 — 25 cents higher than the 2 stations a block away. I have also been here 2 times for smog checks. The first time after it didn’t pass they tried to get me to have a bunch of expensive repairs so I told the guy no way, took it to a different place where it passed with no repairs. I had to forfeit the money I already paid. Then about 3 years later I had another car that needed to be smogged. Stupidly I decided that due to time constraints and this stations close proximity to my home I came here again. What a mistake! This time they do the check and tell me it passed. I call my wife and tell her the good news. I then read the paperwork and see that it actually did not pass. Needless to say I will never go here again except to get my propane tank filled. The only good thing about this place is that they sell propane and no place else in db does that I know of.

i’m from out of town and was trying to get home and i went to 3 other locations before stopping in @ mobil. the other 3 places i stopped at told me it would be 2 hours before they could repair my tire (crazy) i pulled in to mobil gas station and it was about 6:15pm and they looked like they were closed a man walked up to my car and asked me if i needed help, i explained to him my situation and he opened up garage door to help me and within ten minutes i was on my way home… great customer service… thank you paul…

Why is gas always significantly more expensive here??? Suspicious???

If I could give this place negative stars I would! My bf decided to take his car here to have the clutch fixed on his 2002 Acura RSX-​Type S since the place was close to our house. I told him not to go there, but that’s another story. He dropped the car off on 06÷09÷14 and after discussing the problem and the length of the job (8 hours); the bf advised the guy he was dealing with that they could keep it until Thursday. The guy said they would have it before that. The bf stresses that he needs the car by Thursday 3PM because he has to work that night.
Thursday rolls around and the car isn’t done since «their guy was out sick on Wednesday». HOW IS THAT OUR PROBLEM? I had to leave work early (no pay) so that my bf could take my car to work that night. Then on Friday, the car is still not ready. Oh yes, the clutch was replaced, but now the car won’t start at all. Oh and they can’t figure out why. So, guess what? The car was towed to an Acura dealership for a diagnosis. REALLY!!! We should have gone there in the first place and saved ourselves the trouble. So, Friday he has to borrow his brother’s truck to go to work. Saturday and Sunday go by with no car. The bf keeps calling for updates and is being told «the car is at Acura».
So, here it is Monday, June 16^th and we still have no RSX. I decided to call the local Acura dealers to find out where the hell the car is and what is going on. I find the car and it turns out that it was sitting at Acura all weekend because they couldn’t get to it. Monday/​Tuesday were diagnostic days so we still didn’t have the car. The bf is doing this and that to get rides and what not. Mind you, we live in Diamond Bar and he works in Long Beach; and he works odd hours so it’s not like he can just jump on the bus. They have now had the car for a week and there is no offer of a rental mentioned. I decided to call the owner and discuss the problem with him. Although he was very nice, he was also very clueless. He did agree that if the car wasn’t ready by Wednesday/​Thursday that they would get the bf into a rental car. Yeah right!
Finally, they get the car back from Acura and it turns out that the timing chain was off and there was a problem with some other thing related to that. Both items were fine before the clutch job. In fact, the car was running tops until the clutch problem. So, once they got the car back from Acura (on Friday), they begin work. During this whole ordeal, we are in the process of moving. At the end of it all, the car was not returned to the bf until today at 1-​ish. Then they have the audacity to tell him that they won’t charge him for the repairs to the timing chain and what not. WHAT??? Of course you won’t since you broke it! These guys are total jerk offs! My bf was without his car for over two weeks because their mechanics are a huge joke. And the kicker is that they didn’t even offer him any kind of compensation or discount off of his bill for the huge inconvenience.
We have all learned a lesson here… STAY AWAY FROM THIS PLACE!

DO NOT get ANY automotive repair done here! These people are completely unethical! They will over charge you many times over RETAIL on parts and charge labor on stuff they didn’t install! When you call them on it, they are rude beyond belief.
I am filing a claim with the Bureau of Automotive Repair. I suggest that anyone else who feels they have been ripped off by these guys to do the same. It’s the only way to actually have any recourse.
Why would you want to pay their outrageous prices on gas, as well?

I was lied to. I was told my car did not pass smog. Therefore I had to pay $ 100 to get it checked out. My brother in law told me not take the car to mobile station. He also had problems. I took my car to another location in pomona as it passed. I still had to pay $ 54 for the check.

Go mobile my tire pressure was low and they fixed it and they were so nice I love this gas station oh and by the way I hate Chevron

Takes to long for a simple brake and light inspection dropped my car off at 945am it’s 315pm and it’s still not done. They also told me that the inspection couldn’t be done because the inspector never came. This type of inspection is not something that should take 6 hours. Wouldnt come here but unfortunately it’s the only place that does it near me.

If I could give negative stars I would! I went there for a smog check and these guys robbed me. I have a after market air filter and is noticeable when you look under the hood. Their policy is they can’t complete the smog check unless I put my original air filter back on… fine! So why charge me for a smog check if you could see very easily that I didn’t have the original air filter. I asked them that and they couldn’t give me a straight answer. Beware of this place! A garage run by crooks!

I’ve been taking my cars here for years and would recommend. The owner of this station has owned it for decades. I just got my car smogged and was out the door in 20 mins. You can walk next door to Mr. Wok to get a bite to eat while you wait. I have never had any trouble with them trying to upsell me or any of that BS. Very courteous and professional. The only reason I did not give 5 stars is because this place gets BUSY on the weekends and sometimes there is a long wait.

Wouldn’t take my credit card, I’m assuming it’s because I haven’t had money to pay my bill since October. The guy inside actually said hi and was friendly.

Changed oil here and found a pool of liquid under my car 3 days later. Turn out to be oil, took the car back here and it was some under qualified tech, who broke an o-​ring while tightening the oil filter. Very unsatisfactory experience. A tech friend told me that my car engine would’ve blow up if I haven’t caught it in time.
They changed a new oil filter and cleaned the bottom of my car. Also reimbursed me on the 4 qt of oil I bought to get me here in the first place.
Wasn’t a great experience but they did take care of me at the end.

Steve is the head mechanic. I though he was honest and was referred there. Well its a long story but here it goes. I had a leak on my driveway under the drivers side behind the wheel. It was a pretty big puddle but didnt seem to be motor oil. I had to get my timing belt done and water pump so I took it in to Diamond Bar Mobil where I spoke with Steve. He calls me up and tells me the leak is a valve gasket. Its gonna cost around $ 1800 for the gasket, timing belt, and water pump. I said okay go ahead with the work. I get my ar back and the next day there is the same exact leak, same size and same location. i call him up and tell him and I said it sounds like a warranty right? «well bring it in and we will check it out». Okay I bring it in the next day. He then calls me and tells me its the rack and pinion. I said that is why i brought it in the first place there was no other oil leaks. I did not know it was the rack and pinion that was leaking and the whole steering rack and pinion needed to be replaced. That was going to cost another $ 800+. I said no way. the work should have done right the first time. He told me to «go pound sand». I said theres got to be some way to work this out. He said «you think you have any say in this and you think the ball is in your court, well its not». We ended up negotiating and he did do the rack and pinion for cost. I looked up the price and he was cheaper than what I could buy the part for. So all is good right? Not so fast. I get the car back and check underneath when I get home. The rubber boots on the rack and pinion are all twisted up and installed wrong. i had to take it back a third time for them to be installed correctly. Now they realize the check engine light is on. I knew this before I took it in. Steve now wanted to charge me $ 80 to diagnose. I had just spent over $ 2,000 and your gonna charge me $ 80 to put your scanner/​computer and plug it in to find out whats wrong that takes about 5 minutes? No Thanks. My wife and I now use another mechanic down the street.
