At Superior Auto Service Center, we help our Frederick customers' cars run as cleanly and efficiently as they possibly can. We provide a range of emissions testing services to ensure that your car is running and driving its best, as well as complying with all local smog regulations. Should a problem arise with any of your vehicle's emission systems, we provide the parts and expertise to get you back on the road. Superior Auto Service Center can replace mufflers/catalytic converters, refill diesel exhaust fluid, and make sure the full range of filters in your vehicle's exhaust system are working perfectly.
Regulators understand that older cars simply can't meet modern emissions standards without extensive modifications. For newer cars however, passing a smog test is a requirement of road legality. Call us at 301-682-3533 to learn more about the emissions requirements for your vehicle.
Emissions testing (also known as smog testing) is a vital part of the maintenance of your vehicle. E-tests provide your mechanic with important information about your car's engine and exhaust system. If important components, like your car's catalytic converter aren't working properly, the car isn't running as it was intended to by the manufacturer. Inefficiency costs you extra money in fuel and does unnecessary harm to the planet. Emissions testing can also affect the value of a vehicle you're trying to sell; while you can still sell a car without a valid e-test certification, you'll get more money for one that has passed the test.
There are several reasons that a car may fail its emissions test. There may be a problem with the vehicle's fuel system adding too much fuel to the air-fuel ratio required for proper combustion within the cylinders of the car's engine. This is known as "running rich" and results in the smell of gasoline from fuel passing through the engine and exhaust system without being fully burnt. Causes of this issue range from faulty fuel injectors to issues with the engine's control computer. There may also be problems with oxygen sensors or the vehicle's ignition system. At Superior Auto Service Center, we use a complete set of diagnostic equipment to determine the problem and fix it quickly, explaining every step of the process to you, our valued patron. Call us at 301-682-3533 or send us an email to arrange a health check for your car's emissions system today!
I've got 3 cars and I take all of them there when work is needed. These guys are thorough and honest! I've been a customer since 2006.
Fantastic and Honest people that go above and beyond to help you... Can't recommend them enough...
The best customer service, transparency and honesty I have ever experienced when working with an auto repair shop. They will be upfront, and go the extra mile. My vehicles will never be serviced elsewhere.
I have been with Superior for 3 years with my 2001 Jeep. They do all my work and I am 100% satisfied with they work and I like the way I'm treated, not like a customer but a good friend. They show me what is wrong so I don't have to take their word for it. If I need a ride home or be picked up to get my car they are there for me. I think I'll be with them for many more years.
Absolutely the Best! Superior and the team is like family, trustworthy, a clean shop and a pleasure to work with. As a single lady, choosing a good mechanic can be daunting. I don't even want to take my truck anywhere else. The guys at Superior drove my vehicle with me and listened for problems. They described the problem to me so that I could really understand, and their service was fast! They will help with regular maintenance so I won't have to worry about missing important upkeep. They really are SUPERIOR!
Very knowledgeable and honest guys. Was able to get an estimate before the work was even done. Very friendly. Pricing is not the cheapest around town but reasonable (There is also the old adage you get what you pay for). Would recommend and will do business with them again!
These guys are awesome! I was treated like family from the minute I walked in the door. They listened to my concerns, gave me a detailed description of what was needed, found other maintenance concerns, gave me a detailed estimate and even told me what could be differed until next time. Integrity comes to mind when I think about my experience. You can trust these folks with your ride. Highly recommended!
These guys rock. Recently I started my car (while parked in the garage) and it was leaking fuel. Then, died on me. After calling these guys, within two hours they arranged to have the car towed and by that afternoon provided me with an update. The next morning they called with an estimate for the repairs. Ironically, this happened the DAY BEFORE I left for vacation. Not only did they provide amazing service from the very beginning, but they took care of the repairs and the car was ready for pickup upon my return. This gave me peace of mind while I was away. They even came to my house to pick me up to get my car when I returned! Reasonable prices for work performed (replaced fuel filter, PCV valve, etc.) and the car's been running smoothly ever since. So happy with Superior and highly recommend them.
I just want to say that Superior Auto Services are awesome! They have a great professional team. They always greet you with a smile and work around your schedule. Usually it is the same day service. One time I was there I was having a problem with my Subaru acting like it wanted to shut off but not all the time. They drove the car 13 miles before it would act up. How many auto services would do that.? Probably zero to one. I highly recommend them to anyone!! I will never take my car anywhere else. Also they were highly recommended to me. Thanks for keeping my Subaru running greatly appreciate everything you have done for me!!!!
After living in the Frederick area for several years I was happy to find Superior! I was coming off an experience where getting my oil changed at a high volume oil change business didn't tell me I needed an alignment and had to purchase a new set of tires prematurely. Superior has great customer service. I really appreciate the time they spend explaining repairs and repair options. I appreciate and use their shuttle service. I appreciate that they are a full service shop and can take care of any repairs my cars need. The only small nit I have is that their price on parts can be a bit high. I also appreciate that their price for an oil change/tire rotation is reasonable- that's big for me!
If I can take my car there..... you can to, because I'm picky.
Outstanding in every way, couldn't be more pleased, they live up to their name. Will be a loyal customer from now on; highly recommended.
Dealer service can be frustrating. So when that happens try Superior Auto Service just off of English Muffin Way. They're friendly, courteous and thorough. Reasonable pricing too. Got that at your dealer? Just a thought!
Excellent shop, highly recommend. I went into the shop on MLK day around 10:30am to inquire about having an aftermarket exhaust I had purchased installed. They said as long as everything lines up and no issues, 1 hour labor, they scheduled me for the next day. Next day I dropped it off in the morning and picked it up at the end of the day, same price I was told 1 hour of labor. These guys did a great job and were able to fit in my exhaust without needing to wait a long time for an appointment. They also have a shuttle service that dropped me off at work and picked me up when the car was ready. I know where I will go when I have other automotive needs, go there with confidence.
