Kwik Kar Oil Change & Auto Service Center of Denton

I've used this location for both the simple maintenance stuff and major engine repairs and am very pleased with their work. They're warp-speed fast, reasonably priced and clearly explain exactly what the problem is. On more than one occasion, they actually charged less than the estimate, noting it wasn't quite as expensive as predicted. At my age, it's important to have a mechanic you can trust and these guys definitely fill that need.

On November 17, 2025, I came in because my check engine light kept turning on and off. After being told that replacing the mass airflow sensor and the oxygen sensor would resolve the issue, I spent an entire day waiting—only to pay a substantial amount of money and get back on Loop 288 with every light on my dashboard lit up. When I returned, they removed the oxygen sensor they had just installed because, apparently, that was what caused my car to malfunction. In other words, they were guessing from the start. Despite that, they had no problem charging me for a part that clearly did not fix my issue. After wasting two full days at this shop with zero resolution, my check-engine light is still on, and now I’m being told the problem is the fuel pump. It is unacceptable that I was charged for unnecessary work while the actual problem remains unaddressed. To make matters worse, when I returned on the 18th to express my frustration, the manager behaved extremely unprofessionally, taking my keys and walking off without a word. I am almost sure he insulted me, based on the staff's reaction. This entire experience was unprofessional, careless, and dismissive. I strongly advise anyone considering this location to take their vehicle anywhere else. I should never have been charged for guesswork.

I pulled up and one of the workers came out promptly and let me know it might be 20 minutes or so because they were a little busy at the time. Completely understandable and I was willing to wait 20 minutes so I parked and walked in. Walking in the office, I didn’t feel welcomed at all the young lady at the front desk made me feel like a huge inconvenience. You guys need someone who can at least fake a smile. Zero customer service skills. However she did perk up as I left telling me to have a nice day so there is that I guess. When the mechanic invited me to the garage to inform me what was going on, he was really nice and courteous which I greatly appreciated. He suggested a couple different services I may need but at that point I had waited so long I could only get the oil changed. He is the reason you guys didn’t get 1 star. When I left over an hour had passed and I was late to a work meeting. That’s a bit longer than the estimated 20 minutes I was told when I pulled up. I do reviews like this all the time because real “service” is dying more and more with each passing day and I will do everything I can to attempt to keep it alive. I’m actually really passive but it’s painful for me when businesses can even do the basics at a mediocre level. I will give you guys another shot and will change this review depending on how it goes.

Manager and staff are professional and willing to explain all issues regarding my car repair. It turned out not to be the original issue. That saved a lot of expense. Will always take my car to this great location. Happy customer.

Beware!!! My experience having them just do a vehicle inspection was fine in the past, but when I came in with a check engine light on, they saw dollar signs! $$$$$ - Charged 2 different fees adding up to $100 just to look at it. - Told me my brand new break pads were completely worn out. (Verified by my mechanic friend and another shop) - The bid included 2 hours of labor (at $150/ hour) to do a job that took a mechanic friend less than 15 minutes. - They were going to charge me $150 for a sensor that I had in the car and cost around $20. - The total bid was almost $2,500! - After replacing the sensor myself (with help from a friend), I took it to an honest mechanic and saved over $1,000. While the price and speed of a vehicle inspection at Kwik Kar is good, they have lost my trust and business going forward. If I could give less than 1 star, I would.
