Grease Monkey

"On December 1 I took my car in for an oil change. Yesterday on my way home I got a warning I was low on oil. I put 2 Quart in and stop by to have it looked. All they did was check the dipstick. Then told me it was a gasket. Never once looked under my car. This morning I went to the one on 104th and Colorado. Told them what happened. They were happy to help me. Guess what it wasn’t gasket the filter was put on right. I will never come back to this one. If you don’t want to blow your Engine I would go somewhere else."

"I recently visited Grease Monkey on Washington and 88th in Thornton for an oil change, and I must say, it was a great experience from start to finish. The staff was incredibly knowledgeable and attentive to my needs. The oil change itself was done with efficiency. The team worked diligently to ensure that everything was done as I had requested, providing the synthetic oil I specifically asked for. They even changing my windshield wipers, demonstrating their dedication to comprehensive service and my safety on the road. The combination of service, attention to detail, and friendly staff made it a truly memorable visit. I recommend Grease Monkey to anyone in need of an oil change or any car maintenance needs. Thank you to the entire team at Grease Monkey for providing such a great experience!"

"I like the friendly faces and the timely quick way that they get done. And they don't try to oversell any products to us. And they were honest about my oil filter. That I didn't need one just yet. Thank you, grease monkey. I'll be back."

"I’m not sure how to add two reviews. One is for the actual office itself. which I give a Zero! The owners won’t fix the AC apparently. They don’t turn on any of the AC and it’s probably 100° in here while I’m waiting for my car. The service is on point. 4 stars. Kind and professional guys. They always do a great job, but I wish whoever runs this location would pay attention, I can’t imagine what these guys are working in and being a customer in here I had to go outside it’s too hot in here."

"Since June 19 I have been waiting for Grese Monkey to respond because they damaged the engine of my car by doing an oil change and not putting the screw in the oil tank, as a consequence the engine was ruined and as of August 15 they have not done to solve the problem. they left me without a car. I hope no one hires the services of this company and if anyone else has had problems with them we should come together to make a class action lawsuit. We cannot allow companies like this to abuse people. OLD POST ==== this is incredible. On June 19 I filed a complaint for the poor oil change service by not putting the cap on the oil tank causing my car to not want to drive. To date I have the car stopped at my house and they only call me to ask for more photos, more details and they do not solve the problem that they have caused me. I am almost 2 weeks without being able to use my car. They called me to tell me that they are working on my case and I am still without a car. to whoever sees this complaint NEVER USE THE SERVICE OF THIS COMPANY. NOT only do they damage your car, they do nothing to solve the problem THEY CAUSED, they just call to ask for more information, I think they are waiting for me to get tired and leave things as they are.Bad work and service. The manager 0% gentle."
