Given they were about to close… These guys helped me out with an oil change last minute. They were very friendly and professional. They didn’t try to push anything on me and helped answer all of my questions.

Somehow was charged more than advertised and the staff were mediocre. Not very attentive and mostly concerned with upselling their services. I have service records from a radiator flush 3 months ago and the guy literally told me “if I didn’t do it then as far as I’m concerned it’s never happened and you should do it”. Was not thrilled with the service and will not return to this location.

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.

I recently went to Grease Monkey for an oil change. Make sure you ask for Jeff. He will always give you an honest answer. The service was quick and efficient, and the technician, Jeff, was courteous and helpful throughout. While I wasn't initially aware that topping off fluids and checking tire pressure were included in the oil change, I appreciated that Jeff took care of these without me having to ask. He also mentioned that my tires were showing some wear and recommended an alignment. As someone who isn't very familiar with cars, I found this advice to be very helpful. I wasn't pressured to get the alignment done because they don't do them. He was just making me aware. Thanks to Jeff for the great service and for making sure my car is in good shape!

Quick service and Great costumer service. They suggested a few extra stuff, but they were respectful on my response and they were not pushy to try to make me buy their suggestions. This is not my usual location, but if I’m in the area no doubt I will go here again! Thank you Grease Monkey staff!

My low coolant warning light came on, so I stopped by today and Scott, helped me understand why the light was on and to take it to a shop to have it looked at incase it needs to be replaced . He and his staff were very professional and kind.

While the location doesn't sparkle like a gem The service is top notch. Last time I got my oil changed in less than 10 minutes! The staff is always courteous and friendly and they make appropriate recommendations based on what I truly need, not just to drive their numbers higher. Way to go Grease Monkey

Asked for a synthetic blend was charged for full synthetic, asked for 5w30 got 0w20. Denied the filters and went to replace myself 30 min later and the air filter was jammed in the intake wrong and the cabin filter door wasn’t securely replaced. Id recommend taking your car somewhere else for service. Theres cheaper places that will pay better attention to details rather than rushing through the work.

Everyone there is polite and professional. You can tell they have a good team and a good system that they all operate on efficiently. Even though it was super busy, they still took their time to focus on good customer service and I was out of there before I knew it. Solid experience every time.

Decent service today. Scott and Miguel were quick and friendly. Got some good clean oil. A little strange to get a checklist marking off things checked like tire pressure and clean windshield and double checking for myself to see them not completed. Interesting business practice but hey all I really needed was clean oil. Thanks
