  I’ve been going to the same store for years. Grease Monkey on 10th Street helps me keep my vehicles properly maintained.

  I will always go to this grease monkey. Management and the workers are always so friendly and work with me when I need it. The manager on duty today was awesome I got there and had realized that I lost my wallet at the last place I was previously at he worked with me so I could go find my wallet. 10 minutes later I was right back with my wallet to pay for my oil change. I will continue to go to this grease monkey the staff and management are awesome

  I had such a great experience getting my oil changed here! From the moment I pulled in, the customer service was truly above and beyond. The staff was friendly, professional, and incredibly attentive. They took the time to explain everything clearly without making me feel rushed or pressured. The service itself was quick and efficient, but what really stood out was how kind and respectful everyone was. It’s rare to find a place that combines speed, honesty, and genuine care for their customers the way this team does. I left feeling confident in the work that was done and genuinely appreciated as a customer. I’ll definitely be coming back and recommending them to everyone I know!

  I’m writing this review after comparing two very different experiences at Grease Monkey in Greeley one at the 10th Street location and one at the 35th Avenue location — on the exact same morning. My husband went to the 35th Avenue location with his Dodge Durango, and I went to the 10th Street location with mine. We both drive Dodge Durangos, so the services should have been fairly comparable. While I understand I approved a few add-ons, the overall difference in cost and experience was frustrating. I arrived at 10th Street at 8:00 AM and didn’t leave until around 9:00 AM. Meanwhile, my husband was three cars deep in line at 35th Avenue (with only one lane operating) after arriving at 9 am and was still home by 9:25 AM. His service was efficient, straightforward, and significantly less expensive. What’s disappointing is that both locations have access to shared service history and vehicle information. So why did I feel like I was automatically upgraded to a premium oil change and additional services? The pricing difference doesn’t sit right, especially when comparing receipts side by side. My total was over $240, while his was nearly half that amount. I can’t help but feel like I was upsold unnecessarily. As a woman, I would appreciate not feeling pressured into upgrades that may not truly be needed. I understand that some of the responsibility falls on me for approving services, but the contrast in experience between the two locations is hard to ignore. To be clear, I’ve had good service at 35th Avenue before which makes this even more disappointing. This feels like a consistency issue between locations. Customers shouldn’t feel like they need to be on guard depending on which branch they visit. Lesson learned! I’ll be more informed and ask more questions moving forward. But I do hope management takes a closer look at consistency, transparency, and how recommendations are communicated across locations.
