"Excellent service, great price, tried them out today for an oil change."

"My husband said they purposely shorted the battery to extort more money from us."

"Friendly staff, fast and good location."

Was on a multi-K mile road trip and needed an oil change. My truck is picky so I travel with my own parts. This outfit was to the point, fairly priced, and as efficient as I have ever seen. I live a couple thousand miles away but wouldn’t hesitate to use or recommend them. Great business.

Repeat customer here. They won me over in the last two oil changes! Very fast service and they don’t try and upsell you on a million different things (like some other places 😑.) Staff are nice and get the job done!

Absolutely the best service with Tim (the owner/manager?!) giving invaluable advice on my engine and subsequent oil change. Super knowledgeable, friendly, and honest. Not sure about the other staff, but make sure you seek out Tim if you need additional information besides a basic oil change. Thank you Tim and rest of staff!

They cut my engine cover flap off the area that needs to be folded down to access the oil filter. This cause damage on the underside of my car as a result of it not being covered. The also didn't change my oil filter. I change my own oil every time omitting maybe once a year when I do not have the time. When I changed my oil 3 months post them changing it, it still had the same brand filter I used. I contacted grease monkey to ask which brand oil filter they use. It was a completely different brand, color, etc. I will never return to this company. I have tried to contact them multiple times, including using the link that is listed below in response to this review and received no response.

I was looking for a drive-through oil change oil change experience, which usually is what Grease Monkey is - this location is NOT that - there's only two bays and you have to get out of your car and wait in a waiting room. It honestly looks like the Grease Monkey chain bought out a smaller garage. They warned me of a long wait when I got there, but ended up getting me right in and doing a very quick oil change and check of my fluids and tire pressure. Overall an excellent job and very quick service, though I think I must have hit it at just the right time. They did point out that my cabin filter was due for a change, but I went to an auto parts store nearby and got one myself instead of paying them to put it in. Overall, very satisfied!

It’s so hard to find honest mechanics and these folks are the best. We’ve been going there for about a year for minor stuff, oil changes, air filter changes, and they will never lie to you or try to get you to purchase something you don’t need. In fact I went to a dealership that said I needed new brakes soon and I wanted a second opinion and the grease monkey said I was still good for a while. The manager/supervisor is a really great as well, super honest and a nice guy.

Tim and his crew did an excellent job. He originally recommend I take the vehicle elsewhere that could do a more in depth job. I came back and kindly requested he do what he could after not having luck at the other locations due to co cerns about my situation and timing being an issue. The team went beyond my expectation and answered every one of my questions. They were the most transparent and and upfront guys I have had the pleasure doing business with. Small business style and laid back atmosphere. Will definitely return.

I took my Toyota Venza here in late November ‘22 for a basic oil change. Here’s what they actually did: - changed the oil - charged me for an extra quart - stripped the screw on my negative battery terminal when “testing” - inside my glove box, left me with no cabin air filter and unhooked my glove box spring so it now falls down when opened - $135 for an oil change and engine air filter - I should have walked out when the lady before me in line said to the employee “sir, I had an oil change here last week and now my car is smoking” I’m not saying they are the worst I’ve ever seen, but take this information and do with it what you choose. Needless to say, I’d never go back. But I do highly recommend the Toy Shop on Cherokee St. in Denver for anything Toyota/Lexus related. Greg is a real mechanic, he’s worth the wait. Skip the greasers. This is the first negative review I’ve ever left publicly on any business in my life. I’m disgusted with the place.

Never had a problem with this business. They have seemed to be honest and direct with me every time I've brought my vehicle in to be serviced. My car is usually semi vacuumed out and they top off your washer fluid and check all the other stuff they can while they change your oil. I've been going to grease monkey for 8 years, different locations, different cars, etc, and I can say I trust their services.
