Grease Monkey

I have been using Grease Monkeys all over Denver for some time now. They have used a «Synthetic Blend 0÷20» on my car every time. I went in for an oil change this evening and the gentleman told me that the only oil that’s allowed for my vehicle is full synthetic. I told him I have been using Grease Monkey for a long time and no one has ever told me that. I asked if they could check the system to make sure I was correct and the young guy told me that they could all get fired for using anything but full synthetic (which of course is more expensive). His manager never once came out and talked to me, the poor young guy just kept having to run back and forth between me and the manager (by the way I was the ONLY car there, so the manager wasn’t busy). He probably went back to his manager 4 times or so? The young guy was very polite and professional but I kept asking him why last time they used a blend and he said he didn’t know but that they couldn’t help me. I told him I would go somewhere else then. I got in my car and looked at my sticker and it said «SB 0÷20». When I got home I called the location on 120^th and Colorado and asked if «SB 0÷20» could be used on my car or would be dangerous for my car and he said it would not be dangerous at all for my car. I asked him what it stood for and he said «synthetic blend 0÷20». So either Grease Monkey is putting the wrong oil in my car or the manager at the 136^th and Colorado location was trying to take advantage of a female by herself. It would be great if someone could explain to me what I’m misunderstanding or what I’m getting wrong so that I know what oil I should be putting in my car or what is allowed to be put in my car. I use Grease Monkey because they were the least expensive for the Synthetic Blend. The manager should have at least come out and talked to me rather then acting like I didn’t know what I was talking about and not caring about my business. Please email me back at
(I will then email you my phone number). Thanks!

Love these guys! My son had an enormous intertube sled that we were unable to pump at the air station at King Soopers, so we headed over to Grease Monkey, and they pumped up his sled for free, saving the day :)
So incredibly kind and very much appreciated. This is why we continue our business there!

$ 80 for a straight-​up oil change? Not anymore…

This place is awsome!!! never do I have to worry about my vehicles. There very polite and do a great job.

These guys charge a fair price for their services. I’m visiting my mother-​in-​law this weekend and the CEL light came on in my MIL’s «backup car» — an 2001 Subaru that she keeps around for us to borrow when we are in town.
Since i work on my cars at home in CA, I realized that a quick way to figure out what was wrong was to stop by Autozone and have them pull the code with their OBD2 reader for free (at home, I would have just used my own). As I suspected, one of the O2 sensors was going out (upstream of the cat according to the code — OBD2 cars are nice like that). I know that even if I had cleared the code, the problem would eventually come back and my MIL would be at the mercy to dealing with it herself.
The sensor itself is fairly easy to access (not as easy as a 4cyl honda) but requires that you get at it from underneath the car. Since my MIL doesn’t even have a car jack/​stands, I wasn’t terribly excited about swapping it myself.
The car was due for an oil change anyway so I figured I’d look for a shop that was willing to charge me a fair amount for the incremental effort of swapping the upstream O2 sensor while they already were under the car for the oil change.
Unlike a few other shops i checked out, these guys offered a fair price on the phone — a lower price if they could do it from the oil pit and a slightly higher price if they needed to put it on the lift. Besides the standard upsell offers I’d expect from any oil and lube shop (better oil, etc) which I politely declined, they did the work and stuck to their price!
In comparison:
— Sears refused to install parts they didn’t buy themselves OR allow me to just get under their lift and swap the part myself. They also wanted to charge more for a «standard oil change» until I asked why their most basic «maintenance package» (the ones with various metal names platinum/​gold/​etc) was $ 5 cheaper AND included a free air filter. IMO, that’s shady.
— Service Street: immediately tried to discount my ability to read an OBD2 reader and wanted me to do pay them for a diagnostic first. When I stated that I’ll take the risk of swapping out a potentially unnecessary part myself and just asked them to quote me a labor price to swap out this O2 sensor, they immediately went to the shop book and quoted 1.5 hours @ $ 125/​hr. I laughed and hung up because even though I couldn’t swap this part out myself without some additional tools, it’s immediately obvious from looking at the manifold that you didn’t need to unbolt the entire manifold to swap this stupid sensor.
Bottom Line: If you know what you need, these guys are a fair shop with friendly and polite staff. I’m sure I’ll be back.

Changed oil filter, air filter, vacuumed, checked tire pressure and tread, washed windows, gave a discount on a car wash, installed new wipers, checked my small oil leak, answered all my questions and showed me what they did. Amazing service, hard workers, honest prices. Reminded me that I could come back any time before my next oil change and get any fluids topped off. All for under $ 100. Oil change with all the above except car wash, air filter, and wiper blades costs $ 30 something.

They did a great job changing lights and installing my Hatch struts

I would not recommend getting your car washed at this location. After paying for the most expensive wash, my car is still dirty. They were gracious enough to offer me another wash code if I came in to claim it, but it’s hardly worth the hassle. I’ll find another location to wash my car that doesn’t require a second trip.
