Oil FilterHigh performance dual stage oil filter

If you want an eco-friendly oil change, the first step is to have the right filter. Our 2nd filter, microfilter, strains 10X more than conventional filters on the market, keeping your oil clean longer—increase your fuel economy; decrease your oil use!


Motor OilMotor oil

Get a green oil change and really give our planet some love! We primarily use a re-refined synthetic blend oil and recycle all used oil to create a closed-loop system with no waste.


Tire Source™Tire Source™

Got tread? Green Garage™ and Tire Source™ have joined forces in Boulder to deliver the best values and brands in tires.


Nitrogen tire fill

We know it seems so simple, but it really makes a difference and is a great way to improve your fuel economy. See, nitrogen is a bigger molecule than oxygen, so it leaks out of your tires at a slower rate. This gives you up to 5 percent better fuel economy! Questions? Just ask any of our Smileage experts.


CoolantMaximum performance antifreeze-coolant

This coolant is made from re-refined ethylene glycol. We also offer propylene glycol, which means better heat transfer, higher viscosity and lower toxicity. More Smileage for your car, more love for the environment.


Wheel WeightLead-free wheel weights

Lead exposure is a health concern. It’s crazy that we’d continue using lead wheel weights and allow them to just drop off into our streets. We think steel weights are a better idea. Safer, and just flat out better.



Routine Maintenance

Our maintenance schedule includes a green oil change every 30,000 miles or 2 years, with just an oil filter change every 7,500 miles or 6 months. On top of that, we perform our 53-point inspection. Our mission is to make your car last as long as possible.


Emergency Repair

Whether you’re broken down or it’s just that sound you know is trouble, our full service garage has the knowledge, experience and car parts Boulder and Denver drivers need to get back on the road.


Green it up! It’s time to save you some money, time and the planet all at once. Services like our eco-friendly oil change or our lead-free wheel weights will have your car running like a champ and Mother Earth will thank you.
