Easy Crafting with This DIY Essential Oil Car Diffuser

I drive a 1997 Toyota Previa. Randomly-opening side door, broken speedometer, non-functioning AC, and all, that thing is a rickety must bus. But don’t get me wrong, I love my car— it has a lot of… character. That being said, like it’s external appearance (its rounded shape and tan color resemble that of a potato), its internal smell holds its own sense of individuality, and I don’t mean that in a good way. 

There comes a day when all of us have to trade in that glorious new car smell for an everyday someone-may-have-spilled-ice-cream-in-here-two-months-ago vehicle scent. Or, if you’re like me, your car is 23 years old and has taken each of those years to compound its unique, questionable funk.  

As someone who drives a rolling piece of history, believe me when I say that essential oils can take care of your car’s stink. Using an essential oil diffuser in your car allows you to not only kick your car’s stink to the curb (ha, see what I did there), but to do so without any toxic junk that you’ll find in plenty big-brand “fragrance” ingredients. This essential oils car diffuser DIY recipe shows you how to make a diffuser for a car using 100% pure essential oils and your basic crafting skills

Hi! Katie here, certified aromatherapist and creator of our Essential Oil Recipe Box, which includes this recipe this month. 

I love that this recipe is so cute. It’s super easy to make and makes your car smell great. You can ride with style and smell great too!

Essential oil car diffuser

Blood Orange Essential Oil

When I first began learning about essential oils, I was immediately drawn to all things citrus simply because I couldn’t get over how rich, clean, and authentic citrus aromas are. Citrus essential oils also seem to have the unique ability to offer a strong, odor-fighting smell that never actually comes off as overwhelming. Blood Orange Essential Oil fits this description to a T with its fresh, sweet, and slightly tangy scent. 

Lemon Eucalyptus Essential Oil

Continuing on with the citrus theme, Lemon Eucalyptus Essential Oil mixes the uplifting and focus-boosting properties of eucalyptus with the deodorizing and clarity-improving nature of lemon. In other words, you road rage folks with stinky cars need not look any further. Capiche? 

Wool Felt Balls

You’ll drop your essential oils into these little felt balls so they can lock in and diffuse your oil’s aromas as you drive!


In order to make your wool felt balls into a cute little diffusing tassel/keychain, you’ll need some string or embroidery floss to link everything together. 

Accessories of Your Choice

When learning how to make an essential oil car diffuser, don’t forget about creativity! This car diffuser is pretty versatile when it comes to looks, so go ahead and make it your own! Here are some ideas to get you started:

  • Add some lettered beads to show off a car’s or driver’s name. 
  • Use embroidery floss to create a festive tassel at the end of your diffuser. 
  • Add colored beads that match your car. 
  • Add a shell to the end of your diffuser for a beachy look. 
  • Attach a mini clothes pin or paperclip that you could use to fasten your diffuser to your car’s AC vent. 
  • Add all sorts of beads and fabric flowers to make a floral, lei-style diffuser.

Mini Car Diffuser
