No matter what you drive, you share a common need with thousands of other drivers on the road. That is the need to have a car that has a fresh, uplifting scent that makes your driving and the time you spend in your car a joy. Parents can understand when I talk about car interiors that have served as a diaper changing station, feeding table and let’s not even talk about kids getting sick in the car.
My saving grace has been essential oils and a car diffuser.
Drivers use different methods to try and achieve a nice scented interior and some of them are ingenious. For instance, we know of drivers who are quite adept at creating inspired, non-toxic air fresheners for their cars by using scented wax cubes in a jar that has holes on the top cover. When your car heats up, the wax melts releasing the scent.
Other drivers use a mixture baking soda and essential oils. The baking soda will absorb any bad odor and the essential oil will release a pleasant fragrance. I used to burn scented candles in my car when held up in traffic to combat the smell produced by the exhaust pipes.

Although some of these methods are ingenious and can kind of work, they tend to be messy and are palliative measures at best. Unfortunately, they fail to give you a proper, consistent fragrance that will last long. Besides, none of them is dispensed with ease and without spewing baking soda or hot wax all over your car seats.
A great solution to having a car whose interior smells fantastic lies in using a good car essential oil diffuser that will correctly dispense the amazing fragrances that essential oils have to offer.
A good quality car essential oil diffuser will allow you a myriad of fragrances to work with and varying potency levels. Dispensing these fragrances using a car essential oil diffuser is easy and far more effective than any self-made contraption a driver can conjure.

Why should you use oil diffuser in the car?
Manufactured scents are great but nothing can measure up to the diversity of the pleasant natural fragrances that essential oils can deliver. Apart from the fragrances essential oils also have therapeutic qualities. Using a diffuser allows you to harness all the benefits of the oils.
Here are some problems that can be alleviated by using car diffusers:

The air quality in a car is always suspected, especially when the car windows have been closed for some time. A car essential oil diffuser can help you purify the air by using essential oils like tea tree, basil, peppermint, eucalyptus or a blend of eucalyptus and lemon essential oils.
These fragrances naturally purify the air in your car, which lift your mood and keeps you alert.

If you have a sensitive throat, you can enjoy the natural health benefits of these herbs in the comfort of your car. Treatment does not stop once you leave the house and is nearby when the discomfort flares up at any point during the day.
Which oils can you use in a car diffuser?
A quality car essential oil diffuser is not restricted to a particular essential oil. This puts you at liberty to use any essential oil that has your favorite fragrance. However, these oils work best if they are soluble in water.
There are more than seventy natural single oil fragrances in addition to the countless blends. Depending on your mood or occasion you can use various fragrances that affect you differently.

You can always keep experimenting with different essential oil fragrances and different brands to discover even more fragrances that will quickly find their way into your list of favorites.
How to choose car oil diffuser?
Not all car oil diffusers are made equal. To choose one that allows a good range of options which will give you a chance to fully explore the extensive fragrances from essential oils, there are several questions to answer:
- How potent do you want the scent?
- How long do you want the diffusion session?
- Which oils do you want?
- Do you want an air humidifier and aroma diffuser in one or separated functions?
Once all this is decided you have several options to choose from. You can have a diffuser that can be plugged into your car’s cigarette lighter slot or one that is USB powered. Both are easy to use.
You simply put about 100 ml or the stated amount of water in the diffuser, drop in a few drops of your favorite essential oil and allow it to diffuse the oil.
A car diffuser with a rotating head is better as it allows you to point the header in the desired direction if there is any specific direction you want the scent focused on. Some car diffusers have a head that can rotate on the 180-degree axis.
It is important to note that most diffusers must be used when there is water inside and when the car is running to achieve optimal results.
