How to Pass Your Smog Test with Success

There are several factors that go into an emissions test, which is a requirement in Las Vegas, NV in order to keep our breathing air fresh and clean. If you are concerned about passing your upcoming smog check, you’ve come to the right place. Below is a list of things you can do to make sure your car, SUV, or truck passes with stripes and stars!

Fix Your Check Engine Light

This warning light results in an immediate failure of the smog check. If your check engine light is illuminated, you should have it diagnosed and repaired if you want your car to be legal to drive. Feel free to bring your car to Asian Imports for diagnostics.

Take It for a Run 

In some cases, the catalytic converter may not get hot enough to perform its job effectively. Before the test, we recommend taking your car for a 15+ minute drive before the test to ensure accurate results.

Get an Oil Change

Clean oil in your engine is always good, no matter the occasion. When it comes to fresh oil for smog testing, it will ensure that extra pollutants are emitted. 

Make Sure Tires Are Properly Inflated

While your vehicle gets examined during the smog test, your tires will likely be placed on rollers and run at high speeds so that their emissions can get measured. If your tires aren’t properly inflated, your engine may have to overwork to compensate.

Use a Fuel Additive

A fuel additive can come in handy to cleanse the fuel system. This is especially recommended for older vehicles with lower fuel economy.


Ultimately, the best way to be prep for a smog test is to keep up with your regular auto maintenance throughout the year. If your vehicle is healthy, you won’t have anything to worry about when it comes to vehicle emissions. We invite you to Asian Imports for your next smog test today!
