Tips to pass the car emissions testing

In the United States it is required that the car passes emissions inspection. The car cannot be legally driven on the road until it passes the testing. We bring you some tips and tricks to help you pass the emissions testing.

Check engine light

If the check engine light is on, your car will not be able to pass the testing. The light may disappear after a few days, but if it persists you will have to take care of the cause in order to pass the test.

Oil change

If the engine oil is old, it may cause an increase in CO emissions.

Fuel

Get the best petrol you can get. More octane means better burning process. This should increase your car’s chances to pass the emissions testing.

Spark plugs

We suggest that you replace your spark plugs too. New is better, as simple as that.

Air filter

You should change it prior to testing. If it’s dirty it can cause increased levels of CO emissions as well. Same as above, just get a new one.

Gas cap

The gas cap should have no cracks and it must be tightly closed. You will hear a clicking sound once the cap is properly tightened.

Tire pressure

If the testing includes dynamometer you should make sure the car’s tires are inflated properly. The proper tire pressure will result in a more constant performance.

Drive around a little bit first

Don’t go in while the car’s engine is still cold. Warm up the engine first. This helps optimise engine performance resulting in better fuel burning and more efficient performance.

 

These are just some of the tips that might help you get your car ready to meet the requirements and pass the emissions testing. If you need any more information about requirements for your area, you can find it here. Just select your state and proceed.
