Preparing for an Emissions Check

  1. Understand your local laws
  2. Get a tune up

Local Law

Just like preparing for your high school physics exam, you need to know what you’re being tested on to make sure you pass.  Emissions programs vary by state so information should be available on your state’s website.  Some states do visual inspections for proper equipment, some analyze your exhaust gas content, and others simply run a diagnostic on your engine control module.  In some states, a check engine light being on is an automatic fail while others will let you slide through as long as the problem isn’t related to your vehicle’s emissions control systems.  Read up to make sure you don’t fail for a silly reason.

Get a Tune Up

As you read about in the article linked above tune ups are simple these days but are key to make sure your car is running well.  An inefficient motor will emit more pollutants than a properly operating one.  A clean air filter and new spark plugs will increase efficiency and clean oil will keep extra carbon out of the combustion chamber.  If your car needs to be put on a dynamometer for the test, make sure your suspension is in good shape, your tires are inflated and your cooling system is up for the challenge.

Premium Fuel

Premium fuel includes more detergents to keep things clean in your fuel system and will often burn more completely reducing emissions.  Also, premium fuel may allow some cars to increase timing slightly making them more efficient.  If you live in an area where oxygenated fuels are available, or fuels with ethynol added, definitely fill up with that!  lastly, add a bottle of BlueDevil Complete Fuel System Cleaner along with your fuel to help clean out your fuel system and increase the quality of the gasoline.  BlueDevil Complete Fuel System Cleaner is guaranteed to get your vehicle to pass the emissions test!

Drive Until Your Car is Warm

Your catalytic converter uses chemical reactions to clean pollutants from your exhaust gas.  These chemical reactions are the most efficient between 1300 and 1500 degrees so you need to drive long enough for things to get good and hot in your exhaust.  Also, your engine computer usually allows your car to run rich while it’s cold so a warm car will be running it’s best while your catalytic converter is working it’s best.

When you’re ready to pass your emission test, pick up BlueDevil Complete Fuel System Cleaner and stop worrying!
