With the Earth's temperature on the rise, it has become more and more important for people to do everything they can to curb their pollution habits.

Instructions

  1. 1

    Schedule your emissions test to take place on a nice day. The mechanic will need to run your vehicle for a greater period of time if it's cold or raining. The engine oil, coolant and the catalytic converter will need extra time to get warm.

  2. 2

    Test your battery to make sure it's in optimum working condition. If your battery's too weak, it can affect your fuel injector's performance and alter the outcome of your emissions test.

  3. 3

    Change your car's oil before scheduling an emissions test. If your oil is dirty, your car will create more harmful emissions.

  4. 4

    Fill your tank with premium gasoline. While it may cost a few cents more, premium gas is cleaner and more environmentally friendly.

  5. 5

    Circle the block for 20 minutes before parking in the mechanic's garage. This will give your vehicle plenty of time to warm up and burn off any emissions you don't want registered during the test.
