1. Perform necessary maintenance – Tackle any necessary service items before having
your car tested, and check if your vehicle needs the following processes such as oil
changes and fuel and air filter changes.
2. Consider a tune-up – if you think your vehicle could use a tune-up before the emission
check, go right ahead. Assessing the condition of parts in the fuel and ignition system
such as gas caps and spark plugs. Replacing these serviceable parts can greatly
improve your engine’s running efficiency and your chances of passing the emissions
test.
3. Check your tires – During your vehicle inspection, the technician may have to drive your
car on what is called a ‘dynamometer’ as part of the testing process. Underinflated tires
can affect your emission check results because your vehicle may have a hard time
running and your engine pushes itself harder to reach the test requirement.
4. Warm up your engine – Spend some time driving your car at least 20 minutes right
before the test. Doing so will help ensure the engine is at the optimum temperature for
testing, engines that are warmer have a better chance of acing the test than those that
are cooler.
5. BONUS TIP: Before your emission test use Pertua Oil and Metal Treatment on
your next oil change. With its US-Patented DuraSyn Technology Pertua
thoroughly cleans the engine and lubricant System to reduce harmful emissions.
