How to improve emission test results of your car?

We urge you not to take this as a cheat to pass the emission test, but take it as a small and quick pamper for your car.

- Replace the engine oil before going for the emission test. For old or even the high mileage car going for thicker oils do help.

- Change or tweak the spark plug and clean the air filter. However, a total tuning up could help a lot if the car is old.

- Flush off the fuel injector.

And just before the emission test, adjust the tyre pressure to optimum and have premium unleaded petrol/gas/diesel fuel the car. After fueling, go for a small ride to help clean the spark plug. Also have the engine warm before the test.
