# PUC certificate tips: Ensure correct emission reading 2026-10-06T11:37:40+00:00 | Governance | Indian Opinion Desk Corroboration: 1 independent outlet Many petrol pumps are refusing fuel to vehicles without a valid Pollution Under Control (PUC) certificate, prompting a surge in people getting their vehicles tested. However, vehicles can fail the emission test or get an incorrect reading due to small oversights, wasting time and money. To get an accurate reading, drivers should ensure the engine is warm before the test. Running the vehicle for 5 to 10 kilometres brings the engine to its normal operating temperature, reducing harmful emissions. Regular servicing, including a clean air filter and fresh engine oil, also helps lower pollution levels. Additionally, checking for leaks in the silencer is recommended. Taking these precautions before reaching the PUC centre can help avoid a failed test and the need for a retest. ## Indian Opinion Analysis The surge in PUC certificate demand follows fuel pump enforcement, making a failed test costly in both time and money. The source offers practical steps, warming the engine, servicing the vehicle, and checking the silencer, that directly affect the pass rate. It leaves unresolved how widely these precautions are known or followed, especially among drivers who rely on older vehicles. The immediate takeaway for vehicle owners is to prepare before heading to the test centre. ## Coverage - amarujala.com Straightforward consumer advice with no political or ideological slant.
