Don’t trust just the ‘zero’ at petrol pumps; here’s how you may still be overcharged
Only checking zero at petrol pump is not enough—learn how density meter and meter tricks can lead to fuel fraud and how to stay safe.
New Delhi (The Uttam Hindu): Whenever we visit a petrol pump to refill our vehicle, the staff usually asks us to check the meter reading ‘zero.’ Most people feel satisfied after seeing this and assume they are getting the correct amount of fuel. However, experts warn that focusing only on the zero reading can still leave customers vulnerable to hidden fraud.
Watch more than just the ‘zero’
Petrol pump frauds can happen in multiple ways, and many such incidents have surfaced on social media. The real trick often lies not in the zero reading but in the density value displayed on the machine. While attendants insist on showing the zero reading, they rarely point out the density meter, which is crucial for verifying fuel quality.
What is the density meter and why it matters
The density meter indicates the purity of petrol or diesel being dispensed. It helps determine whether the fuel is adulterated. Government standards specify that petrol density should range between 720–775 kg/m³, while diesel density should be between 810–845 kg/m³. If the reading falls outside this range, it may indicate adulteration, which can harm your vehicle’s engine and reduce fuel efficiency.
Check for meter ‘jumping’
Another important sign of possible fraud is abnormal meter behavior. If the meter jumps suddenly from zero to a higher value like 10 instead of gradually increasing (1, 2, 3, etc.), it could indicate tampering. A properly functioning machine should increase steadily from zero.
Be cautious during panic buying
Amid global tensions, especially involving regions like the Strait of Hormuz, concerns about fuel supply have led to panic buying in some areas. Although authorities have assured that there is no shortage of fuel, such situations can increase the risk of fraud at petrol pumps.
Conclusion
To avoid being cheated, always check not just the zero reading but also the density meter and the behavior of the dispensing unit. Staying alert can help protect both your money and your vehicle.
