Petrol Quality Check: 5 Easy Ways to Detect Adulterated Fuel at Petrol Pumps
Petrol quality check is an important step that every vehicle owner should know to avoid problems caused by poor-quality or adulterated fuel. Unclean petrol can affect engine performance, increase maintenance costs, and reduce the efficiency of your vehicle. Before refuelling, customers can use simple methods like checking the fuel density, verifying the quantity through a 5-litre test, and ensuring the fuel meter starts from a zero reading. Being aware of these checks can help you make sure that you are getting the right quality and quantity of petrol.
How to Identify Good Quality Petrol Before Refuelling
Pure petrol usually has a clear or slightly transparent appearance along with a distinct petrol smell. If the fuel looks unusually dark, cloudy, or has a strange odour, it may indicate possible contamination or adulteration.
Before starting the fuel filling process, always check that the petrol dispensing machine shows “Zero”. This ensures that the meter has been reset and you are paying only for the fuel being dispensed during your transaction.
What Is a Petrol Density Test and Why Is It Important?
A petrol density test is one of the most reliable methods to check fuel quality at a petrol pump. Petrol stations are required to have density measuring equipment and charts that help compare the actual fuel density with the standard range.
At a temperature of 15°C, the normal density of petrol generally falls between 720 and 775 kilograms per cubic metre (kg/m³) or 0.720 and 0.775 grams per millilitre (g/ml). If the density reading is significantly outside this range, it may indicate a quality issue or possible adulteration.
Customers who have doubts about the fuel quality can request the petrol pump staff to conduct a density test and compare the results with the available density chart.
How Is the Petrol Density Test Conducted?
The density test is performed using specialised measuring equipment available at petrol pumps. The attendant collects a sample of petrol and measures its density using the approved device.
The reading is then matched with the standard density range mentioned on the petrol pump’s density chart. If the value does not match the expected range, customers can ask for further investigation or raise a complaint with the concerned authorities.
How to Verify Petrol Quantity Using the 5-Litre Test
Apart from fuel quality, customers also have the right to check whether they are receiving the correct quantity of petrol. The 5-litre measure test is a simple way to verify the accuracy of the dispensing machine.
Petrol pumps keep a certified 5-litre measuring container for this purpose. During the test:
