1 / 8If you use a car or bike (Car-Bike) for travel, then a daily visit to the petrol pump is a must. You ask the staff at the petrol pump to fill your car-bike with petrol and while they are filling with petrol-diesel you ask them to check the meter for zero.2 / 8You also see zero on the meter and you are satisfied that your vehicle is fully fueled. But this matter does not end here. You just keep an eye on zero. But this is not enough to prevent you from being cheated. Here's how you can avoid this by being a little more vigilant.3 / 8If you think about it, cheating happens in ways you don't even notice. It is very important to pay attention to the density, not the fuel quantity section in meters.4 / 8The density meter in the petrol pump machine is directly related to the purity of your fuel. This figure has been fixed by the government. Actually, it can check the density of the petrol or diesel that you put in your car or bike is completely pure or not.5 / 8This shows that there is no adulteration in this. If you don't keep an eye on this, there is a chance that adulterated fuel will be pumped into your vehicle. This will not only waste your money but also damage your vehicle's engine.6 / 8Cheating is done by tampering with the standards set for density. If we want to understand density in clear words, it means density. After preparing a substance by mixing certain amount of ingredients, the quality of the substance is determined based on it, there is a slight difference in it.7 / 8The density of petrol is fixed at 730 to 800 kg per cubic meter. On the other hand, if we talk about diesel, the density is fixed at 830 to 900 kg per cubic meter.8 / 8Just as the rates of petrol and diesel are revised every morning, the density of petrol and diesel is also updated every morning by the petrol pump. In such a situation, if you want to avoid any kind of fraud in fuel, then Petro in future.
