How to check the quality of automobile fuel?
The quality of automobile fuel can be checked using the following methods:
👀 Visual inspection. We pay attention, first of all, to the color and transparency of the fuel. Gasoline should be light yellow or colorless and diesel fuel is light yellow or greenish. The fuel must be transparent, without mechanical impurities or water (stratified drops, turbidity). Of course, determining quality “by eye” is not enough.
🧪 Using express tests. There are special strips of cardboard on which a polymer composite material is applied that changes color when interaction with metals. The principle of their operation is that if you touch the filling nozzle to such a strip, its color will change depending on the content of certain substances in the fuel. Intensity staining may indicate an excessive content of sulfur, nitrogen-containing compounds, the presence of lead or iron. But the use of express tests makes it possible to assess the quality of gasoline or diesel rather superficially, legally The result of the study will not be valid, and the sensitivity of the test may fail.
🚘 Using sensors. A special sensor that can be installed on a car's fuel system can measure certain parameters fuels such as density, viscosity, water content and others. The principle of its operation is based on various light refractive index of fuel depending on its quality. However, when installing such a sensor, you will need prepare the fuel system and carry out certain manipulations with it. Yes, and the sensor itself must pass periodic maintenance to ensure its performance remains reliable.
🔬 Fuel analysis in the laboratory ⚗️. The most reliable method, which involves a comprehensive study of the fuel for its quality. It allows you to get accurate data without prior intervention in the fuel system and before purchasing a significant volume of petroleum products. At the same time, a study is carried out of the fractional composition, content of water, methanol, sulfates and other substances in the fuel. Thanks to the conclusions issued by the laboratory, it is possible to compare samples from different suppliers.
It is recommended to use fuel only from reliable suppliers, monitor its storage and, if necessary, carry out quality checks in laboratory conditions. This will ensure efficient and safe operation car, will eliminate the risk of purchasing low-quality petroleum products, and will protect you from financial costs associated with equipment repair.
