The quality of gasoline is a question that excites absolutely all motorists. Unfortunately, not at every gas station you can find high -quality gasoline. But there are several ways to help you figure out how high -quality fuel.
1
The first method will help determine whether gasoline contains various impurities. These impurities can negatively affect the fuel system of the vehicle. Only a sheet of white paper will be required. Dright gasoline on a leaf and wait for evaporation. After drying, the sheet should remain perfectly white. If a fat spot or a spot with some incomprehensible shade remains at the place of evaporation, then this gasoline contains harmful impurities.

The speedy wear of the engine causes the presence of fuel resins. To check the share of the resin content, you can conduct a small experiment. Drop the gasoline on the glass and set fire. It will burn quickly, and circles will remain on the glass. If circles are white, then the content of resins is normal. If brown or yellowish stains remain, then the capacity of the resins exceeds the norm.

Next, a gasoline check should be checked. It is enough to pour it into a transparent can. Ideally, gasoline should be transparent without any impurities and have a yellow shade on the lumen. In another vessel, you need to make a solution of water with potassium permanganate. Add a couple of drops of this solution to a can of combustible. If it is tinted, then there is a probability that water includes water.

The next testing method is to drip gas on the skin or substitute a finger under the stream. The fuel should quickly evaporate, leaving no trace. A fat stain on the skin indicates the non -compliance of gasoline norm.

And the easiest way to determine the quality of gasoline by smell. Just do not immediately open the canister and completely draw into yourself the smell. It is unsafe for health. It is enough to pour a little gasoline into a small container, move 20 cm from the face and lure the smell with your hand in your direction. Good gasoline will never be an admixture of the smell of hydrogen sulfide. It is easier to say that fuel should not resemble the smell of rotten eggs.
Thus, to evaluate the quality of gasoline yourself is possible. Only with all experiments it is necessary to observe safety precautions.
