Recently, many motorists are switching to diesel fuel, the quality of which affects the durability and reliability of the engine. Most of these people are faced with the problem of choosing this type of fuel, which, unfortunately, is often not of the best quality.
It is necessary
- - a sample of high-quality diesel fuel;
- - laboratory equipment.
Instructions
Step 1
To check the quality of purchased diesel fuel, you need to use the help of special laboratories. In the event that there are no such organizations in the vicinity, use a fairly simple method to compare the appearance. Buy the required diesel fuel from a gas station and pour it into a transparent container. Place a vessel with proven diesel fuel of excellent quality next to it and compare them. Low quality fuel will have a darker color, and sediment may also precipitate at the bottom of the vessel.
Step 2
In order to find out the exact composition and quality of the purchased diesel fuel, you need to undergo an official examination using the aforementioned laboratory equipment. Take a sample of purchased diesel fuel with you and head to the nearest laboratory. There, your sample will be checked for many parameters: the cetane number will be determined (the flammability index should be at least 45); analyze the viscosity and water content; calculate the sulfur content.
Step 3
Also, do not forget to check the temperature characteristics of diesel fuel in the laboratory. Usually this type of fuel is assigned one of three values: summer (ignition temperature - 62 ° C, solidification - -5 ° C); winter (ignition temperature - 40 ° C, solidification - -35 ° C); arctic (flash point - 35 ° C, solidification - -50 ° C). Be careful when using these types of fuels, as for profit many suppliers may sell "fuel" that is not suitable for natural conditions, which can be detrimental to the engine.
Step 4
To protect yourself from the use of low-quality diesel fuel, ask unverified sellers at gas stations for all the necessary documents confirming the quality of this type of oil product. Of course, this method does not provide a 100% guarantee that the fuel being poured meets all standards, but still this is a small protection, perhaps, it will save your engine.
