Ice, snow, poor traction – this is one of the most frustrating factors that await our motorists in the winter. Especially the bad cases of poor engine start. This problem can be triggered by a few things – a malfunction of the fuel system components or freezing of the fuel. So in today's article, we'll look at how useful additives for diesel fuel, and test products the most famous manufacturers.
Let's Start with the characteristics of the product. Additives for diesel fuel designed to prevent solidification of the fuel at low temperatures. When using these depressants properties of diesel fuel are significantly improved. In other words, the additive makes the fuel “obedient” in the winter time.
As practice shows, antigel able to increase the chance of a reliable engine starting at times. This allows you to stop the disruption of the motor and realize a quick heating it for further movement of the car.
Why is this type of fuel freezes in the cold season? The whole crux of the problem lies in the paraffins, which, when the temperature of the air begin to turn into dense crystals. At high concentrations, the fuel begins to change color (note in the photo below), while its viscosity increases.
If the temperature continues to fall and further, in the fuel formed small clumps of wax. In size they are not able to go through the extract filter, but because its composition simply beat him. Thus, due to the large amount of paraffins in the fuel supply to the combustion chamber is blocked. Running the engine in this case is impossible.

It is also Worth noting such factors as PTF (the limiting temperature of filterability of fuel). She is defining a rate at which diesel fuel loses its original properties, even begins to crystallize. Experts recommend buying at filling stations that fuel, which increased PTF by 5-10 degrees Celsius below the average temperature in your area in the winter.
But what if in fact the fuel freezes before this at the gas station in time (at a lower temperature)? Only one way out – “thaw” fuel, filling a tank of diesel additives. Reviews say that this product significantly lowers the PTF fuel, so that it is not clogged in the filter at startup.
As we said earlier, change the color of the fluid says that she has been exposed to low temperatures. That is, the fuel began to form small crystals of paraffin. However, this does not mean that diesel fuel is more muddy unusable. Importantly for winter fuel-not an indicator of transparency and good pumpability in all parts of the fuel system, including through fine filters. Therefore, always pay attention to the PTF fuel, and not to its color. By the way, sometimes even after use of anthela diesel fuel is not fully transparent, with the engine running stably and which is not.
Recently on the shelves of local stores began to appear entirely Felix. This additive was developed by the specialists of the Russian company «Tosol-Sintez”. During produced test new showed good results, providing to prevent freezing of the fuel at temperatures down to -28 degrees Celsius. But, as noted reviews, antigel for diesel fuel grade "Felix" is able to decrease the PTF as much as -40 degrees. Thus, the car with proper use of anthela of the brand may wind up with a half-turn, even in the most severe climatic conditions.
This is a German antigel for diesel fuel. The test showed that this additive as well to cope with the paraffins in diesel fuel, like its domestic analogue "Felix". However, the Germans managed to beat it only by 1 degree. Judging by the results, antigel diesel Mannol able to start the car in the winter at a temperature of -29 degrees Celsius. Another plus “mandala” is the possibility of precise dosage of the liquid (thanks to the bottle with a measuring Cup).
The Test showed that the additives “Expert” is able not only to significantly increase the temperature limit of filterability of fuel (9 points), but also to improve the lubricating properties. Thus, “Expert” gives you the ability to start the car in winter when the ambient temperature is minus 29 degrees Celsius. But that's not all the advantages of Russian additives. According to reviews, antigel for diesel fuel Expert has a very convenient bottle with a narrow neck, so that it can be poured into the tanks with small diameter neck.Especially important this factor is for owners of modern cars, the manufacturers that make very small filler hole, designed for pistols with a thin nose.
This tool produces a company of American origin. It should say that the additive in butter of the diesel engine and entirely brand Gunk long ago come to Russia and have proved themselves to be very good side. How does this antigel diesel? Reviews say that, unlike the previous additive Gunk is able to increase the rate of PTF by as much as 13 units. Thus, this product can turn even the summer diesel fuel in winter, which is not kristallizuetsya and in the dead of winter. However, in contrast to the Russian “Expert”, the Gunk had not a high lubricating abilities.
The queue a German additive to diesel fuel Castrol. Alas, the results of the studies did not meet the famous German quality. Yes, the freezing temperature of diesel fuel additives "Castrol" good job. However, the main indicator of PTF – no. After using antigel fuel becomes unusable already at -20 degrees. Also one disadvantage of this additive is lack of instruction in Russian. The only plus "Castrol" is a convenient bottle, which is also equipped with measuring strips for a more accurate dosage. As the reviews say, antigel for diesel fuel from the company "Castrol" justifies its price, and therefore to award him the lead we can't.
Antigel from Liqui Moly has been for many years considered one of the best among those imported, imported from abroad. Judging by the results of the tests, this additive is able to provide successful motor starting, even under a 32-degree frost. In addition, “Disrupt the Moth” scored excellent lubricating properties. This increases the resource parts of the fuel system, including filters and pump. I must say, the German firm Liqui Moly is significantly ahead of their counterparts by Castrol in terms of the protection of fuel from the formation of paraffin sediment. By the way, the firm “LIQUI Moly" makes a good additive in the diesel oil, which, depending on the purpose, provide the lubricating or cleansing properties to the engine. In the latter case, they perfectly prevent the coking of the cylinders, which is a consequence of the use of substandard and sometimes messy fuel.
Test of diesel additives showed that the majority of the samples tested anthela have withstood the test cold. Depressants have significantly improved low-temperature quality and the viscosity of the fuel. Thus, the rate of limiting temperature of filterability summer grade fuel has been lowered to values of -20 to -29 degrees Celsius (depending on brand of product). On the basis of these indications, we can safely say that if the index of filterability of diesel fuel corresponds to the winter grade (that is, -25 OC), the antigel would lower this value to the following temperatures:
In addition to improving viscosity, some samples of anthela was noticeably different for its lubricating abilities. Improving the quality of the lubricant reduces wear of the fuel equipment, which greatly prolongs its service life. Thus, it is best provided lubricating properties of engine additives “Disrupt the Moth" (7.5 per cent) and “Expert” (3.7 percent). According to reviews, antigel for diesel fuel brand Liqui Moly is one of the best options for the driver. This additive has the most optimal ratio of price to quality, for which she deserves the leading place in our test.
It Should be noted that the above figures the limiting filterability of fuel can be achieved only if the driver observe the proper dosage and the technology of adding the petrochemical industry. First and foremost you need to understand that each manufacturer requires a mix antigel in a certain proportion. It is not necessary to follow the principle of “bigger is better”. Making the overdose, you only exacerbate the situation – from increasing the amount of the additive added to tank the PTF index will not increase. That is, in this case, you're just wasting money. By the way, the proportionality of adding antigel in the fuel can vary significantly. The dosage may be 30 ml per 100 liters of fuel, and 300 milliliters of the same volume of fuel. Therefore, always pay attention to the instructions (it is often available on the label of the vial).
In Addition to dosages should be followed the temperature. You must remember that the antigel is added to the tank just in case, if the ambient temperature is not less than 0 degrees Celsius. Otherwise, the use of the additive will not lead toanticipated impact. This rule applies to both the fuel and the bottle of additive. Last, it is desirable to add immediately after refilling without disturbing the aspect ratio.
When working with similar petrochemicals should not forget about the safety rules. It is necessary to reduce the likelihood of additive on the surface of the skin. It is recommended to use special rubber gloves. Or at least don't touch the finger of the neck of the bottle. If antigel has been spilled on the hand, it should be cleaned with water with soap. In any case do not expose the gel in the eye area (this can happen by careless opening of the bottle).
When buying, pay attention to the shelf life of the product. He must not end earlier than six months after the purchase. Quality additive has a shelf life of 36 months i.e. 3 years. Keep antigel is recommended in the closed state in a dark place, carefully protected from exposure to direct sunlight. Please note that at the temperature above 45 degrees the properties of the additive will be lost. Therefore, keep it should be in a cool place.
So, we have learned, what has reviews antigel for diesel fuel from different manufacturers and also found out how important is this additive to the car in the winter time. Paraffin – the main enemy of the motorist in the winter. To remove it is impossible, but to prevent it “multiplication” is quite real. It's enough to buy antigel and pour it into the tank, adhering to the correct proportion and temperature. Finally, we note that the purchase be products of known manufacturers. Do not skimp on additives, trusting the unknown producers of goods without labels or stickers. Poor quality antigel capable of negatively influencing the operation of the fuel system of a vehicle, which can lead to costly repairs.
