Which loading stations have better fuel quality / Article / LSM.LV

What gas stations in Latvia have better fuel from where it comes from and what are the usually good fuel indicators? The "Forbidden Technique" explained this by transferring the fuel samples taken for analysis to several Latvian and British, German and Polish fuel stations. The issue also found that most of the fuel in the Latvian market came from the Mažeikiai plant and it was also consulted on how drivers can verify the quality of fuels.

For the analysis to be the same, the program team used 5 liter cans, with the cheapest fuel available at a given gas station – summer diesel and 95 pounds of gasoline.

Samples taken in Latvia:

  • "Viada" the station in Riga, Maskavas street. The company now claims to be a new one in Latvia, has about 70 freight stations, which are mainly taken from the Lukoil company, which is currently the official property of the Austrian company Amic.
  • In this station in Riga, Krastā street. This is a Finnish power company and there are also about 70 freight stations in Latvia.
  • Circle K (previously "Statoil") station. The network currently has a Canadian company, with approximately 80 stations in Latvia, and is the largest distributor of fuel.
  • To make the image even more complete, the so-called smuggling or fuel from Russia, which is often legally imported into Latvia and enters the secondary market.

Samples taken abroad:

  • In the United Kingdom, "British Petrolium" at Newmarket Station, near Cambridge.
  • In Germany, "Krimphoff & Schulte" Rhine Station, near the border with the Netherlands.
  • Germany, Berlin, Aral a British oil station and the largest network in Germany.
  • In Poland, "British Petrolium" station near the city of Chcel, between Poznan and the border with Germany.
  • In Poland "Lotos" the station to the town of Kosice, between Poznan and Warsaw.

Samples with the express method were verified by the State Income Tax Customs Service, which were rapid tests on the basic indicators of fuels, determined by European Union and Latvian legislation. The test gives a first perception, is a recognized and widely used method, because in-depth depth analysis costs about ten times more expensive.

Gasoline of degree 95

"Prohibited techniques" Gas sample prices

GER (Aral) 1.64 euros / l

GBR (BP) 1.54 euros / l

GER (Krimphoff) 1.52 euros / l

LAT (Circle K) 1.32 euros / l

LAT (Widow) 1.31 euros / l

LAT (Neste) 1.30 euros / l

POL (BP) 1.29 euros / l

POL (Lotos) 1.28 euros / l

Proven gasoline after the octane number of the investigation, followed by the name of the type of gasoline, either 95 or 98, for example. In all proven samples, everything is in order, with a sample of Germany with the highest octane number and the number 98 mark is likely to be filled.

"In popular science, the octane number of research is obtained in static conditions. Well, it could be an engine when it is inactive when nothing changes to that, simply by taking the engine silently and setting the limit at which the detonation begins," Kaspars explained. Korotkijs.

Indicator – gasoline density. Gasoline in Germany, Great Britain, Poland and Latvia – "In this" – is a little better.

"If the density is higher, it is possible that gasoline has a higher combustion, so that in a liter of gasoline it will have more energy, but the engine is designed especially for gasoline, so it is again within the limits of intelligence. It's too high, other parameters will suffer there and it will not be good for the engine, "explained Korotkijs.

Various types of hydrocarbons. All the fuel is a unique compound of hydrocarbons, but each of them has different characteristics: one has more efficient sources of energy, one less. Benzene, toluene, olefins: these types of hydrocarbons have a very high octane value, which means that they are very good, but are considered harmful to health, and therefore their amount of fuel is limited.

Aromatic hydrocarbonAccording to the regulation of the Government of Latvia, it must not exceed the limit of 35 points, the maximum olefin content is 18. The limit value for benzene, which is most harmful to these substances, is 1. All samples correspond to these limits . But, for example, the proportion of benzene is greater in gasoline "Circle K" and "Viadä". There are more olefins and more are in these fuels compared to German, British and Polish fuels.

Oxygen, ethers, ethanol – These substances also increase the number of octanes, but they have another disadvantage when petrol contains many oxygen-containing compounds that are oxygen, which means that the heat of gasoline combustion decreases and hence its efficiency.

"Ethanol has such a nasty feature that it absorbs water vapor, which results in the release of water that dissolves in gasoline in gasoline. And water in contact with metal parts can cause corrosion," explained Korotkijs.

Ethanol scores are very similar, with oxygen and ethers less pronounced for Neste.

Oxygen content The standard stipulates that it must not exceed 2.7%, and this standard is observed in all samples, the figures are very similar: a little better is Nestei.

In general, all the samples are within the normal range, with no significant differences in the samples; In individual positions, Finland's "Nestes" fuel is better.

Analysis of diesel fuel

Diesel fuel is not an octane figure, but one cetane number

Sample prices of diesel fuel "Prohibited method"

GBR (BP) € 1.59 / l

GER (Krimphoff) 1.34 euros / l

GER (Aral) 1.28 euros / l

POL (BP) 1.27 euros / l

POL (Lotos) 1.26 euros / l

LAT (Circle K) 1.25 euros / l

LAT (Widow) 1.24 euros / l

LAT (Neste) 1.23 euros / l

"The essence of the cetane number is the ability to burn calmly. If the cetane number is low, the engine will work. There is a grip between momentum and combustion of fuel. As a result, fuel burns faster and more Fast, the engine increases the load, increases wear when used for a long time. If the cetane number is higher, the engine is quieter, it is crumbling and not plastering, "explained the representative of the laboratory.

The higher the number of cetane, the lower the fuel consumption.

The best diesel for the United Kingdom, both Polish models and Neste fuel, but the worst diesel purchased in Latvia from Viada and Circle-K.

In addition, the figure of 50.7 and 50.2 is below the limit of the rule of the government of Latvia and the norm of the European Union, which is 51.

Test results for all diesel fuel samples and their cetane number:

  • Lotos (Poland) 54.4
  • BP (United Kingdom) 54.1
  • BP (Poland) 53.9
  • Krimphoff (Germany) 53.5
  • In this (Latvia) 53.2
  • Diesel (Russia) 51.6
  • Aral (Germany) 51.1
  • Viada (Latvia) 50.7
  • Circle K (Latvia) 50.2

The representative of the laboratory explains that these figures are erroneous and, if the error is explained in favor of the company, 51 would be reached.

But, for example, the cetane number of British diesel is already approaching the 55-point mark, which, according to Nestes, was previously as a diesel fuel. 51 points outperform Russia's fuel.

When requesting the results of the analysis of the own "Circle K", it turns out that the number of cetane is not measured in the stations, but in the fuel base. The company sent analyzes of the Estonian laboratory "Analiit" to the program, which indicates that the specific diesel batch has a cetane ratio of 51.7.

Fuel density. The density indicates the specific mass of a liter of diesel that has a higher density due to higher calorific values, Correctry explained.

Here, the figures are similar, but the best is "Circle K", "Viada", the best – in German Krimhoff, but the differences are insignificant.

Aromatic hydrocarbons It is not desirable for diesel fuel because the aroma burns more and burns, which requires pressure. Therefore, a diesel engine is not desirable and also from an ecological point of view, if the fuel is burned incompletely, the aroma is toxic or even carcinogenic.

The best creators of Nestei, the British "British Petrolium" and the gasolés "Lotos". The worst are Viada, Circle K and Diesel of Russia.

NAP – Polycyclic aromatic hydrocarbons. It has a particularly heavy scent. According to Latvian law, the limit of eight points can not be exceeded.

The example borders are respected everywhere, but the worst indicators are German "Arala" and the "Viadas" gas pipeline, the best indicators: "In this", British and Polish "British Petrolium".

FAME – an abbreviation for fatty acid methyl ester, commonly known as biodiesel. Latvia normally uses the methyl esters of rapeseed oil, perhaps some other vegetable oil, but in Latvia it is usually rapeseed oil. It is a biofuel additive that is required to add to diesel fuel, at least for summer diesel. Usually in Latvia they are 4.5% – 5%.

You can also see "Viada" and "Circle K", it is clear that, for example, in other European countries there is already a standard that the participation of biodiesel should be 7%. But zero is Russia and these diesel.

There are no such mandatory rules in Russia, but in the case of Nestes, this part is replaced by other renewable resources, the abbreviated HVO, hydrolysed fatty oil, which can be done but no analysis has been carried out, explained Neste. It is diesel, which is produced by the recycling of waste, processing oils, oils, thus producing a fuel that does not contain puddles.

Sulfur content – The less, the better. Permissible rule 10. All samples within the normal range. The best indicator for Polish diesel "Lotos" and "In this", the worst German "Krimhoff."

The general conclusion is that, in terms of these creators, the best diesel of the Polish gas station "Lotos" is a high number of cetane, low aroma and low sulfur content similar to Latvian "Nesti".

Good global figures for UK fuel, but our own "Circle K" and "Viadas" figures are losing in this contest.

What does bad fuel mean?

The owners of the "Varāns" car center Andris Selevičs told the program that the quality of the fuel affects the filters of soot, oil filters, fuel filters.

But motorists can judge the quality of fuels after fuel consumption, "because many diesel cars are sucked with soot and that's just because the fuel does not burn" if the fuel is good, "the machine works and fuel consumption is Under low-quality fuel – difficult to start, high consumption ".

If the fuel does not burn, it develops calmly, "they illuminate everything we do, and so the car does not go as it should," explains Selevič. If the collector "disappears", the air is inflated twice less than necessary and the car does not go away.

Diesel engines are much more efficient than gasoline, but diesel is much more common in Latvia. Diesel fuel can cause the fuel injector to fall due to poor fuel quality.

The advice of the truck driver is to prove the quality of fuel by marking its consumption by changing several companies.

Where does the fuel come from, which can be covered by Latvian service stations?

The most popular Latvian freight traders report that they take fuel:

  • Circle K – Orlen plant in Lithuania, Mažeikiai.
  • Viada – Orlen plant in Lithuania, Mažeikiai.
  • Latvia Nafta – Orlen plant in Lithuania, Mažeikiai.
  • "Virši A" – "Orlen" factories in Lithuania, Mažeikiai.
  • "A Starte" – "Orlen" factories in Lithuania, Mažeikiai.
  • "Kool" – "Orlen" factories in Lithuania, Mažeikiai.
  • Shell does not respond within three days.
  • In this – the fuel comes from Finland.

The petroleum refinery in Mažeikiai is a Soviet patrimony that recycles crude oil from Russia to Belarus to the needs of the Baltic States. In 2006, it was acquired by the Polish company PKN Orlen, which also owns the Butinge oil transfer terminal in Lithuania, whereby petroleum products can be exported more by ships and also a gas pipeline linking Polock to the plant and logo with the Butinge Terminal.

Alvin Ērglis, sales director at Circle K Latvia, said that it was buying fuel from the Orlen plant, buying each year and choosing the best supplier.

"In our case, we are able to determine our parameters for the manufacturer, asking us to produce specific fuel for us. And here I really want to dispel the myth that all the fuel in the entire market comes from a barrel, a tank. completely safe, "said Eagle.

"Our requirements are based on a standard established by the European Union, which is separate for both diesel and gasoline. [..] We also add additives to improve fuel that further enhance this quality and improve both the performance and the economy of automobiles, "says Eagle.

Meanwhile, the CEO of Neste Latvia, commercial director Armands Beiziik, said that Neste is a petroleum refinery with 70 years of experience and that all of the fuel arriving in Latvia comes from the company's factories in Finland.

The fuel is shipped from Finland by ships, stored at the terminal in the Freeport of Riga and subsequently distributed. The fuel supplied without additives, additives that improve the quality of fuel, are added to the terminal at the moment the fuel carrier is loaded and left the terminal.
