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


Which petrol stations in Latvia have better fuel and what it will come from and which indicators are generally good fuel? He explained this "Prohibited Technique" by transferring fuel samples taken to analyze several Latvian, British, German and Polish fuel stations. The broadcast also found that most of the fuels in the Latvian market came from the Mažeikiai plant, and also consulted on how motorists can check the quality of fuel.

In order for analyzes to be the same, the program team used 5 liter cans, with the cheapest fuel available at a specific petrol station – a 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, it has about 70 filling stations, which will be taken mainly by the Lukoil company, which is currently the official property of the Austrian Amic company.
  • Neste station in Riga, Krastā street. Neste is a Finnish energy company, and there are also around 70 stations filled in Latvia.
  • Circle K (formerly "Statoil" station). The network is currently owned by a Canadian company, with about 80 stations in Latvia, and is the largest fuel retailer.
  • To make the picture even more complete, the smuggling is called or fuel from Russia, which is often imported in Latvia is legally and goes into secondary market.

Samples taken abroad:

  • In the UK, "British Petrolium" at Newmarket Station, near Cambridge.
  • In Germany, "Krimphoff & Schulte" Y Rhine, near the border of the Netherlands.
  • Germany, Berlin, Aral Britain's largest petroleum station and network in Germany.
  • In Poland, "British Petrolium" station near the town of Ccel, between Poznan and the border with Germany.
  • In Poland "Lotos" the station to the town of Kosice, between Poznan and Warsaw.

Samples with the specific method were checked by the State Revenue Service Customs Revenue Service, they were rapid tests on basic fuel indicators, determined by European Union legislation and Latvian law. The test gives first insight, it is a widely used and widely used method, because detailed sample analysis costs about ten times more expensive.

Gasoline grade 95

GER (Krimphoff) 1.52 euros / l

LAT (Circle K) 1.32 euros / l

Test gasoline after research number octane, and then the name of the petrol type – be it 95 or 98, for example. In each of the samples tested, everything is in order, with one German sample with the maximum octane number, and the 98th mark is likely to be filling

"In popular science, the octane number of research is found in stable conditions. Well, it could be a motor when it is dormant when nothing changes to it, simply drive the engine quietly and set the boundary when the cut started, "Kaspars Korotkijs, expert of the old habits explained.

Indicator – gasoline density. The gasoline is in Germany, Great Britain, Poland and Latvia – "Neste" – a little better.

"If the density is higher, gasoline may have a higher heat of combustion, so that there is more energy in one liter of gasoline, but the engine has to design & Specifically for petrol, so it is still within the limits of the information. If the density is too high then other parameters will suffer there and it will not be good for the engine , "Korotkijs explained.

Variety of hydrocarbons. All fuels are one hydrocarbon compound, but each has different features – one more energy efficient, one is smaller. Bensen, toluen, olefines – these types of hydrocarbons have a very high octane value, which means that they are very good, but are considered harmful to health and so their amount in fuel is limited .

Aromatic hydrocarbonAccording to the regulations of the Latvia Government, it should not exceed the 35 point limit, the highest olefin content is 18. The final value for benzene, the most damaging of these substances is 1. The & # 39; r all samples correspond to these limits. But, for example, the proportion of benzene is higher in the "Circle K" and "Viadä" gasoline. There are more olefins and more in fuel Nestes compared to German, British and Polish tanks.

Oxygenadau, ethers, ethanol – These substances also increase octane numbers, but have another disadvantage when petroleum contains many compounds that contain oxygen that's oxygen, causing gasoline combustion heating to decrease, and thus its efficiency.

"Ethanol has an unpleasant feature that it absorbs water vapor, which results in the release of water that can abolish gasoline in gasoline. And water in connection with metal parts can cause corrosion," Korotkijs explained.

Ethanol scores are very similar, with less obvious oxygeners for Neste.

Include oxygen. The norm states that it should not exceed 2.7%, and that this norm is observed in each sample, the figures are very similar – Nestei is a little better.

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

Diesel fuel analyzes

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

Diesel fuel prices "Prohibited Approach"

GBR (BP) € 1.59 / l

GER (Krimphoff) EUR 1.34 / l

GER (Aral) 1.28 euros / l

POL (BP) 1.27 Euro / l

POL (Lotus) 1.26 Euro / l

LAT (Cycle K) 1,25 euros / l

LAT (Viada) 1.24 Euro / l

LAT (Neste) 1.23 Euro / l

"The essence of the cetane number is the ability to burn silently. If the cetane number is low, the engine will rise. There is a holding between the moment of the moment and the combustion of the fuel. , the fuel burns faster, faster, the engine raises loads, increases the wear when it is used for a long time. If the cetane number is higher , the engine is silent, it turns out, does not flush, "explained the laboratory representative.

Above the cetane number, the lower fuel consumption.

The best of a UK diesel, both models from Poland and Neste's fuel, but the worst diesel fuel of Latvia from Viada and Circle-K was purchased.

In addition, the figure of 50.7 and 50.2 is lower than the restrictions of the government regulations of Latvia and the standard of the European Union, which is 51.

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

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

The lab representative explains that these figures are in error, and if the error is explained in favor of the company, then 51 would be achieved.

But, for example, the British cetelian number is already close to the 55-point mark, which, in turn, according to Nestes, had previously been for diesel fuel. There are 51 points more than Russia's fuel.

By seeking the results of the "Circle K" analysis itself, it appears that the cetane number is not measured at the stations, but it does it in the base fuel. The company sent analyzes of the Estonia "Analiit" laboratory to the program, which indicates that the specific diesel number has a 5,55 cetane ratio.

Fuel density. Density indicates a specific mass of liter of diesel with higher density due to higher calorific values, Correctry explained.

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

Aromatic hydrocarbons. It is not desirable for diesel fuel because weight is needed on the lighter burning. Therefore, it is not desirable for a diesel engine, and also from an ecological perspective – if its fuel is incomplete, the aroma is poisonous or even carcinogenic. .

Best Nestei creators, British British Petrolium and Polish diesel "Lotos". The worst is Viada, Circle K and Diesel from Russia.

PNA – polycyclic aromatic hydrocarbons. He has a particularly heavy smell. According to the Latvian norm, the limit of eight points can not be passed.

Model boundaries are respected everywhere, but the worst indicators are the German diesel "Arala" and "Viadas", the best indicators – "British Petroleum", "Neste", British and Polish.

FAME – abbreviation of fatty acid methyl acid, commonly known as biodiesel. Latvia usually uses either an ester of methyl rapeseed, maybe some other vegetable oil, but in Latvia, it usually has rape oil. A compulsory biofuel additive that adds to diesel, at least for a summer diesel. Usually in Latvia they are 4.5% – 5%.

"Viada" and "Circle K" can also be seen, for example, in other European countries, there is already a standard that the biodiesel share should be around 7%. But only Russia diesel and Nestes.

There are no mandatory standards of this kind in Russia, but in the case of Nestes, the other renewable resources are replaced by this part, the HVO fat oil has to hydrolide, which can be do but no analysis was taken, Neste himself explained. A diesel, which is produced by recycling waste, processing oils, oils, producing fuel that does not contain ponds.

Sulfur content – the less, the best. Permitted norm 10. All samples within the normal range. The best indicator for diesel "Lotos" Polish and "Neste", the worst German "Krimhoff".

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

There are good overall figures for UK fuel, but our "Cylch K" and "Viadas" figures are losing in this competition.

What can bad fuel mean?

Owners of Andris Selevičs "Varāns" car center told the program that fuel quality affects juice filters, oil filters, fuel filters.

But drivers can judge the quality of fuel after fuel consumption, "because many diesel cars have failed to blow and only because the fuel does not burn" if the fuel is good, " the machine is running on and the fuel consumption is low if the fuel is low quality – difficult to start, eat big ".

If the fuel does not burn, it's lightly developed, they're all "" illuminated, and so it's not & # 39; The car goes as it should, "Selevič explained. If the collector is "going away", the sky breaks twice less than the need and the car does not go away.

Diesel machines are much more efficient in fuel or petrol, but diesel is much more common in Latvia. Diesel fuel can cause the fuel injector to fall due to the quality of poor fuel.

The doorfighter's advice is to test the quality of the fuel by marking its use by changing different companies.

Where is the fuel coming, which can be filled by Latvia filling stations?

Latvia's most popular sellers say that fuel is taken:

  • Circle K – Plant Orlen in Lithuania, Mažeikiai.
  • Viada – Org Plant in Lithuania, Mažeikiai.
  • Napflies – Orlen Plant in Lithuania, Mažeikiai.
  • "Virši A" factory – "Orlen" in Lithuania, Mažeikiai.
  • "A Starte" – "Orlen" factories in Lithuania, Mažeikiai.
  • "Kool" – "Orlen" factories in Lithuania, Mažeikiai.
  • Shell does not respond within three days.
  • Neste – the fuel comes from Finland.

The savory oil in Mažeikiai is the Soviet heritage that recreates Russian crude oil through Belarus to the needs of the Baltic States. In 2006, it was acquired by a Polish company PKN Orlen, who also owns Orinal Transshipment of Butinge Oil in Lithuania, that oil products can be exported further by ships and also a pipe that connects Polock with the plant and then with the Butinge end.

Alvis Ērglis, Sales Director of Circle K Latvia, said he had bought fuel from Orlen's plant, by buying each year and choosing the best supplier.

"In our case, we can set our parameters for the manufacturer, asking us to produce a concrete fuel for us. And here, I really want to dismiss the myth that all the fuel in the whole market comes from one barrel , a tank. Well, it's not quite safe, "said Eagle.

"Our requirements are based on a standard set by the European Union, which is separate for diesel and petrol. [..] We also add fuel additives that further increase this quality and improve performance and car economy, "said Eagle.

Meanwhile, Neste Latvia's board member, Armands Beiziik's Retail Manager, said Neste was a fuel oil refinery with 70 years experience and that all the fuels that came to Latvia come from Finland's factories.

The fuel is transported from Finland by ships, stored in the terminal in Freeport from Riga and then distributed further. The fuel is supplied without additives, additives that improve the quality of fuel, are added to the terminal at the moment when the fuel carrier is charged and is driven out of & # 39 ; r terminal.
