Which gas stations have better fuel quality / article / LSM.LV


Which gas stations in Latvia have better fuel from where do they come from and which indicators are generally good fuel? The "Forbidden Technique" explains this with the transfer of fuel samples taken for analysis in several Latvian and British, German and Polish petrol stations. The show also revealed that most of the fuel in the Latvian market comes from the Mažeikiai factory, and it is also consulted on how drivers can check fuel quality.

To make the analysis the same, the program team used 5-liter cans, with the cheapest fuel at a given gas station – summer diesel and 95 pounds of gasoline.

Samples in Latvia:

  • "Viada" station in Riga, Maskavas street. The company now claims that the new one in Latvia has about 70 gas stations, which are mostly taken from Lukoil, which is currently officially owned by the Austrian company Amic.
  • Neste stations in Riga, Krasta. Neste is a Finnish energy company, and in Latvia there are about 70 gas stations.
  • Krug K (formerly "Statoil") cells. The network currently has a Canadian company with around 80 stations in Latvia and is the largest fuel store.
  • To make the painting complete, so-called smuggling or fuel from Russia, which is often imported into Latvia legally and enters the secondary market.

Samples abroad:

  • In the United Kingdom, "British Petroleum" at the Nevmarket station, near Cambridge.
  • In Germany, "Krimphoff & Schulte" Rhine station, near the border with the Netherlands.
  • Germany, Berlin, Aral The British Petrol station and the largest network in Germany.
  • In Poland, "British Petroleum" stations near the city of Chcel, between Poznan and the border with Germany.
  • In Poland "Lotos" station to the city of Kosice, between Poznan and Warsaw.

Samples with an express method were checked by the Customs Revenue Service of the State Revenue Service, they were quick tests on the basic fuel indicators, which were determined both in the European Union and in the legislation of Latvia. The test gives the first insight, it is a recognizable and widely used method, because a detailed sample analysis costs ten times more expensive.

Gasoline from the 95th grade

"Prohibited techniques" of petrol samples

GER (Aral) 1.64 euro / l

GBR (BP) 1.54 Euro / l

GER (Krimphoff) 1.52 euro / l

LAT (Circle K) 1.32 Euro / l

LAT (Viada) 1.31 Euro / l

LAT (Neste) 1.30 Euro / l

POL (BP) 1.29 Euro / l

POL (Lotos) 1,28 € / liter

Tested gasoline after the research octane number, and then the name of the gasoline type – be it 95 or 98. In all the tested samples everything is fine, with one sample from Germany with the highest octane number, and it is likely that the 98th mark will be filled.

"In popular science, the octane number of research is obtained under static conditions, well, it can be a motor when it's empty when nothing changes, simply by hitting the engine and setting the boundary on which the detonation begins," explained senior customs expert Kaspars Korotkijs.

Indicator – density of gasoline. Petrol in Germany, the UK, Poland and Latvia – "Neste" – is somewhat better.

"If the density is higher, it is possible that gasoline has a higher combustion heat, so in one liter of gasoline there will be more energy, but the engine is designed specifically for petrol, so it is back inside the intelligence limit. If the density is too high, then suffer and other parameters and it will not be good for the engine, "Korotkijs explained.

Different types of hydrocarbons. All fuels are individual hydrocarbon compounds, but each of them has different characteristics – one has more efficient energy sources, one less. Benzene, toluene, olefins – these types of hydrocarbons have a very high octane value, which means they are very good, but they are considered harmful to health and because of that, their amount of fuel is limited.

Aromatic hydrocarbonin accordance with the regulations of the Government of Latvia, must not exceed the limit of 35 points, the maximum content of olefins is 18. The benzene limit, which is the most harmful of these substances, is 1. All samples correspond to these limits. But, for example, the percentage of benzene is higher in gasoline "Circle K" and "Viada". There are more olefins and more Nestes fuels compared to German, British and Polish fuels.

Oxygenates, ethers, ethanol – These substances also increase the octane number, but they also have another disadvantage when gasoline contains a variety of oxygen-containing oxygen-containing compounds, which means that the heat of combustion of gasoline is reduced, and thus its efficiency.

"Ethanol has such an unpleasant trait that absorbs water vapor, which leads to the release of water that is dissolved in gasoline in gasoline, and water in contact with metal parts can cause corrosion," Korotkijs explained.

The results of ethanol are very similar, with oxygenates and ethers less pronounced for Nesta.

Oxygen content. The norm prescribes that it should not be greater than 2.7%, and this norm is observed in all samples, the figures are very similar – Nestei is better.

In general, all samples are in the normal range, without significant differences in samples, in individual positions, "Nestes" fuel from Finland is better.

Analysis of diesel fuel

Diesel fuel is not an octagonal figure, but one cetan number

"Prohibited method" of the price of diesel fuel samples

GBR (BP) 1.59 € / l

GER (Krimphoff) EUR 1.34 / liter

GER (Aral) 1.28 euro / l

POL (BP) 1.27 euro / l

POL (Lotos) 1.26 Euro / l

LAT (round K) 1.25 Euro / l

LAT (Viada) 1.24 € / liter

LAT (Neste) 1.23 euro / l

As a result, the fuel burns faster, faster, the engine increases the load, increases wear when it is used for a long time. If the Cetane number is higher, the engine is quieter, it decays, not rinsing, "explained the laboratory representative.

The higher the number, the lower the fuel consumption.

The best diesel for the UK, and two field models and Neste fuel, but the worst diesel fuel purchased from Latvia by Viada and Circle-K.

In addition, the number 50.7 and 50.2 is below the limit of the regulations of the Government of Latvia and the European Union standard, which is 51.

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

  • Lotus (Poland) 54.4
  • BP (United Kingdom) 54.1
  • BP (Poland) 53.9
  • Krimphoff (Germany) 53.5
  • Neste (Latvia) 53.2
  • Diesel (Russia) 51.6
  • Aral (Germany) 51.1
  • Viada (Latvia) 50.7
  • Krug K (Latvia) 50.2

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

But, for example, the Cetane number of British diesel is already approaching a 55-point mark, which, according to Nestes, was previously a diesel engine. 51 points exceed Russian fuel.

Looking for the results of an analysis of the Circle K itself, it turns out that the Cetane number is not measured at stations, but is based on fuel. The company sent an analysis from the Estonian laboratory "Analiit" to the program, which indicates that a specific diesel engine has a Cetane ratio of 51.7.

Fuel density. Density shows a specific mass of a liter of diesel that has a higher density due to higher calorific values, explains Correctri.

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

Aromatic hydrocarbons. It is not desirable for diesel fuel because the aroma is heavier and burning requires pressure. It is therefore not desirable for a diesel engine, but also from an environmental aspect – if the fuel does not burn, the aroma is toxic or even carcinogenic.

The best creators of Nestei, the British "British Petroleum" and the Polish "Lotus". The worst are Viada, Circle K and Diesel from Russia.

PNA – Polycyclic aromatic hydrocarbons. It has a particularly heavy flavor. According to the Latvian norm, the limit of eight points can not be exceeded.

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

FAME – the abbreviation of the methyl ester of fatty acids, known as biodiesel. Latvia usually uses either rapeseed methyl esters, maybe some other vegetable oil, but in Latvia it's usually rape oil. It is an additive for biofuel that is required to add diesel, at least for summer diesel. Usually in Latvia they are 4.5% – 5%.

Also seen "Viada" and "Circle K", it is obvious that, for example, in other European countries there is already a standard for biodiesel to be about 7%. But zero is Russia and Nestes diesel.

In Russia there are no such mandatory standards, but in the case of Nestes, this part is replaced by other renewable sources, abbreviated HVO – hydrolysed fatty oil, which can be done, but for which no analysis was performed, explained Neste. It is diesel, which is produced by recycling waste, oil, oil, which produces fuel that does not contain ponds.

Content of sulfur – The less, the better. Allowed norm 10. All samples within normal range. The best indicator for the Polish "Lotos" diesel and "Neste", the worst German "Krimhoff".

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

A good overall fuel figure from the UK, but our own "Circle K" and "Viadas" lose losses at this competition.

What can mean bad fuel?

Owners of the Varans car center, Andris Selevičs, told the program that the quality of fuel affects soot filters, oil filters, fuel filters.

However, drivers can see fuel quality after fuel consumption, "because a lot of cars in a diesel atmosphere are blurred with tea, which is only because the fuel does not burn" if the fuel is good, "the machine is moving forward and fuel consumption is low if fuel low quality – it's hard to start, high consumption. "

If the fuel does not burn, it develops calmly, they "facilitate all their work and therefore the car does not go well," Selevich explains. If the collector "goes", the air is inflated twice as low as necessary, and the car does not go out.

Diesel engines are much more efficient than fuels, but diesel is much more common in Latvia. Diesel fuel can lead to a drop in fuel injection due to poor fuel quality.

The tip of a truck is to test fuel quality by marking consumption by changing different companies.

Where does the fuel come from, which can be filled by Latvian gas stations?

The most popular Latvian fuel dispensers reported to take fuel:

  • Kruga K – Orlen plant in Lithuania, Mažeikiai.
  • Viada – Orlen plant in Lithuania, Mažeikiai.
  • Latvijas nafta – Orlen plant in Lithuania, Mažeikiai.
  • Factories "Virsi A" – "Orlen" in Lithuania, Mažeikiai.
  • "A Starte" – factory "Orlen" in Lithuania, Mažeikiai.
  • Factory "Kool" – "Orlen" in Lithuania, Mažeikiai.
  • Shell does not respond within three days.
  • Neste – fuel comes from Finland.

The oil refinery in Mažeikiai is a Soviet heritage that recycled crude oil from Russia through Belarus to the needs of the Baltic States. In 2006, it was bought by the Polish company PKN Orlen, which also owns the Butinga Oil Terminal in Lithuania, through which oil ships can be further exported, as well as the pipeline connecting Polock with the plant, and then with the Buting Terminal.

Alvis Erglis, Sales Director of Circle K Latvia, said that the fuel was purchased from the Orlen plant, buying every year and choosing the best supplier.

"In our case, we are able to determine our parameters for the manufacturer, we are asking us to produce concrete fuel. And here I really want to discuss the myth that all the fuels in the whole market come from one bore, one tank. Well, it's not completely safe" , said Eagle.

"Our demands are based on the standard set by the European Union, which is also separate for diesel and gasoline. [..] Additionally we add fuel-enhancing additives that further increase this quality and improve the performance and economy of the car, "says Eagle.

In the meantime, a member of the Management Board of Neste Latvia, Sales Manager Armands Beiziik, said that Neste is a refinery of oil with 70 years of experience and that all fuels coming to Latvia come from factories in Finland.

Fuel is shipped from Finnish ships, stored at the Terminal in Riga Freeport and then further distributed. Fuel is supplied without additives, additives that improve fuel quality, added to the terminal at the moment when the fuel carrier fills up and leaves the terminal.
