Which gas stations in Latvia have better fuel from where it comes from and what indicators are generally good fuel? "Prohibited Techniques" explained this by transmitting fuel samples taken for analysis to several Latvian and British, German and Polish gas stations. The consignment also found that most of the fuel in the Latvian market came from the Mažeikiai factory and also advised on how drivers can control the fuel quality.
For the analysis to be the same, the program team used 5-liter cans, with the cheapest fuel available in a certain gas station – summer diesel and 95 pounds of gasoline.
Samples taken in Latvia:
- "Viada" the station in Riga, Maskavas street. The company now claims that it is a new one in Latvia, it has about 70 gas stations, most of which are taken from the company Lukoil, currently owned by the Austrian company Amic.
- "Neste" station in Riga, Krastā street. Next is a Finnish energy company, and there are also about 70 gas stations in Latvia.
- Circle K (formerly "Statoil") station. The network currently owns a Canadian company, with about 80 stations in Latvia, and is the largest fuel retailer.
- To make the picture even more complete, so-called smuggling or fuel from Russia, which is often imported into Latvia legally and enters the secondary market.
Samples taken abroad:
- In Britain, "British Petrolium" at Newmarket Station, near Cambridge.
- In Germany, "Krimphoff & Schulte" the Rhine station, near the border with the Netherlands.
- Germany, Berlin, Aral a British gas station and the largest network in Germany.
- In Poland, "British gasoline" station near the city of Chcel, between Poznan and the border with Germany.
- In Poland "Lotos" the station to the city of Kosice, between Poznan and Warsaw.
Samples with the Express Method were checked by the State Revenue Customs Revenue Service, they were quickest on basic fuel indicators, both determined by the European Union and Latvia's legislation. The test gives an understanding, it is a recognized and widely used method, because a profound analysis of analysis costs about ten times more expensive.

Petrol tested after research octane, followed by the name of the petrol type – whether it is 95 or 98. In all the samples tested everything is in order, with a test of Germany with the highest octane number and the 98's are likely to be filled.
"In popular science, the research october number is obtained in static conditions. Well, it may be an engine when it's free when nothing changes, simply drive the engine quietly and set the limit at which detonation begins," explained senior cheat expert Kaspars Korotkijs.
Indicator – gasoline density. The gasoline in Germany, Great Britain, Poland and Latvia – "Next" – is something better.
"If the density is higher, it is possible that gasoline has a higher combustion heat, so that it will have more energy in one liter of gasoline, but the engine is specially designed for gasoline so it is again within the limits of intelligence. If the density is too high , other parameters will suffer there and it will not be good for the engine, "explained Korotkijs.
Different types of hydrocarbons. All fuels are a single hydrocarbon compound, but each has different characteristics – one has more efficient energy sources, one smaller. Benzene, toluene, olefins – These types of hydrocarbons have a very high octane, which means they are very good, but they are considered to be hazardous to health and therefore their amount of fuel is limited.
Aromatic hydrocarbonAccording to Latvia's government, the 35-point limit must not exceed the limit of olefin. 18. The limit of benzene, which is the most harmful of these substances, is 1. All samples correspond to these limits. However, for example, the proportion of benzene is higher in the gasoline "Circle K" and "Viadä". There are more olefins and more is Nest's fuel compared to German, British and Polish fuels.
Syregener, ethers, ethanol "These substances also increase the octane, but they have another drawback when petrol contains many oxygen-containing compounds that are oxygenates, which means that the gasoline heat will decrease and, consequently, its efficiency.
"Ethanol has such an unpleasant trait that it absorbs water vapor, resulting in the release of water that is dissolved in petrol in gasoline. And water in contact with metal parts can cause corrosion," explains Korotkijs.
The ethanol score is very similar, with oxygenates and ethers less pronounced for Neste.
Oxygen content. The norm stipulates that it should not be higher than 2.7%, and this norm is observed in all samples, the numbers are very similar – a little better is Nestei.
In general, all samples in the normal range, with no significant differences in the samples, in individual positions, Finland's "Nestes" fuel is better.
Diesel fuel is not an octane, but one cetane number
"Prohibition of Method"
GBR (BP) 1,59 € / l
GER (Krimphoff) EUR 1,34 / l
GER (Aral) 1.28 euro / l
POL (BP) 1.27 Euro / l
POL (Lotos) 1.26 Euro / l
LAT (Circle K) 1.25 euro / l
LAT (Viada) 1.24 Euro / l
LAT (Next) 1.23 Euro / l
"The cetane number's essence is the ability to burn well. If the cetane number is low, the engine will cut. There is a momentous momentum between the moment and the combustion of the fuel. As a result, the fuel burns faster, faster, the engine increases the load, increases wear when used for long time. If the ceter number is higher, the engine is quieter, it crumbs, does not flush, "explained the laboratory representative.
The higher the cetane number, the lower the fuel consumption.
The best of diesel for the UK, both the two Polish models and Neste fuel, but the worst diesel fuel purchased from Latvia from Viada and Circle-K.
In addition, the figure is 50.7 and 50.2 below the limits of Latvian government regulations and the EU standard, which is 51.
Test results for all diesel samples and their cetals:
- Lotos (Poland) 54.4
- BP (United Kingdom) 54.1
- BP (Poland) 53.9
- Krimphoff (Germany) 53.5
- Next (Latvia) 53.2
- Diesel (Russia) 51.6
- Aral (Germany) 51.1
- Viada (Latvia) 50.7
- Circle K (Latvia) 50.2
The laboratory representative explains that these numbers are incorrect, and if the error is explained in favor of the company, 51 would be achieved.
However, for example, the cetan number on the British diesel is now approaching the 55-point mark, which, according to Nest, has previously been a pro diesel fuel. 51 points exceed Russia's fuel.
By asking for the results of the analysis of "Circle K" in itself, it turns out that the number of cetals is not measured at the stations, but it does in the fuel base. The company sent analyzes from the Estonian laboratory "Analiit" to the program, indicating that the specific diesel party has a cetane ratio of 51.7.
Fuel Density. Density indicates the specific mass of one liter of diesel that has higher density due to higher heat values, Correctry explained.
Here the numbers are equal, but best are "Circle K", "Viada", the best – in German fuel Krimhoff, but the differences are negligible.
Aromatic hydrocarbons. It is not desirable for diesel fuel because the aroma burns harder and burning requires pressure. Therefore, it is not desirable for a diesel engine, and even from an ecological point of view – if the fuel is incomplete, the aroma is toxic or even carcinogenic.
The best creators of Nestei, British "British Petrolium" and the Polish "Lotos" diesel. The worst are Viada, Circle K and Diesel from Russia.
PNA – polycyclic aromatic hydrocarbons. It has a particularly large aroma. According to the Latvian norm, the limit of eight points can not be exceeded.
Test limits are respected everywhere, but the worst indicators are the German "Arala" and "Viadas" diesel, the best indicators – "Next", British and Polish "British gasoline".
FAME – a shortening of fatty acid methyl ester, commonly known as biodiesel. Latvia usually uses either rapeseed oil methylesters, maybe any other vegetable oil, but in Latvia it is usually rapeseed oil. It is a biofuel additive that is mandatory to be added to diesel, at least for summer diesel. Usually in Latvia they are 4.5% – 5%.
"Viada" and "Circle K" can also be seen, it is obvious that, for example, in other European countries there is already a standard that the biodiesel land should be around 7%. But nothing is Russia and Nine's diesel.
There are no such mandatory standards in Russia, but in Nest's replacement this part of other renewable resources, the shortened HVO hydrolysed fatty oil, which can be done but for which no analyzes have been made, explained Neste itself. It is diesel, produced by recycling waste, processing oils, oils, which provides a fuel that does not contain puddles.
sulfur content – the less the better. Permissible norm 10. All tests in the normal area. The best indicator for Polish "Lotos" diesel and "Next", the worst German "Krimhoff".
The overall conclusion is that the best diesel fuel from the Polish gas station Lotos is a high cetane, low aroma, low sulfur content, similar to the Latvian "Nesti".
Good overall figures for British fuel, but our own "Circle K" and "Viadas" numbers lose in this competition.
Owners of "Varāns" Center Andris Selevičs told the program that the fuel quality affects soot filters, oil filters, fuel filters.
But drivers can assess fuel quality after fuel consumption, "because many diesel cars have chewed and this is just because the fuel does not burn" if the fuel is good ", the machine is moving forward and the fuel consumption is low if the fuel is low quality – difficult to start, high consumption ".
If the fuel does not burn, it develops smoothly, they "lighten up their entire production, and therefore the car does not go as it should", explains Selevič. If the collector "get off" the air is inflated twice less than necessary and the car does not go away.
Diesel engines are much more fuel efficient than gasoline, but diesel is much more common in Latvia. Diesel fuel can cause fuel injectors to fall due to poor fuel quality.
The truck's advice is to test the fuel quality by marking consumption by changing different companies.
Most popular Latvian fuel traders reported that fuel was taken:
- Circle K – Orlen plant in Lithuania, Mažeikiai.
- Viada – Orlen plant in Lithuania, Mažeikiai.
- Latvijas naphtha – Orlen plant in Lithuania, Mažeikiai.
- "Virši A" – "Orlen" factories in Lithuania, Mažeikiai.
- "A Start" – "Orlen" factories in Lithuania, Mažeikiai.
- "Cabbage" – "Orlen" factories in Lithuania, Mažeikiai.
- Shell does not respond within three days.
- Next – the 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 acquired by the Polish company PKN Orlen, which also owns the Butinge Oil Tranship Terminal in Lithuania, through which oil products can be further exported by vessels and also a pipeline connecting Polock with the factory and then with the Butinge Terminal.
Alvis Ērglis, Director of Sales of Circle K Latvia, said that fuel was purchased from Orlen factory by purchasing each year and selecting the best supplier.
"In our case we can determine our parameters for the manufacturer and ask us to produce concrete 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." Well, that's not for sure, said Eagle.
"Our requirements are based on a standard set by the European Union, which is separate for both diesel and gasoline. [..] We also add additive for fuel enhancement that further increases this quality and improves performance and economy for cars, "said Eagle.
At the same time, Next Latvia's Board member, Retail Manager Armands Beiziik, said Neste is a fuel oil refinery with 70 years of experience and that all fuel coming to Latvia comes from the company's factories in Finland.
The fuel is shipped from Finland by ship, stored at the Freeport terminal in Riga and then distributed. The fuel is delivered without additives, additives that improve fuel quality, added to the terminal when the fuel container is loaded and it is running out of the terminal.
