The low price of fuel is due to the low quality of fuel. The fuel quality does not match the declared one. You fill up cheaper and more, and you drive as much or even less.
Of the advantages, I can note that the network is large and you can easily find the nearest or more convenient route.
The service is also good.
The speakers are comfortable, entry and exit is not difficult.
In the evening, you can get on a convoy of buses, which apparently have a contract.
You can refuel, but not on a permanent basis.
Sometimes I refuel at this gas station, but only because it is very close to home, but in general I do not advise. Low price,low fuel quality,gasoline burns fast,diesel fuel of poor quality
