The most adequate network of gas stations in Kazakhstan, the highest quality gasoline at low prices! I recommend refueling only at these gas stations, I personally traveled around Kazakhstan several times and filled all the fuel from them, I also tried SINOIL and energy gasoline... But Kazakh drank the best!
It's a very good gas station. And the fuel quality is excellent. Water is all you need, there is a toilet, a shower, even there is. I liked it, I recommend it.
