The move comes in response to the government move to introduce price regulation on the market.
A number of gas station chains in Ukraine have suspended the sales of "premium" brands of petrol and diesel fuel.
The operators say the move is a response to the Cabinet's decision to introduce state regulation of fuel prices, setting the camp on trade markup.
The OKKO network reported that the Cabinet's move made the sale of "premium" fuels unprofitable.
"From May 15, in connection with the introduction of state regulation of fuel prices, OKKO gas stations are suspending the sale of PULLS 95 and PULLS Diesel. This is due to the fact that the sale of fuel of these grades at the price set by the Cabinet of Ministers for May is unprofitable for the network," the statement says.
The WOG network has made a similar move, also linking it with the introduction of state regulation of fuel prices.
"We are forced to cease the sales of premium 95 Mustang fuel and DP + Mustang," the statement said.
The restrictions are not set to apply to A-95 gasoline and Euro-5 diesel fuel.
The Focus outlet says a similar situation with premium fuels is being observed at the KLO network. "According to the gas stations' staff, the sale of the said types of fuel has been suspended at all of the network's gas stations," the report reads.
