Gasoline prices were flat in March after dipping 0.3 percent in December through February.
Energy Minister Sergei Shmatko said in mid-January that an agreement had been reached with oil companies to "freeze" their fuel prices at the end-2011 level. Apparently, that agreement expired last month. Compared with April of last year, gasoline prices were up 12.1 percent.
