If America is becoming energy independent, why are gasoline prices going up? In this video, Tyler Crowe describes how U.S. oil refiners are buying cheap U.S. oil, refining it, and then exporting it for a premium. Refiners like Valero (VLO 2.84%), Phillips 66 (PSX 1.41%) and Marathon (MPC 2.30%) are making a killing on exporting gasoline and diesel to Latin America and Europe. While that's not good for the consumer, investors should do well. Tyler likes Valero best due to its high dividend.
