The United States continues to export MTBE, mainly to Mexico, Chile, and Venezuela
U.S. exports of methyl tert-butyl ether (MTBE), a motor gasoline additive, totaled 38,000 barrels per day (b/d) in 2017, primarily to Mexico, Chile, and Venezuela. MTBE was once commonly used in the United States but was phased out in the late 2000s as a result of water contamination concerns. Since then, fuel ethanol has replaced MTBE as a gasoline additive.
